Title: Yougui Zhou: Innovator in Sucrose Chemistry
Introduction
Yougui Zhou is a prominent inventor based in Shaoxing, China. He has made significant contributions to the field of sucrose chemistry, holding a total of 3 patents. His innovative methods have improved the efficiency and selectivity of chemical processes involving sucrose derivatives.
Latest Patents
One of his latest patents is a method for synthesizing sucrose-6-ester. This method involves contacting an organic phosphine compound with sucrose and an organic tin compound in the presence of a polar aprotic solvent. The process includes removing water to obtain a reaction liquid containing a tin-sucrose adduct, which is then treated with an acid anhydride compound to prepare the sucrose-6-ester. This method significantly enhances the reaction conversion rate and selectivity, making it suitable for industrial applications.
Another notable patent is the method for preparing sucralose-6-acetate in a biphasic liquid-liquid system. This method entails slowly adding an inert non-polar solvent containing a chlorinating agent to a DMF solution of sucrose-6-acetate. The biphasic mixture is reacted at a controlled temperature for 9-20 hours, followed by cooling and settling to separate the product layers. The process yields a high product output while minimizing the decomposition of DMF, thus reducing costs.
