Title: Hitoyuki Araki: Innovator in Chemical Processes
Introduction
Hitoyuki Araki is a notable inventor based in Jouetsu, Japan. He has made significant contributions to the field of chemical engineering, particularly in the development of methods for synthesizing important chemical compounds. With a total of 2 patents to his name, Araki continues to push the boundaries of innovation in his industry.
Latest Patents
Araki's latest patents include a method and apparatus for preparing 3-[N-(2-aminoethyl)]aminopropylalkoxysilane. This invention allows for high yields by reacting 3-chloropropylalkoxysilane with ethylene diamine. The process involves a distillation pot where ethylene diamine is heated above its boiling point, evaporating it for condensation into a liquid. This liquid is then mixed with 3-chloropropylalkoxysilane in a specific molar ratio to facilitate the reaction. The apparatus designed for this process includes a distillation pot, a reflux condenser, a feed means, and a reactor, all connected to form a recirculating system.
Another significant patent is a process for preparing methyl chloride by reacting hydrogen chloride with methanol in a liquid-phase non-catalytic reaction. This innovative method employs a reaction system comprising a reactor and two distillation columns, each operating under different pressures. This setup greatly increases the space-time yield and conversion rates while minimizing the production of dimethyl ether as a byproduct. The process effectively utilizes hydrogen chloride gas and diluted hydrochloric acid, which are often produced as waste in various chemical processes.
