Into Unscientific Chapter 622

 In the basement.

At the same time Xu Yun was in a trance.

Lao Guo on the side looked at Wang Yuan and Gao Yuanming with some curiosity, paused for a few seconds, and asked:

“What do you think of Comrade Lao Wang, Lao Gao, and Yongzhong's idea?”

Wang Yuan and Gao Yuanming looked at each other after hearing this. Wang Yuan thought about it for a moment and said:

“Gong Guo, from a technical point of view, I personally think that nitrogen cluster compounds are still quite difficult.”

“After all, our understanding of small molecule substances is still too shallow today. The chemical structure of a substance is one thing, but its synthesis is another.”

“For example, we have known the concept of carbon-carbon bonds for a long time, but at most we can guide the formation of carbon-carbon bonds through chemical reactions, and we are completely unable to combine point-to-point carbon-carbon bonds at the molecular level.”

Hearing what Wang Yuan said.

Xu Yun, who had recovered his senses, also nodded subconsciously.

Schoolmates who have lived two hundred years old should all know this.

 The modern scientific community's understanding of chemical structures can be traced back to 1831, the year Aveline was born. (Who is this person? He sounds familiar. Ahem.)

At that time, Libisi discovered silver fulminate AgONC, and analysis proved that both compounds contained one Ag, N, C, and O atom.

The authoritative Archbishop Bericeus defined this phenomenon as "isomerism", in which the component is the molecular formula and the structure is the structure. The molecular formula is the same but the structure is different.

Later, Kekulé followed the example and proposed the methane type. This type showed that carbon-carbon can also form self-bonding, and then derived the structural formula of ethane.

 Then in 1861, Butrelov on the other side of the Bear formally proposed the concept of chemical structure.

He believes that molecules are not a simple accumulation of atoms, but are arranged in a certain order through complex chemical binding forces. The way in which atoms are related to each other is the chemical structure of the compound.

 Under the guidance of this theory.

He synthesized tert-butyl alcohol, isobutylene, dimethylcarbinol and certain sugar compounds, discovered the polymerization reaction of isobutylene, studied the isomers of butadiene, discovered the phenomenon of cross-isomerism, and also proposed the theory of isotopes. Assumption.

At this time, there have been very solid research results in the theoretical aspects of chemical structure.

But on the other hand.

Since the accuracy of instruments is simply limited by the industrial level, the chemical industry is still superficial in terms of technical applications, and it is impossible to exploit the treasure mountain.

This is like a veteran driver who has read countless movies, but in reality he is a hard-working guy who doesn't even have a girlfriend.

No matter how many postures you have seen in movies, you cannot successfully apply them in reality even if you have only a theory at your fingertips.

However, facing Wang Yuan's words, Yu Yongzhong shook his head again and gave another point of view:

“Wang Gong, I have some other opinions about your words.”

“First of all, as you said, the production of total nitrogen compounds is indeed very difficult. I also admit that it is difficult for us to achieve its production in terms of technology—let alone mass production, even if it is implemented in the laboratory, there is little hope.”

 “But what if we take a step back?”

Wang Yuan was suddenly startled and asked inexplicably:

 “Take a step back? What does this mean?”

 “Look.”

Hearing this, Yu Yongzhong pursed his dry mouth in excitement, pointed at the structural formula he had written, and explained:

“Judging from the type of structural formula, there should be several combinations of possible nitrogen cluster compounds.”

“Among them, total nitrogen compounds are obviously the most powerful. As the name suggests, this thing only contains N5 groups. I guess there should be two types of Yin and Yang - but this issue is not important at the moment and can be put aside for the time being.”

“The key point I want to say is that in addition to all-nitrogen compounds, there are also two categories: diazo compounds and azide compounds.”

“For example, for azide compounds, if I remember correctly, the arylpentazole was developed across the sea in 1956, and we also mastered the related technology not long ago.”

“That is, as long as we can get the sodium azide solution, theoretically this compound should be synthesized with probability”

 Hear this.

 A flash of lightning suddenly flashed in Xu Yun's mind.

yes

 Why didn't you think of it yourself?

 Between CL20 and N5 total nitrogen anion salt, there are two substances that are unstable but can become stable, namely

  Diazo compound N2, and azide compound N3.

Just like the precursor of N5 is arylpentazole, azide compounds also have a precursor, which is aryltetrazole.

