Professor Huang is in his fifties, gentle and elegant. He graduated from the Chemistry Department of Peking University in the late 1950s and is now the dean of the Chemistry Department of a key domestic university. His major is organic synthesis and he has made great achievements in the field of drug synthesis. He has published many articles. An influential paper, its scientific research achievements have twice won the second prize of the provincial and ministerial level Science and Technology Progress Award. It is said that the last time the Chinese Academy of Sciences selected academic members, Professor Huang was only one vote short of being selected.
As a well-known expert in the industry, Professor Huang was invited to attend the pharmaceutical technology seminar this time. He did not expect to meet a young scientific and technological talent like Fang Hanmin. On the first day when he read out the paper, Fang Hanmin impressed Professor Huang very deeply. What he did yesterday afternoon The report on the development trend of pharmaceutical technology made Professor Huang even more impressed by him.
Although they ate at the same table these two nights, Professor Huang had almost no communication with Fang Hanmin. He believed that there were too many people talking at the dinner table and it was not suitable for discussing technical issues.
Just now, Professor Huang saw Fang Hanmin sitting alone and leisurely from a distance. He immediately came over and wanted to take this opportunity to have an in-depth communication with Fang Hanmin.
Of course Fang Hanmin had to take Lao Huang seriously. He sat upright and said, "Professor Huang, you are a well-known expert in the industry. I am very honored and a bit flattered to be able to chat with you."
"Chief Fang, there are only you and me here, so don't be polite to me. We don't have famous experts in the industry, so you don't need to be flattered. Isn't it good that we sit together and discuss technical issues at will?" Professor Huang wanted to make the atmosphere more casual.
"Professor Huang is very approachable and I am very touched, but I don't know what issue Professor Huang wants to talk about?"
"Let's start with the paper you read." Lao Huang picked up the tea cup and took a sip.
"Oh, my paper...what can we talk about?" Fang Hanmin was confused.
"Actually, I have carefully studied all four papers you published in the magazine "Pharmaceutical Technology". The writing level of the papers is of course very high, but this is not the topic we want to talk about. The technical level involved in the papers has reached the level of Pharmaceutical Technology. Unprecedented, this is not only my evaluation, but also affirmed by Professor Fei, and it is also supported by winning the first prize of the provincial Science and Technology Progress Award."
"But what does this have to do with the paper I'm reading?"
Professor Huang nodded slightly, "Chief Fang, if I guess correctly, the paper you read yesterday is not the core of your technology. The focus of your technology should be the second of the four papers, which is Is it the preparation of palladium carbon catalyst?"
Fang Hanmin smiled and said, "Professor Huang is indeed a famous expert in the industry. He can see the essence of things at a glance. It is no wonder that catalysts are becoming more and more important in the field of organic synthesis, and the application of catalyst technology in the pharmaceutical industry has great potential." potential."
Lao Huang agreed with Fang Hanmin, "An efficient catalyst can not only improve the selectivity of organic reactions, shorten reaction time, reduce production costs, but also minimize the generation of by-products. For the pharmaceutical industry, this is conducive to improving the quality of raw materials." It is of great significance to improve the purity of the medicine and thereby reduce the toxic and side effects of the medicine!”
"Professor Huang is an expert in this field, and you have the best say in this field."
"However, the paper you read at the seminar did not choose the one related to the preparation method of palladium-carbon catalyst. The preparation method of palladium-carbon catalyst is the core of hydrogenation reduction technology. Is Section Chief Fang worried? What?"
"This..." Fang Hanmin thought for a moment, "Professor Huang, if you are interested in the preparation method of palladium carbon catalyst, you can read the paper in the magazine "Pharmaceutical Technology", so we don't have anything concern."
Lao Huang smiled and waved his hand, "Chief Fang, that's completely different! After all, only a few people can see that paper in a magazine, and even fewer people can understand it. If you are at the seminar By reading that paper in person, not only will more people know about it, but through your explanation, more people will know about the preparation method of palladium-on-carbon catalysts, which has a completely different meaning. So I think you still have concerns."
Although Fang Hanmin did not admit his concerns verbally, Lao Huang guessed right. The preparation of palladium carbon catalyst is a very cutting-edge technology. Even if it does not involve the interests of Red Star Pharmaceutical Factory, from Fang Hanmin's own perspective, he would not ignore it. All technical details will be made public without reservation. After all, time travelers have experienced the 21st century and have long been aware of intellectual property protection.
When he received the invitation to participate in the conference, the organizer of the conference asked Fang Hanmin to choose a paper to be read at the seminar. He considered it again and again, and he could choose any other content, except for the paper on the preparation method of palladium-carbon catalyst.
Even though Lao Huang guessed his thoughts, Fang Hanmin didn't feel too embarrassed. He prevaricated: "Professor Huang, what you said may make sense, but we also have difficulties. There are some things that I can't decide by myself."
"Chief Fang, I understand your difficulties. As a middle-level cadre, he is restricted by the factory-level leadership and lacks freedom in his work. Okay, let's not talk about this issue. Do you mind talking to me about the palladium-carbon catalyst?"
"Talk about palladium carbon catalyst? Of course you don't mind. Do you plan to talk about its application prospects? The scope is wide, such as petroleum processing, fine chemicals, and pharmaceutical synthesis."
Fang Hanmin was familiar with the topic and deliberately deviated from the topic. Lao Huang interrupted him and said, "Chief Fang, I also know that the application prospects of palladium-carbon catalysts are very broad. Let's not talk about this."
