He immediately chose to return to the scene and informed Yu Yuanyong and others of this idea.
"What? Use liquid as an intermediate?"
After hearing this idea.
Yu Yuanyong looked at Lao Su with a surprised look on his face, saying "I'm just a passerby", and immediately fell into deep thought:
"The iron ion beam density we use is a low-energy ion beam of 110keV, which should produce three spectral band peaks within one cycle."
"If we set up a constant-period liquid device, we can feed back the band to balance it out when peak shifts occur."
"Hey, it seems really possible?"
Considering that some students may not understand the properties of the intermediates in this reaction, here is a very simple example to illustrate. It is really very simple.
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 opening smoothly.
But in addition to these three-centimeter items, a giant five-centimeter object will appear on the conveyor belt every certain period, such as 30 seconds.
However, due to various restrictions, the height of the feed port cannot be permanently raised. As a result, materials will get stuck.
At this moment, someone proposed a plan:
Although we cannot permanently increase the feed opening, we can set a program.
Wouldn't it be great if the feed opening could be briefly raised to six centimeters for a few seconds every time a five-centimeter giant appears?
Perhaps this approach requires a certain cost, but it is obviously much lower than permanently increasing the feed opening.
At least it's within an acceptable range.
Although in today's practical operation, the issues Xu Yun and others need to consider are much more complex than the above examples.
But the two are actually interoperable in nature, and both use docking cycles to balance certain abnormal energies.
Think of this.
Yu Yuanyong suddenly couldn't sit still. He turned around and said to Xu Yun:
"Dr. Xu, what do you think should be used to make the balancing liquid?"
Xu Yun made a figure of eight with his right hand and covered it in front of his nose. He picked up the report from the table again with his left hand and looked at it carefully.
Chemical intermediates.
As the word suggests, it refers to some common relay substances in the chemical industry, which are subdivided into 11 categories.
These 11 categories include additives, chemicals and daily chemicals.
Also includes liquids such as reagents, paints and dyes.
However, what Xu Yun and Yu Yuanyong were discussing was obviously not this type of conventional liquid, but other special liquid materials of some concentration.
This material must first have the property not to participate in subsequent reactions, have suitable properties, and must not react with the iron ion beam.
This way.
A considerable part of the salts have been eliminated.
The second thing to consider is the intermolecular force of this material, that is, the coordination of the molecular spatial configuration in the hybrid orbital.
So Xu Yun thought for a while.
He took the pen and paper, wrote down a noun, and handed it to Yu Yuanyong:
"Director Yu, what do you think of this?"
Yu Yuanyong’s 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 about 11.54 specifically. It is very close to our requirements."
"At the same time, because its central atom is a ferric ion, it will only react with ferrous particles, and there is an inherent chemical barrier to the iron ion beam."
"In addition, although potassium ferricyanide is toxic, its application range in the industrial field is actually very wide. It should be suitable to be used as an intermediate in closed equipment."
As Xu Yun said.
Potassium ferricyanide is a red crystal, the aqueous solution has yellow-green fluorescence, and when it encounters ferrous salts, it forms a dark blue precipitate.
At the same time, it is easy to reduce in the sun, and can be completely burned after burning, producing highly toxic potassium cyanide and cyanide.
Students who were poisoned by potassium cyanide in their previous lives should all know this.
Potassium cyanide is an alkaline substance that directly stimulates mucous membranes and can cause irritation, leading to faster and deeper breathing, fatigue, and headaches.
Then you will start to have difficulty breathing and your blood pressure will increase.
At the same time, because the tissues cannot utilize oxygen, the venous blood oxygen saturation increases, causing the skin and mucous membranes to turn cherry red.
Eventually you will have twitches and your muscles will begin to relax.
As a result, heartbeat stops, multiple organ failure and other symptoms lead to rapid death.
Therefore, potassium ferricyanide has always been a strictly controlled substance in the civilian field.
However, 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 very popular and not illegal substance.
Think of this.
The light in Yu Yuanyong's eyes became brighter and he pondered:
"Potassium ferricyanide seems to have a real chance?"
Then he thought for a moment, looked at the assistant beside him, and asked:
"Xiaoqian, please search the database and see where the stretching vibration of the CN bond appears under the condition of ten atmospheres of potassium ferricyanide."
The Xiao Qian mentioned by Yu Yuanyong is a girl who is extremely rare in the chemical industry. She has short hair and looks quite capable.
