Into Unscientific Chapter 207

  Chapter 207 Only the boss is left

  After being inspired by Lao Su.

  Xu Yun didn't dare to neglect.

   Immediately chose to return to the scene, and informed Yu Yuanyong and others of this idea.

   "What? Using a liquid as an intermediate?"

  After hearing this idea.

  Yu Yuanyong glanced at the old Su who had a face full of "I am a passerby" in surprise, and fell into deep thought:

   "The iron ion beam density we use is a low-energy ion beam of 110keV, and three bands should be misplaced in one cycle."

   "If we set up a constant-period liquid device, when the wrong peak occurs, the band will be fed back to balance"

   "Hiss, it seems really possible?"

  Considering that some students may not understand the nature of intermediates in this reaction, here is a very simple example to illustrate—it is really a very simple one.

  Suppose there is a very long conveyor belt, the height of the connected inlet is 4 cm, and 95% of the items on the conveyor belt are 3 cm.

   Three centimeters versus four centimeters.

   Those items can naturally pass through the feed port smoothly.

  But in addition to these three-centimeter items, a 5-centimeter giant will appear on the conveyor belt every certain period—say, 30 seconds.

   Due to various restrictions, the height of the feed port cannot be raised permanently. As a result, material jams will occur.

   At this moment, someone proposed a solution:

  Although we cannot permanently increase the feed inlet, we can set a program.

  So that whenever a five-centimeter giant cycle appears, the feed inlet can be briefly raised to six centimeters for a few seconds, wouldn't it be good?

  Maybe this approach requires a certain cost, but it is obviously much lower than permanently increasing the feed inlet.

   At least within the acceptable range.

  Although in the practical operation today, the issues that Xu Yun and others need to consider are much more complicated than the above examples.

  But the two are actually interlinked in nature, and they both balance certain abnormal energies through the docking cycle.

  Think here.

  Yu Yuanyong couldn't sit still for a while, he turned around and said to Xu Yun:

   "Dr. Xu, what do you think should be used as a balance liquid?"

  Xu Yun made a figure horoscope with his right hand, covering it in front of his nose, and picked up the report from the table again with his left hand, and looked at it carefully.

  Chemical intermediates.

  The word is as it should be, referring to some common intermediate substances in the chemical industry, which can be subdivided into 11 categories.

  These 11 categories are in addition to additives, chemicals and daily chemicals.

   Also includes liquids such as reagents, paints and dyes.

  But what Xu Yun and Yu Yuanyong are discussing is obviously not this kind of conventional liquid, but other special liquid materials with certain concentrations.

  This kind of material must first have the property of not participating in subsequent reactions, and at the same time have suitable properties, and it must not react with iron ion beams.

   In this way.

  A considerable part of the salts are excluded.

  The second thing to consider is the intermolecular force of this material, that is, the coordination of the molecular space configuration in the hybrid orbital.

   So Xu Yun thought about it.

  Take the pen and paper. Write down a noun and hand it to Yu Yuanyong:

   "Director Yu, what do you think of this?"

  Yu Yuanyong took a look at the results:

   "Potassium ferricyanide?"

  Xu Yun nodded and explained:

   "The ligand of potassium ferricyanide is CN-, and the coordination number is 6."

   "If I remember correctly, its charge-to-mass ratio at the 110keV energy level should be around 11.5. It seems to be 11.54, which is very close to our requirements."

   "At the same time, because its central atom is a ferric ion, it can only react with ferrous ions, and there is a congenital combination barrier with the iron ion beam."

   "In addition, although potassium ferricyanide is poisonous, it has a wide range of applications in the industrial field. It should meet the requirements as an intermediate in closed equipment."

  As Xu Yun said.

  Potassium ferricyanide is a red crystal, its aqueous solution has yellow-green fluorescence, and when it meets ferrous salt, it will form a dark blue precipitate.

  At the same time, it is easy to reduce in sunlight, and can be completely decomposed by burning to produce highly toxic potassium cyanide and cyanide.

  Students who were poisoned to death by potassium cyanide in their previous life should know this.

  Potassium cyanide is an alkaline substance that directly stimulates the mucous membranes to produce irritation, leading to faster and deeper breathing, fatigue, and headache.

   Then you start to have difficulty breathing and your blood pressure rises.

  At the same time, because the tissue cannot utilize oxygen, the oxygen saturation of the venous blood increases, which makes the skin and mucous membrane appear cherry red

  Eventually you will have twitches and muscles all over your body will start to relax.

  He died quickly due to symptoms such as cardiac arrest and multiple organ failure.

   Therefore, in the civilian field, potassium ferricyanide has always been a kind of substance that is strictly controlled.

   But in the industrial field, this thing is still very common.

  It is widely used in photographic paper, printing, pharmaceutical, fertilizer, steel and other industries.

   It is a kind of substance with high popularity and is not illegal.

  Think here.

  The brilliance in Yu Yuanyong's eyes became brighter, and he pondered:

   "Potassium ferricyanide. Potassium ferricyanide seems to have a chance?"

   Then he thought for a while, looked at the assistant beside him, and asked:

   "Xiaoqian, you can search the database to see where the stretching vibration of the CN bond occurs under the condition of potassium ferricyanide at ten atmospheres."

   The little money Yu Yuanyong is talking about is a rare girl in the chemical industry. She has short hair and looks quite capable.

  I saw her click on the keyboard a few times, then quickly raised her head and replied:

   "Found it, the interval is 2356-3091cm^-1."

   "What about free radicals?"

  Xiaoqian tapped the keyboard a few more times:

   "45 etc."

   "45 wait"

  Yu Yuanyong repeated the number thoughtfully, and then glanced at the previous test results.

  Although detailed peak control still needs experimental calculation, it can only be judged from the perspective of these data.