The raw material for the synthesis of aryltetrazole is sodium azide, which can be prepared by reacting sodium nitrite with hydrazine hydrate:

Dissolve hydrazine hydrate in anhydrous ether, add a mixed solution of sodium hydroxide and ethyl nitrite under water cooling, and react under ice cooling.

 After the reaction is completed, heat slowly to return to room temperature.

 Then crystallize out, filter with suction, take out the crystals, wash with methanol and diethyl ether, and then recrystallize in water to prepare sodium azide:

C2H5ONO+NH2·NH2·H2O+NaOH→NaN3+C2H5OH+3H2O.

Hydrazine was first isolated by Curtius in 1887. In 1907, Rashi invented a method to prepare hydrazine hydrate by reacting ammonia and sodium hypochlorite.

 Neon started producing hydrazine hydrate at Otsuka Pharmaceutical Factory in 1939. In the 1950s, Yanjing, Shanghai and other places in my country also started producing hydrazine hydrate, so hydrazine hydrate is not a rare thing.

 Wait until the sodium azide solution is generated.

As long as the quaternary ammonium resin is washed with DMF, ethanol and deionized water, added to it, and then rinsed several times with methanol and ether, the polyazide compound can be extracted by vacuum filtration.

This step is relatively safe, it will not explode in the drop weight test, and the properties of the wet product are relatively stable.

Of course.

  There is nothing further to say.

all in all.

From a technical point of view, Yu Yongzhong's idea does seem to be feasible?

 Mom.

If the rabbits can really come up with N3, it will be great fun.

 This is the mid-twentieth century after all

 It is true.

Yu Yongzhong's idea is only feasible. Xu Yun is not sure whether it can be implemented and how long it will take to implement it.

  But if everything is fine.

Even if it is only successfully produced in the laboratory, N3 can still be used in rabbits' nuclear weapons test explosions.

After all, the detonating explosive of a complete atomic bomb is about 2,000 kilograms. When converted to N5, which is the total nitrogen anion salt, it is about 200 kilograms, CL20 is about 600 kilograms, and N3 is estimated to be about 400 kilograms.

Even including the consumption of cold explosion experiments, explosives of this magnitude will not exceed 1.5 tons.

The research and development cost of 1.5 tons of N3 is an unaffordable figure for any individual in this era, but in the face of the huge machine of the country, it is not a particularly high expenditure.

Of course.

If the Rabbits are really determined to develop N3, Xu Yun will definitely have to think of some ways to add some technologies, which is actually a difficulty.

 First of all, he had to ensure that he could not go too far when using his skills, otherwise it would be easy to reveal his perfectly concealed identity as Han Li.

Secondly, Xu Yun doubted whether the organization would take their ideas seriously given the current status of Yu Yongzhong, Wang Yuan and others.

This is not to say that the organization is short-term, but at present, CL20 is enough for rabbits to use for several years.

Just like when you buy a computer in later generations, 5,000 yuan is enough for daily use. There is no need for 8,000 or even tens of thousands of dollars. Many people will not be too willing to spend that money.

But if you know that Black Myth Wukong is about to be released to public beta, you might be able to grit your teeth and get a good configuration.

Well, it's just a metaphor, please don't substitute it into reality.

all in all.

 Because of this reason, even if Lao Guo is present alone, the 'weight' is not enough.

Hence, Xu Yun must find a way to bring down at least two more big guys like Lao Guo - such as Qian Wushi or Li Jue.

After all, you can't suddenly have a big boss from the capital appear in front of Xu Yun and listen to him tell the story again, right?

 impossible, absolutely impossible!

If this kind of thing can happen, Xu Yun took the one given to him by Mr. Guo Feng Kamen and said to be used by Maxwell. Half of it was chewed by Sun Junren and Ye Duzheng snatched it away. Ye Duzheng didn't take two bites and was eaten by Qian Wushi He snatched it away, and now Liu Bosheng gnawed it and sent it back to the base. The ax that was currently in Lu Guangda's mouth gnawed it out on the spot!

Hmm, the kind of thing you would do with an adult black soldier fly sandwiched between you and eat it in front of the boss!

Xu Yun then talked with Yu Yongzhong and others about some CL20-related content, and then left the basement with Lao Guo.

 It was exactly what Xu Yun thought.

Lao Guo only said that he would relay the relevant information to Li Jue, and did not take Xu Yun to the factory office to report in person - in Lao Guo's view, CL20 is the focus of the base's research and development, and N3 can be decided by the capital. .

