Title: Shigeharu Iida: Innovator in Fluorinated Compounds
Introduction
Shigeharu Iida is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of chemistry, particularly in the development of fluorinated compounds. With a total of 2 patents, Iida's work has implications for various industrial applications.
Latest Patents
Iida's latest patents include a method of preparing (perfluoroalkyl) ethyl acrylic esters and a process for preparing di(fluoroalkyl containing group-substituted alkyl). The first patent describes a method where a polyfluoroalkyl iodide is reacted with a (meth)acrylic acid metal salt to form a corresponding polyfluoroalkyl (meth)acrylate ester. This ester is then separated from the reaction product through evaporation, allowing for its recovery. The method is notable for its efficiency, as it avoids the introduction of water during the reaction. The second patent outlines a process for hydrolyzing a mono-sec.- or tert.-alkyl (di(fluoroalkyl containing group-substituted alkyl) phosphate with a base, resulting in a di(fluoroalkyl containing group-substituted alkyl) phosphate salt. This compound is useful as a surface-active agent and for creating water- and oil-repellent properties in fibers or papers.
