Title: Yu Ohashi: Innovator in Ether Production
Introduction
Yu Ohashi is a notable inventor based in Ichihara, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of ethers. With a total of 2 patents to his name, Ohashi's work has advanced the methods used in this important area of chemistry.
Latest Patents
Ohashi's latest patents include a process for the production of ethers. This innovative method involves inserting an oxyalkylene group of an alkylene oxide into a chain-type ether compound that has at least one lower alkyl group. The reaction occurs in the presence of a catalyst created by mixing boron trifluoride and/or stannic chloride with an active-hydrogen compound, such as water or a lower aliphatic alcohol. This process notably reduces the formation of by-product dimer of the alkylene oxide, even when the charging ratio of the alkylene oxide to the chain-type ether is increased. Another significant patent is for the production of diethers. This process entails reacting an ether with at least one lower alkyl group with alkylene oxide in the presence of a heteropoly acid or its acidic salt. The preferred heteropoly acids and their acidic salts have a ratio of the hetero and coordinate atom of 1:6 and 1:12.