I don't know if it's a coincidence or not.

 After finishing the conversation with Yu Yongzhong and others, the base experienced a relatively rare period of calm.

During this period, various projects at the base have been moving forward smoothly. Although there are not many stage-level results, they have not encountered any obvious problems.

Xu Yun also had a rare few days of leisure, and even had time to go fishing in Qinghai Lake - the catch was a rain shoe, a bamboo hat, a snake and a discarded grenade.

 But just like all novels except "The Son-in-law" will have a finale, no matter how peaceful the day is, there will be a day when it is broken.

 Three weeks later.

 September 25th of that year was the 76th day of Xu Yun's journey.

 At this moment.

Xu Yun, Lao Guo, Wang Ganchang, Cheng Kaijia, Da Da, Zhao Zhongyao and others all gathered at the seventh branch of the base.

 As one of the leading branches in the base, Branch 7 is mainly responsible for radiochemistry and neutron physics experimental functions.

For example, Liu Youcheng's chemistry laboratory and the radioactive nuclear component R&D coordination and research team led by Wang Ganchang are all here.

In addition, the drug research and development teams led by Lou Zhicen and Tu Luming are also located in the factory area, each occupying a small building.

However, today Xu Yun and others came to the Seventh Factory Area not to find the above project teams to inspect the project, but because they received a notice from Li Jue's assistant Zhou Cai not long ago.

The tandem proton accelerator that Xu Yun has been waiting for has arrived at the base early this morning!

 This is also the aspect that Xu Yun is most concerned about in the entire multi-party transaction.

at the same time.

This accelerator is also the largest transaction Xu Yun has made since he traveled through time.

  It can be said that throughout modern history, there have not been many transactions of this magnitude.

Not to mention that this accelerator can bring extremely huge benefits to the rabbits. In Xu Yun's view, its importance is on the same order as the atomic bomb.

  After all, atomic bombs are deterrent weapons in many cases, and nuclear war may indeed break out in the future, but at least until 2023, the confrontation in the theoretical field will be more intense.

For example, the news about room-temperature superconductivity has caused countless rumors.

Now, Xu Yun will uproot those obscene temples of cows, ghosts and snake gods in advance in this era.

 Subsequently, under the leadership of Zhou Cai, Xu Yun, Lao Guo and his party quickly arrived outside a building.

This building covers an area of ​​about thousands of square meters, which is obviously larger than other buildings, but it is only one floor high.

Seeing Zhou Cai step forward and open the door, Lao Guo took the opportunity to turn his head and introduced Xu Yun in a low voice:

“Xiao Han, this was originally a warehouse where materials were stored in the Seventh Branch Factory. For example, the special cement used before was stored here.”

“The tandem accelerator arrived suddenly. The base vacated the warehouse before they had time to excavate the underground laboratory.”

Xu Yun nodded clearly.

I see

 He was wondering when such a building appeared on the base, and what happened to the co-authorship.

The special cement Lao Guo mentioned is not the high-strength quick-setting cement that everyone knows in later generations, but the special materials used in the previous construction of detonation test sites.

That special cement was mixed in Liu Youcheng's laboratory and divided into wet materials that needed to be applied quickly and dry materials that could be stored for a certain period of time.

Not to mention wet materials, they will be scrapped if not used for a period of time. Dry materials are placed in this warehouse and will not be taken out for use until it does not rain.

More than a month has passed since Xu Yun proposed the transaction plan. This time is obviously not enough for the base to build another underground laboratory.

 In addition, the U2 reconnaissance aircraft can no longer fly to the mainland, so the base temporarily placed the tandem accelerator in this warehouse.

A few minutes later.

Zhou Cai, who had confirmed the situation internally, returned to the crowd and said:

“Dear leaders, the tandem accelerator has been assembled according to the drawings given by the British. You only need to put on shoe covers to enter the compartment to visit.”

 Hear this.

Including Zhao Zhongyao, Cheng Kaijia and others, the faces of all the base leaders could not help but show eagerness to try.

 This is an 80MeV accelerator.

 Subsequently, with the cooperation of several experimental department staff.

More than a dozen leaders put on shoe covers one after another and walked into this low building.

Note:

LK99 The Chinese Academy of Sciences has published a paper, arXiv.2308.04353. I have to do the re-examination all night tonight. I suddenly found that I, the bystander, seemed to have become a coolie.
