Latest Patents

Koshida's latest patents focus on improving the manufacturing process of alkylene oxide adducts. One of his key innovations involves a method where the reaction mixture, which includes the alkylene oxide adduct, unreacted alcohol, acid catalyst residue, carbonyl compounds, and hydrocarbons, is treated to remove unreacted alcohol for recycling. This process aims to prevent the accumulation of carbonyl compounds and hydrocarbons that are difficult to distill from the recycled alcohol. To achieve this, a portion of the recycled alcohol is esterified with boric acid, and the resulting esterification mixture is distilled to eliminate volatile components. The borate ester obtained is then hydrolyzed to recover the alcohol, which is recycled back into the adduct formation step.
