Latest Patents

Sheng Yu holds a patent for a method titled "Method for preparing sucralose-6-acetate in biphasic liquid-liquid system." This invention outlines a process that involves slowly adding an inert non-polar solvent containing a chlorinating agent to an N,N-dimethyl formamide (DMF) solution of sucrose-6-acetate. The method requires reacting the biphasic liquid-liquid mixture at a specific temperature for 9-20 hours. After the reaction, the system is cooled to room temperature, allowing the solution to settle into layers. The upper layer consists of an inert non-polar solvent, while the lower layer contains the DMF solution with the product. The process includes hydrolyzing, neutralizing, and filtering the lower layer to obtain a filtrate, which is then concentrated and dissolved in water. The final product is extracted using ethyl acetate and crystallization. This method boasts a high product yield and significantly reduces the decomposition of DMF, leading to lower production costs.
