| titleOfInvention | A kind of full continuous flow preparation method of L-carnitine |
| abstract | The invention belongs to the technical field of organic chemical engineering, in particular to a full continuous flow preparation method of levocarnitine. In the present invention, the reaction solution of chlorine and diketene is mixed through a micro-mixer, and then transported into a micro-channel reactor for continuous chlorination and esterification to obtain 4-chloroacetoacetate; then, the reaction solution is continuously mixed with reduction The enzyme is simultaneously transported to the second micro-mixer and the micro-channel reactor, and continuous enzymatic catalytic reaction is carried out to obtain ( R )-4-chloro-3-hydroxybutyrate; the reaction solution is continuously transported to the third In the micro-mixer and the micro-channel reactor, continuous substitution and hydrolysis reactions are carried out; finally, the final product L-carnitine is obtained through the continuous desalination and continuous concentration system. Compared with the traditional batch kettle type synthesis method, the method of the invention has the advantages of good safety, short reaction time, high degree of automation, high process continuous efficiency, high space-time yield, low energy consumption and easy industrial scale-up application. |