She clicked on the keyboard a few times, then quickly raised her head and replied:
"I found it, the range is 2356-3091m^-1."
"What about free radicals?"
Xiaoqian tapped the keyboard a few more times:
"Wait 45."
"Wait for 45"
Yu Yuanyong repeated the number thoughtfully, and then looked at the previous test results.
Although detailed peak control still requires experimental calculations, it can be judged from the perspective of these data alone
Potassium ferricyanide seems to be a good choice?
In fact, the intermediate that Yu Yuanyong originally thought of was cobalt iron carbonate complex salt, which is a substance commonly used in lithium batteries.
But cobalt iron carbonate complex salt is just as its name suggests. It is a complex with very complex ingredients.
Although it can also achieve good intermediate effects in the molten state, the preparation of molten cobalt iron carbonate composite salt is undoubtedly much more difficult and costly than potassium ferricyanide aqueous solution.
It would be easier to say that this is a laboratory preparation.
After all, the amount required in the laboratory is not large, and the modes are also 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 considered effective, and it can even lead to a paper or something.
But it's different in the industrial field.
In the industrial field, various practical issues must be taken into consideration. To put it bluntly, it is the profit rate. Naturally, the simpler and cheaper the better.
This is also the reason why substances such as hydrochloric acid are divided into two methods: laboratory preparation and industrial preparation. Anticipate, some people will say that the sentences are mixed.
Think of this.
Yu Yuanyong immediately made the decision:
"Attention all departments, we will try potassium ferricyanide first. If it doesn't work, we will consider other substances and start preparations immediately!"
As a well-known heavy industry group in China, Hanhua Factory naturally reserves a lot of potassium ferricyanide in the factory.
So it's very fast.
A newly prepared high-concentration potassium ferricyanide was placed 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 locking the wave peak.
Therefore, Yu Yuanyong deliberately adopted a detection method that combines Fourier transform infrared spectroscopy and Raman spectroscopy, which is very targeted.
Half an hour later.
Yu Yuanyong calculated the cycle of the rotating equipment, and the second round of experiments officially began.
"Dip hoo hoo hoo"
Another fifteen minutes passed.
The report results are officially released.
Yu Yuanyong took the report and glanced at it hastily, then his face lit up and he said to Xu Yun:
"Dr. Xu, the absorption peak shifted 40nm to the right after iron ion implantation, but the selective peaks at positions 530 and 1060 did not appear!"
"There is no doubt that your idea is right. The special liquid completely balances the interference in the feedback band!"
Hear this.
Xu Yun and Lin Zhenhua suddenly looked happy.
As Yu Yuanyong said.
This report basically confirms Xu Yun or Lao Su's idea, which means that transition metal catalysis is no longer an insurmountable obstacle.
As early as when they came to the laboratory, Yu Yuanyong introduced that their team had overcome some pre-existing technical obstacles and was stuck at the molecular sieve step.
After passing the molecular sieve, all that remains is the equipment problem of directional cyclization.
True.
Directional circularization is the final barrier, and may be more difficult than all the previous links combined.
But at least as far as the whole situation is concerned.
Having only one big problem to solve is definitely many times better than having a bunch of problems left.
It's like an online game.
Before officially attacking the wave boss, most players will first clear out the elite mobs and then focus on the single target of the fire wave boss.
Of course.
Before launching the final general attack, Yu Yuanyong and the others still had one problem to solve:
That's how you adapt a transition metal to the lowest cost metal, lanthanum.
However, this problem belongs to the category of pure industrial optimization and is beyond the capabilities of Xu Yun and others.
In addition, specific optimization will not produce results in a short time, it will take at least two days.
So after a simple handover.
Xu Yun and his party temporarily left the laboratory and were taken to the guest house of Hanhua Group by Zhao Haiyang.
The guest house of Hanhua Group is a newly renovated eight-story building. The interior decoration is not luxurious, but it looks quite grand.
The specification of a single room in the guest house is a 1.8-meter large bed. There is no bathtub in the bathroom. In addition to some basic facilities, there is only a desk in the room.
The curtains in the house are electric, and there is also a Xiaodu on the bedside table that provides voice assistance.
At the same time, as Lin Zhenhua said before, the sound insulation effect of the room is extremely excellent:
Xu Yun played a recording of snoring in the next room that a friend gave him to ward off evil spirits, but found that the sound could not be transmitted at all.
all in all.
It can be considered a standard four-star specification.
However, Xu Yun did not choose to take a shower and 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.