"Then what do you want to talk about?"
"Let's talk about the preparation of palladium-on-carbon catalysts. I believe that Section Chief Fang must be very experienced. Is the preparation process of this kind of catalyst that uses precious metals as raw materials very strict? Otherwise, if there is a waste product, the loss will be huge. "
Fang Hanmin finally knew the purpose of Professor Huang's chat with him. It turned out that Huang was very optimistic about the application prospects of palladium-carbon catalysts, so he had a great interest in this kind of catalyst. However, the preparation of palladium-on-carbon catalysts is an insurmountable hurdle.
When Professor Huang saw Fang Hanmin's paper in the magazine "Pharmaceutical Technology", he was very encouraged. However, after reading it carefully, he found that the paper was relatively general about the preparation of palladium carbon catalyst, especially the formula and production process. The explanation is rather vague. Because it involves precious metal raw materials, there is little opportunity for imitators to try and make mistakes. Therefore, Huang failed to find what he wanted in Fang Hanmin's paper.
I originally thought that Fang Hanmin, who was invited to participate in the seminar, would read a paper on the preparation of palladium carbon catalysts. Professor Huang planned to discuss the preparation process and formula of the catalyst in detail with him during the interactive session. When he learned that Fang Hanmin read the title of the paper, Professor Huang was disappointed again , and decided to find an opportunity to chat with Fang Hanmin about the details of the catalyst preparation process before the meeting ended.
Fang Hanmin felt a little rude if he refused to discuss this issue with Professor Huang. After all, Huang is a senior in the industry and has high moral standing. If word spread, the outside world will think that Fang Hanmin has no respect for his superiors. It does not matter if he is suppressed. The key is that he is afraid of causing harm to the Red Star Pharmaceutical Factory. adversely affect the industry.
Since he could not refuse Lao Huang's request, Fang Hanmin had no choice but to agree, "Professor Huang, the palladium carbon catalyst is a solid catalyst. The preparation process has a great impact on the performance of the catalyst. It can be said that every link is important. I wonder which link you are more concerned about. ?”
Because no substantive issues were involved, this was not said. However, this was Fang Hanmin’s strategy. Although he agreed to exchange palladium carbon catalyst preparation methods with Lao Huang, it did not mean that the technical secrets and process conditions would be completely disclosed to him. .
It’s not that Fang Hanmin is conservative, this is related to the survival space of Red Star Pharmaceutical Factory, because once the outside world masters this technology, the paracetamol API produced in the second workshop of Red Star Pharmaceutical Factory will instantly lose its competitive advantage.
Lao Huang heard clearly that Fang Hanmin's words were completely playing Tai Chi, which made it difficult for him to find the focus, but he could not find any major faults.
The preparation process of palladium carbon catalyst involves many factors such as raw material formula, mixing uniformity, metal deposition, temperature, pressure, time, particle size and strength. Any carelessness in any link will adversely affect the catalytic performance. Lao Huang wants to master the complex preparation process through just one chat, which is simply fantastic!
In addition, every step of the preparation process requires very skilled techniques. Even if Fang Hanmin explains it clearly, if you have not seen it with your own eyes and have very skilled operators, you still cannot make a palladium carbon catalyst with excellent performance.
However, now that he has opened this door, no matter how many problems he faces, Lao Huang cannot get nothing. So, he chose a more complicated link and asked: "Let's talk about the metal deposition process. What do you think we should pay attention to?"
Worthy of being a first-class expert in the industry, Fang Hanmin believes that the entry point chosen by Huang is very important, but he will have reservations, "There are also many factors involved in metal deposition, such as liquidus temperature, concentration, feeding speed, stirring speed, deposition time, etc. etc. This requires not only skilled operation, but also considerable experience. In short, skilled operating techniques and rich operating experience are both indispensable.”
Professor Huang is undoubtedly one of the few experts in the country when it comes to theory, but this is not necessarily the case in actual operation. Regardless of operating techniques and experience, it requires continuous practice and long-term accumulation.
Fang Hanmin benefited a lot from this aspect while studying for a PhD in Oxford and working as a project director at the New Drug Creation Center of RGP Company. Therefore, he dared to lead a group of novices who had never seen the world to prepare palladium in the simple laboratory of the Red Star Pharmaceutical Factory. Carbon catalyst.
Due to limited conditions, even though Professor Huang is already in his fifties and has worked in scientific research and teaching positions for more than 20 years, he has much fewer opportunities to conduct experiments himself than Fang Hanmin.
After chatting for nearly two hours, although he had some reservations, Fang Hanmin also introduced the preparation process of the palladium carbon catalyst from beginning to end, with some details in some places. Professor Huang heard a general idea, but if he was asked to do it himself, he still had no confidence in himself. In fact, when it comes to practical issues, the core issues cannot be solved by just talking on paper.
Seeing several participants milling around, Professor Huang realized something, "The conference team has arranged for everyone to interact today. These people may want to discuss issues with you."
"Professor Huang, you are an expert. They may have something to consult with you."
Lao Huang turned around and asked, "Looking at you guys hanging around here for so long, are you okay?"
"If Teacher Fang is free, we would like to ask him some questions."
"Did you see that? I'm looking for you. Okay, that's it for today. I hope we can keep in touch with you in the future. I hope Section Chief Fang won't refuse to discuss technical issues with me." After saying that, Professor Huang picked up the water glass and held it. The information left.
