Chapter 172 Talk
Amidst everyone's unfinished and unembarrassed flattery, Shen Guanglin left the stage gloriously.

He really doesn't need to be too anxious.

The initiative is in your own hands, after all, it is a rare commodity to live in.

Chiral catalysis has always been a hot topic of the times, and the heat value has been as high as 99 for a long time, which is only one degree away from the boiling point.

The frequency of researchers' disturbance is very high, and any opportunity can cause a volcanic eruption.

As for the research on chiral catalysis, no matter at what point in time, as long as there is a big progress, it is almost a global focus event.

The two core areas of chiral catalysis are chiral ligands and chiral catalysts.

Some people in later generations have summarized and sorted out the process of chiral catalysis.

In fact, chiral catalysis can be roughly divided into 8 types in terms of working mechanism, and each has its own characteristics and far-reaching influence.

Takeda's own chemistry lab studies complexes of BINAP with the metals rhodium and ruthenium.

This is also one of the most influential catalytic methods in the later world.

Even Ryoji Noyori later won the Nobel Prize for it.

The hydrogenation reaction of BINAP is indeed a big research topic, and many good articles can be produced.

But for Shen Guanglin, it is very difficult for him to conduct groundbreaking research in this area.

It's not that he can't do it, and it's not that domestic researchers don't work hard enough. It's just that rhodium and ruthenium are rare metals, very expensive, and the purity is not good.

Many scientific researches are also limited by objective conditions.

For example, a well-known metal vitamin in later generations is called indium. In fact, it is an associated mineral of zinc. 70% of the world's indium is produced in China, but foreign companies can actually deal with it.

Not to mention ballpoint pen refills, even the odorant added to natural gas, that is, ethanethiol, is actually imported.

Ethanthiol is known as the most smelly substance, bar none.

When the air contains only one part per 500 billion of ethanethiol, its odor can be smelled.

The structural formula of ethanethiol is very simple, that is, the oxygen atom in ethanol is replaced by sulfur.

It is not difficult to prepare it in the laboratory, and it can be obtained by the reaction of thiourea and bromoethane.

However, there are so many natural gas companies in China, but none of them are willing to produce this thing.

This thing has been obtained in China by the reaction of sodium ethyl sulfate and sodium hydrosulfide.

But its shortcomings are also obvious: long lines, low yield, and high requirements for raw materials, such as sodium ethyl sulfate is prepared with absolute ethanol and oleum.

The ethanethiol used for commercial purposes in foreign countries is obtained by gas-phase catalytic reaction of ethanol and hydrogen sulfide under normal pressure, and the catalyst uses activated alumina as a carrier, impregnated with tungstic acid or sodium tungstate.

If Shen Guanglin studied chemistry, he could cultivate a company with this production method.

Back to chiral catalysis.

To be honest, even Shen Guanglin was a little envious of Ryoji Noyori's work, but it was a pity that he came into contact with this field too late.

Up to now, there is only a little leftovers in this field that have not been dealt with.

But I am not proficient in it, so I can only fool around pretending to be profound.

After all, BINAP ligands can solve the problem of efficient and highly selective hydrogenation of simple aryl ketones, which is the most mainstream direction of chiral catalysis.

In a single practice, the TOF data of this catalyst is as high as 60 times per second, which means that one catalyst molecule can catalyze the conversion of 60 substrate molecules per second.

What a powerful catalyst!

However, for chiral catalysis, there are too many hotspots to look for: metal complex chiral catalysis, biochiral catalysis, organic small molecule chiral catalysis, and supported homogeneous chiral catalysis. It can leverage the market size of billions.

There is no need to buy lottery tickets to rely on the prophet to make money. As long as you are ahead of others, as long as you don't use the methods recorded in the criminal law, the money will come naturally.

Shen Guanglin felt that it was a bit difficult to climb the technology tree by himself, but he could also take some benefits from others by relying on deception.

In this way, Shen Guanglin gave Takeda an unfathomable and simple image.

What is unfathomable is technical strength and genius sense of smell, and what is simple is how to deal with people and behave in the world.

This is the persona created by Shen Guanglin for himself. A person who is too shrewd has no friends, and just the right amount of shrewdness in the mediocrity is the way to win.

Shen Guanglin was eating at the staff restaurant of Takeda Company that day, and he felt that he needed to study the company in depth.

Then, by chance, he ran into an old acquaintance, the delegation from Jin City.

It is said that their affairs were not handled very smoothly, and I hope Teacher Shen can help to say something good.

Shen Guanglin didn't care about these, but was thinking about how to publish his breakthrough in the nanometer field in newspapers.

The newspaper with the largest circulation in Fuso is "Sankei Shimbun". This newspaper has a high reputation and meets Shen Guanglin's expectations.

If he wanted to publish his thesis in such a newspaper, he had to wait at DJ.

It is estimated that Makoto Kobayashi will not be able to help much in this matter, and in the end it will still fall on Takeda to seek a breakthrough.

Shen Guanglin goes to bathe, sing, dance and dance every day
Xiao Lincheng and Li Li didn't have time to find him, but someone from the office came and said they wanted to invite him as a guest.

The second brother was picked up by the senior secretary of the office. When Shen Guanglin got into the car, he realized that there was another person sitting in the back seat.

What a coincidence, Shen Guanglin knows this person, he is the leader of the pharmaceutical company.

"Xiao Shen, hello, Professor Shen, we meet again, I'm Xingqin, Qin Bufan, and I'm the deputy director of the No. [-] Pharmaceutical Factory in Jin City." The other party finally introduced himself.

He is also a familiar character, walking and talking all the way.

Basically, I hope that Shen Guanglin can facilitate the negotiation, otherwise they will be left behind when they return to China.

Shen Guanglin didn't promise anything, he didn't even know what they wanted him for.

"The last time Mr. Shen came to DJ, he didn't go to the office as a guest. The leader really wanted to get to know you, so he specially told us to invite you, and the office is making dumplings."

Making dumplings is the cheapest way to entertain guests from China.

But the secretary added drama to himself, making himself feel very moved. It is rare to eat authentic dumplings in foreign countries.

"Oh, I said earlier that I would bring some for you. When I came from the capital the day before yesterday, I ate dumplings stuffed with beef. It tasted pretty good."

Shen Guanglin smiled, they were the only ones who were more emotional.

I just came back from China, so how could I miss the taste of my hometown? I am not an international student who does not smoke all the year round.

The car got onto the main road, merged into traffic, and arrived at the office in no time.

Mr. Director of the office is waiting for them at the gate.

This is also the driver's credit. He knew the code word and honked the horn in advance.

In the office, the leader said seriously, "Comrade Shen Guanglin, we have something to ask you."

"Please tell me." Shen Guanglin looked at the battle, a little puzzled.

Leader Qin coughed, "Should I avoid it?"

"No, you should listen to it too, if there is something, change it, if not, then crown it."

"Teacher Shen Guanglin, I heard that the last time you came to Fusang, Takeda Corporation donated a huge sum of money to you, but you did not report and hand it in."
