Title: Tsutomu Nanmyo: Innovator in Fluorochemical Production
Introduction
Tsutomu Nanmyo is a prominent inventor based in Ube, Japan. He has made significant contributions to the field of fluorochemical production, holding a total of 5 patents. His innovative methods have advanced the efficiency and purity of chemical processes.
Latest Patents
One of his latest patents is the "Preparation method for perfluoroalkane sulfinate." This method involves obtaining an alkali metal perfluoroalkanesulfinate by reacting a perfluoroalkanesulfonyl halide with a sulfur-containing reducing agent in the presence of water. The process allows for the concentration of the reaction liquid, leading to the precipitation and removal of inorganic salts, which are impurities. The resulting filtrate can then be concentrated and dried to obtain high-purity alkali metal perfluorosulfinate, eliminating the need for organic solvents and significantly reducing waste.
Another notable patent is the "Fluoroalkanesulfonic acid production method." This method includes reacting concentrated sulfuric acid and/or fuming sulfuric acid with a fluoroalkanesulfonate to achieve acid decomposition. The process results in a reaction mixture containing fluoroalkanesulfonic acid and a sulfur component. By adding an oxidizing agent and conducting distillation, high-purity fluoroalkanesulfonic acid can be efficiently obtained, reducing the sulfur component in the process.