   Potassium ferricyanide seems like a good choice?

  In fact, the intermediate that Yu Yuanyong first thought of was cobalt-iron carbonate compound salt, which is a substance commonly used in lithium batteries.

   But cobalt-iron carbonate complex salt, as its name suggests, is a complex with very complex components.

  Although it can also achieve a good intermediate effect in the molten state, the preparation difficulty and cost of molten cobalt-iron carbonate composite salt are undoubtedly much higher than that of potassium ferricyanide aqueous solution.

   If it is said that this is a laboratory preparation, it is better to say something.

   After all, the amount needed in the laboratory is not much, and the mode is different.

   Most of the production in the laboratory does not need to consider the cost too much. If the product can be obtained, the method can be regarded as effective, and it can even write a paper or something.

   But the industrial sector is different.

  In the industrial field, various practical issues must be considered. To put it bluntly, it is the profit rate. Naturally, the simpler and cheaper it is, the better.

  This is also the reason why substances such as hydrochloric acid are divided into two methods: laboratory production and industrial production—predictably, some people will say that the sentences are mixed.

  Think here.

  Yu Yuanyongdang even made a decision:

   "Attention all departments, let's try potassium ferricyanide first, and then consider other substances if it fails, start preparing immediately!"

  As a well-known heavy industry group in China, Hanhua Factory naturally has a lot of potassium ferricyanide in reserve.

   So fast.

  A newly prepared high-concentration potassium ferricyanide was put on the test bench as a substitute for catechol.

  At the same time, consider that the key this time is the softening of the feedback band, and the key is the locking of the peak.

   Therefore, Yu Yuanyong deliberately adopted the detection method combining Fourier transform infrared spectroscopy and Raman spectroscopy, which is very specific.

   Half an hour later.

  Yu Yuanyong calculated the cycle of the rotating equipment, and the second round of experiments officially started.

   "Drip—咻咻咻—"

   Another fifteen minutes passed.

  The results of the report are officially released.

  Yu Yuanyong took the report and glanced at it hastily, and then he looked happy, and said to Xu Yun:

   "Dr. Xu, the absorption peak shifted to the right by 40nm after iron ion implantation, but the selective peaks at positions 530 and 1060 did not appear!"

   "There is no doubt that your thinking is correct, the special liquid completely balances the interference of the feedback band!"

   Hear this statement.

  Xu Yun and Lin Zhenhua immediately beamed with joy.

  As Yu Yuanyong said.

  This report basically affirms Xu Yun's or Lao Su's thinking, which means that transition metal catalysis is no longer an insurmountable moat.

  As early as when they came to the laboratory, Yu Yuanyong introduced that their team had broken through some pre-technical obstacles, and was stuck at the molecular sieve step.

   After passing the molecular sieve, the only problem left is the equipment for directional cyclization.

   Indeed.

  Oriented circularization is the last barrier, and the difficulty may be higher than the sum of all the previous links.

   But at least as far as the overall situation is concerned.

   Just one big problem left to solve is definitely many times better than having a bunch of problems left.

   It's like online games.

  Before officially attacking the boss, most players will clean up the small monsters and elite monsters first, and then focus on the single target of the boss.

Of course.

  Before launching the final attack, Yu Yuanyong and the others still have one problem to solve:

   That's how to adapt the transition metal to be the lowest cost metal, lanthanum.

  However, this problem belongs to the category of pure industrial optimization, which is not within the competence of Xu Yun and others.

  In addition, the specific optimization will not produce results in a short while, at least two days or more.

  So after a simple handover.

  Xu Yun and his team temporarily left the laboratory and were brought by Zhao Haiyang to the guest house of Hanhua Group.

  Hanhua Group's guest house is a newly renovated eight-story building. The interior decoration is not luxurious, but it looks quite grand.

  The specification of the single room in the guest house is a 1.8-meter bed, there is no bathtub in the bathroom, and there is only a desk in the room except for some basic facilities.

  The curtains in the room are electric, and there is also a Xiaodu on the bedside table to provide voice assistance.

  At the same time, as Lin Zhenhua said before, the sound insulation effect of the room is extremely good:

  Xu Yun played a recording of snoring in the ear that a friend gave him to ward off evil spirits in the next room, and found that the sound could not be heard at all.

all in all.

   It is a standard four-star specification.

  However, Xu Yun did not choose to take a shower and then go to bed to rest for a while. Instead, after putting away his luggage, he met Lao Su outside the door.

   Then he explained some things to Tang Li, then took the vehicle prepared by Zhao Haiyang and drove to Yongcheng Railway Station.

  The destination of the two of them is very clear:

   Arrive at Zhenjiang first.

   Then go to Wuzhou Mountain.

  Last arrival.

  Su Song's tomb.

   Grandma was admitted to the ICU yesterday. She was out of danger in the morning, but she still needs to be observed for a day or two.

   It was another all-night stay. Because of the crisis, I didn't have the time to code all night. In the morning, my grandmother was out of danger and only coded for four hours. I couldn't hold it anymore, so today is a bit short

   Some students in the group suggested that I take a leave of absence. In fact, I have already explained that taking a leave of absence once means that the chasing value will plummet. This situation cannot be avoided by anyone.

   Like our book is estimated to be close to 3,000, and this chapter says about 150, the readers of those comments are actually only a small part.

   The idea of ​​quite a few readers is actually very simple. I provide works and they subscribe, and neither party owes them anything.

   So I really dare not say goodbye, especially since I can't go out these days, the manuscript fee has become my most stable source.

   It is estimated that grandma will live in ICU for two or three days, more than 7,000 a day, and the ICU medical insurance can only reimburse 40%.

   So I appreciate the kindness of persuading me to ask for leave. I am very grateful if you can subscribe and support~
