Title: Motomu Ohkita: Innovator in Acrylic Chemistry
Introduction
Motomu Ohkita is a notable inventor based in Otake, Japan. He has made significant contributions to the field of acrylic chemistry, holding a total of 3 patents. His work focuses on processes that enhance the production of high-purity (meth)acrylic compounds.
Latest Patents
Ohkita's latest patents include innovative methods for producing (meth)acrylic anhydride and (meth)acrylic esters. In his first patent, he describes a process where (meth)acrylic acid is reacted with a fatty acid anhydride. The resultant reaction mixture is then neutralized and washed with an aqueous alkaline solution, maintaining a pH of 7.5 to 13.5. This method allows for the industrial production of high-purity (meth)acrylic anhydride while avoiding polymerization. In his second patent, he details a process where the (meth)acrylic anhydride is reacted with a secondary or tertiary alcohol in the presence of a basic compound. This reaction occurs in water at 25°C, where the basic compound has an acidity (pKa) of 11 or lower, resulting in a high yield of high-purity (meth)acrylic ester.
