Title: Innovations of Yingqi Xia in Vitamin B1 Preparation
Introduction
Yingqi Xia is an accomplished inventor based in Shanghai, China. He has made significant contributions to the field of chemistry, particularly in the preparation of essential vitamins. His innovative methods have the potential to enhance the efficiency of vitamin production.
Latest Patents
Yingqi Xia holds a patent for a full continuous-flow preparation method of vitamin B1. This method involves several key steps: First, 3-chloro-4-oxopentyl acetate, 2-methyl-4-amino-5-(aminomethyl) pyrimidine, and carbon disulfide are fed into a first continuous-flow reactor for addition. Next, the reaction mixture flows into a first continuous filtration and reaction device to collect a filter cake. The filter cake is then subjected to cyclization with hydrochloric acid solution. Following this, the reaction mixture and an aqueous inorganic base solution are transported to a micromixer and a second continuous-flow reactor for hydrolysis to obtain thiothiamine. The thiothiamine is then moved to a third continuous-flow reactor with hydrogen peroxide for oxidation to produce thiamine sulfate. Finally, the thiamine sulfate enters a second continuous filtration and reaction device for filtration, where it is subjected to a reaction with an organic hydrochloric acid solution, followed by filtration and drying to obtain vitamin B.
