Title: Jeong-Woo Yoo: Innovator in Epoxide and Glycerol Carbonate Production
Introduction
Jeong-Woo Yoo is a notable inventor based in Toulouse, France. He has made significant contributions to the field of chemical engineering, particularly in the production of epoxides and glycerol carbonate. With two patents to his name, Yoo's work showcases innovative methods that enhance efficiency and purity in chemical processes.
Latest Patents
Yoo's latest patents include a method for producing an epoxide, specifically glycidol. This invention involves heating a cyclic organic carbonate, such as glycerol carbonate, under reduced pressure to facilitate a reaction that converts the carbonate ring into an epoxide ring. The process is conducted in a solid/liquid system with the presence of a polyol and a solid catalyst, which can be a type A zeolite or γ-alumina. This continuous method allows for the epoxide to be formed in a single step, with the epoxide being extracted as vapor, simplifying the separation from carbon dioxide.
Another significant patent by Yoo is a method for preparing glycerol carbonate. This method entails the reaction of urea and glycerol at temperatures ranging from 90°C to 220°C, utilizing a catalyst with Lewis acid sites. The invention enables the production of glycerol carbonate in a highly pure state through a catalytic carbamoylation/carbonation reaction, achieved under economical conditions.
