I Am the President of the University

   Chapter 433 Mission!

  Several researchers who refuted Tian Ziang before looked at each other.

   Isn’t this true?

  One of them, Sun Jie, stood up with some disagreement.

  Although it is a little inconspicuous as a doctor of Wuhan University of Technology among the doctors of many prestigious universities, sometimes you can’t just look at the school.

  Wuhan University of Technology is only a 211 university, but in the subject of materials science and engineering, the Ministry of Education has an A+ rating. There are only three universities in the country that have achieved an A+ rating: Tsinghua University, Beijing University of Aeronautics and Astronautics, and Wuhan University of Technology.

  In the field of materials, Wuhan University of Technology is better than Zhejiang University, Harbin Institute of Technology, and Shanghai Jiaotong University.

   "Director, do you think the vacuum distillation method is feasible? What about the scientific basis?"

Sun Jie’s face was neither humble nor overbearing, and said calmly: “You often say that scientific research must be down to earth. You can have a certain degree of science fiction, but it must not be divorced from reality. The current academic circles generally recognize that the reduced pressure distillation method only proposes a solution, but there is no solution yet. Which team announced it had breached."

  Chen Chong raised his eyebrows, “Dr. Sun’s remarks are pretty good, but since they can be put forward, they can definitely be realized.”

"Professor Fang and I have been discussing this vacuum distillation method in the past two days." As he said, Chen Chong smiled at Fang Haosen, "Professor Fang, please explain to them this continuous distillation method to purify lactide. "

"good."

  Fang Haosen nodded, and then looked around the researchers in the entire laboratory. When he moved his eyes to Tian Ziang, he paused a little, and took a deep look at the other person.

  When communicating with Chen Chong before, the other party mentioned Tian Ziang several times. Today is really different.

  Guanghua University has a very high salary. Although its overall strength is not high, its scientific research personnel are not much lower than Chen Hao, a 985 university.

  Being able to put forward different opinions from others in such a bunch of doctors from prestigious universities, and it is consistent with Chen Chong and Fang Haosen's thinking...

  Only Tian Ziang alone!

   Before that, Chen Chong smiled with him and bet several people would mention this reduced pressure distillation method.

  Chen Chong guessed 2 people, and he guessed 1 person.

  He guessed right, but he also guessed wrong.

  He thought that this person would be Dr. Xia Yao, but he never expected that it would be Tian Ziang who had sprung up.

"Academic and industrial circles believe that vacuum distillation has large equipment investment and high technical requirements, which is difficult to achieve. But if you want to prepare lactide with high optical purity and high yield, vacuum distillation is the best choice! "

  Fang Haosen said with a faint smile: “The advantage of the distillation method is that it does not need to use other kinds of solvents, so as to ensure that the purification and refining process will not introduce new impurities, and the equipment is easy to large-scale and continuous production.”

  Sun Jie couldn’t help but ask, “Professor Fang, but you also said that distillation requires high technical requirements and is difficult to achieve, which is unrealistic!”

  "Tian Ziang, do you know who first proposed the continuous distillation and purification of lactide just mentioned?" Fang Haosen suddenly turned to Tian Ziang.

  It was Chen Chong who was on the side with a funny look.

  Some people in the crowd suddenly realized, and suddenly felt a little embarrassed.

   "Uh...I really don't remember this. What I saw is not the earliest version." Tian Ziang scratched his head, and said with some embarrassment.

   "This continuous distillation method for purifying lactide was first proposed by me." Fang Haosen said indifferently as if to say something inconspicuous.

  This was only mentioned in his spare time before. At that time, he had some ideas, but was delayed and forgotten by things in the school later.

   Now it’s Sun Jie’s turn to be embarrassed. After all, this is something from a few years ago, and he would forget it for a while. He didn’t expect the author to be in front of his own home.

"After discussing with Director Chen in the past few days, we have always believed that continuous distillation can be used to purify lactide in the purification process of lactide. As for the specific implementation, I will give you a good talk. "

  Fang Haosen's words, the ears of everyone underneath stood up, for fear of missing a word.

  Because this will be the most advanced technology in the field of lactide and even biodegradable materials.

  "Continuous distillation to purify lactide can adopt a three-tower process.

The vacuum operation of the first distillation tower removes low-boiling components at the top of the tower, the vacuum operation of the second distillation tower removes all meso-lactide at the top of the tower, and the vacuum operation of the third distillation tower obtains high purity at the top of the tower. Of lactide products, and the yield of lactide with a purity of more than 99% will be higher than 90%! "

  The purity is over 99%, and the lactide yield is higher than 90%!

   "hiss..."

  I don’t know who took a breath.

  But no one pays attention to this at this time, many people are still in shock!

  The composite solvent multiple recrystallization method mentioned by Xia Yao is a purification process commonly used in the industry. Because it is easier to operate, the yield is not high, only 35.4%.

  90% compared to 35.4%……

  This is nearly doubled!

  The reason why the current domestic production capacity of lactide is insufficient is that it is blocked by this purification process.

  The lactide yield of most biotech companies is only 30%-50%, and the process is not mature enough to even supply the current China market, let alone after the full implementation of the plastic restriction order next year.

  Even the industry leader NatureWorks, the other party’s published lactide yield is 78.6%, but the unpublished laboratory technology is estimated to have exceeded 80%.

  Sun Jie and a few researchers next to each other glanced at each other, their eyes were incredible.

  Sun Jie couldn’t help swallowing a ball of saliva. For Professor Fang Haosen, if it can be done, then...

  He opened his mouth, and said in a somewhat incredulous and trembling voice: "Well, isn't that in the field of lactide or even biodegradation, we will be able to overtake corners and become the world's leading level...?"

  This result is really terrible!

Originally, they only thought that if they break through the lactide technology within one month, and then further in-depth research, increase the production rate of lactide, and become the first in the domestic industry. The ultimate goal is to solve the shortage of domestic production capacity and rely on foreign imports. problem.

  And what Professor Fang Haosen said...

  This, this amount of information is too big!

  Not only can it solve the problems of foreign countries led by NatureWorks. It can also supply domestic polylactic acid raw materials (lactide) while counterattacking overseas to occupy the international market!

  You should know that among the few wealth codes in the future, there will be environmental protection!

  Environmental protection, elderly care, space exploration, energy...These are definitely one of the mainstreams in the future!

  And environmental protection is to eliminate the existing non-degradable materials, and at the same time increase the promotion of degradable materials.

  Polylactic acid (), as a new type of biodegradable material, is regarded as one of the loudest calls in academia and industry.

  At this time, after the harvest, everyone was shocked ~www.readwn.com~Chen Chong took two steps forward.

  He said loudly and loudly:

   "The principal said that our Guanghua University exists to solve the predicament."

   "Everyone, we can't be followers and run behind other people's ass. Because we are running out of time! What we need to do is things that ordinary people can't do. It is the technological frenzy that leads this era!"

  "On our shoulders are the expectations of 1.4 billion compatriots."

  Chen Chong clenched his fists in front of his chest, his eyes were heavy and his voice was passionate.

  "This is the mission of our Guanghua University!"

  Ps: Today is the author's festival! After all, the author is just a 300-month-old child. Taking advantage of today's holiday, everyone quickly call out the recommended and monthly tickets! (The author is super fierce. jpg)

  　 In the afternoon, codewords are easy to get sleepy... The egg hurts. This chapter has been written from five o'clock to the present, I am starving to death, and I go to dinner.

  　　 The next chapter should be between 10-11.
