Title: Masamichi Matsumoto: Innovator in Chemical Processes
Introduction
Masamichi Matsumoto is a notable inventor based in Kumagaya, Japan. He has made significant contributions to the field of chemistry, particularly in the development of high-purity chemical compounds. With a total of three patents to his name, Matsumoto's work has implications for various applications in materials science.
Latest Patents
Matsumoto's latest patents include a process for producing high-purity lanthanum isoproxide. This invention provides a reliable starting material for asymmetric synthesis catalysts. The process involves reacting anhydrous lanthanum chloride with potassium isopropoxide in a mixed solvent of isopropanol and toluene. The isopropanol is distilled away, allowing the reaction solution to be filtered, resulting in a transparent filtrate. The final product, high-purity La(OiPr), is obtained with a yield of 77%, featuring a La content of 97 to 103% of the theoretical value and minimal impurities.
Another significant patent is the process for producing bismuth tertiary amyloxide. This compound serves as a starting material for forming ferroelectric films and oxide superconductive films. The process entails reacting bismuth bromide with sodium or potassium tertiary amyloxide in a toluene solvent containing tetrahydrofuran. The byproduct is filtered out, and bismuth tertiary amyloxide is recovered through distillation under reduced pressure.
