Title: Hiroshi Matsumoto: A Pioneer in Chemical Innovations
Introduction
Hiroshi Matsumoto, an accomplished inventor hailing from Ageo, Japan, has made significant contributions to the field of chemistry with his innovative patents. With a total of two patents to his name, Matsumoto has developed groundbreaking solutions that address both industrial and agricultural needs.
Latest Patents
Matsumoto's recent inventions include "High-purity lanthanum isoproxide and a process for producing the same." This invention provides a true La(OiPr) which is preferable as a starting material for an asymmetric synthesis catalyst. The process involves reacting anhydrous lanthanum chloride (LaCl) with potassium isopropoxide (K(OiPr)) in a mixed solvent of isopropanol and toluene. Upon distilling away the isopropanol, the solvent is replaced entirely with toluene, followed by decanting and filtering the solution to yield a transparent filtrate. The final product of high-purity La(OiPr) is obtained through vacuum drying and heating, achieving an impressive yield of 77%. The specifications of this compound indicate that the lanthanum content is 97 to 103% of the theoretical amount, with minimal impurities, showcasing the efficiency of Matsumoto's method.
Another notable patent is focused on "2-Hydroxy benzamide derivatives and use thereof as a fungicide." This compound, characterized by a specific formula, has varied functional groups that allow it to serve effectively as a fungicide. Its versatility in terms of structural variations enables potential applications in agricultural chemistry.
