Title: Masanori Tokuda: Innovator in Hydroxyalkyl (Meth)Acrylate Production

Introduction

Masanori Tokuda is a notable inventor based in Hatsukaichi, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of hydroxyalkyl (meth)acrylates and methacrylic esters. With a total of three patents to his name, Tokuda's work demonstrates a commitment to enhancing production efficiency and reducing environmental impact.

Latest Patents

One of Tokuda's latest patents is a method for producing hydroxyalkyl (meth)acrylate. This innovative method emphasizes high production efficiency while minimizing the burden on production systems. The process involves a reaction step where (meth)acrylic acid is reacted with an alkylene oxide in a reactor. This is followed by a deaeration step that reduces pressure in the reactor to vaporize and remove unreacted alkylene oxide, optimizing the stirring revolutions during the process.

Another significant patent is a process for producing methacrylic ester. This method involves an ester-exchange reaction between methyl methacrylate and an alcohol or phenol. By removing by-product methanol as an azeotropic mixture with methyl methacrylate under reflux conditions, this process achieves good productivity through careful control of the reflux ratio.
