Title: Innovations of Mitsuhiro Kouno in Polyester and Sorbic Acid Production
Introduction
Mitsuhiro Kouno is a notable inventor based in Arai, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of polyesters and sorbic acid. With a total of 9 patents to his name, Kouno's work has had a substantial impact on the industry.
Latest Patents
Kouno's latest patents include innovative processes for producing polyesters and sorbic acid. The process for producing polyester involves supplying crotonaldehyde with a purity of 95% by weight or more to a reaction system where ketene reacts with crotonaldehyde. This method allows for the recovery and recycling of unreacted crotonaldehyde from the reaction mixture. The process also specifies that the α-vinylcrotonaldehyde content should be less than 0.5% by weight, and the paraldehyde content should be less than 5% by weight. Additionally, by decomposing the polyester with hydrochloric acid, a high-quality sorbic acid can be efficiently obtained. The process for preparing sorbic acid involves decomposing the polyester at temperatures of 100°C or less with hydrochloric acid, which is controlled by adding hydrochloric acid at a lower temperature. This innovative approach allows for a high yield of sorbic acid in a short time.
