Title: Innovations of Toshio Ashitani: Pioneering Patents in Aluminum Chemistry
Introduction: Toshio Ashitani, an accomplished inventor based in Niihama, Japan, has made significant contributions to the field of chemical engineering, particularly in the production of aluminum compounds. With two patents to his name, Toshio's work showcases his expertise and innovative spirit in optimizing processes for preparing aluminum sulfate and alumina.
Latest Patents: Toshio Ashitani's latest patents reflect his dedication to advancing aluminum chemistry. The first patent introduces a novel process for preparing aluminum sulfate. This method reduces the color of the aluminum sulfate produced by carefully adjusting the concentration of hydrogen peroxide in sulfuric acid to 0.1% by weight or less, followed by the contact of the sulfuric acid with an alumina-containing compound. The second patent focuses on the preparation of alumina, wherein an aqueous slurry of aluminum hydroxide particles smaller than 5 micrometers, with a viscosity of about 100-1000 centipoises, is spray-dried. The dried powders are then calcined to generate alumina powders characterized by a sharp particle size distribution, making them suitable for electronic, abrasive, and refractory applications.
