Into Unscientific

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

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

"Hiss, it seems really possible?"

Considering that some students may not understand the nature of the 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 feed port 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—for example, 30 seconds.

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

At this time, someone proposed a solution:

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

Wouldn't it be nice if the feed inlet could be raised to six centimeters for a few seconds whenever a five-centimeter giant cycle appeared?

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

At least within the acceptable range.

Although in today's practical operation, 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 of eight with his right hand, covering the front of his nose, and picked up the report from the table again with his left hand, and took a closer look at it.

Chemical intermediates.

As the word implies, it refers to some common intermediate substances in the chemical industry, which can be subdivided into 11 categories.

In addition to additives, chemicals and daily chemicals in these 11 categories.

Liquids such as reagents, paints and dyes are also included.

However, 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 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 portion of the salts are excluded.

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 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 looked at the result:

"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, and 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 ferric ion beams."

"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 lives 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.

Shortness of breath then begins and blood pressure rises.

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

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

As a result, symptoms such as cardiac arrest and multiple organ failure led to rapid death.

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 highly popular and not illegal substance.

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:

"Little Qian, 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 was talking about was a rare girl in the chemical industry. She had short hair and looked quite capable.

She clicked on the keyboard a few times, then quickly raised her head and said:

"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 calculations, 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.

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

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

It would be better to say that this is a laboratory preparation.

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. The method can be regarded as effective if the product can be obtained, 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-prejudgment, some people will say that the sentences are mixed.

Think here.

Even Yu Yuanyong made a decision:

"Attention all departments, let's try potassium ferricyanide first, and then consider other substances if it doesn't work, start preparing immediately!"

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

So soon.

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

At the same time, it is considered 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 - swoosh -"

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!"

I heard this.

Xu Yun and Lin Zhenhua immediately beamed with joy.

As Yu Yuanyong said.

This report basically affirmed Xu Yun's or Lao Su's thinking, which means that transition metal catalysis is no longer an insurmountable natural 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, only the equipment for directional cyclization remains.

Indeed.

Orientation ringization is the last barrier, and the difficulty may be higher than all the previous links combined.

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

It is certainly many times better to have only one big problem left to be solved than to have 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 transition metals to 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 party temporarily left the laboratory and were brought by Zhao Haiyang to the guest house of the Hanhua Group.

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 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 house 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 ears 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 didn't 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, and then took the vehicle prepared by Zhao Haiyang and drove to Yongcheng Railway Station.

The destination of the two of them is very clear:

Go to Zhenjiang first.

Then go to Wuzhou Mountain.

Arrived at last.

Su Song's tomb.
