Title: Sadao Toyoda: Innovator in Detergent and Chemical Processes
Introduction
Sadao Toyoda is a notable inventor based in Funabashi, Japan. He has made significant contributions to the field of chemical processes, particularly in the development of improved granular detergents and the recovery of alkyl sulfonic acids. With a total of 3 patents to his name, Toyoda's work has had a meaningful impact on the industry.
Latest Patents
One of Toyoda's latest patents is a process for improving granular detergents. This innovative method enhances properties such as caking preventability, fluidity, and particle hardness. The process involves spray-coating a coating agent consisting of silicates, sulfates, carbonates, and hydroxides of alkali metals, along with polyvalent metal sulfates, onto granular detergent particles. This is done while the detergent is in a fluid state, resulting in a coating film of a water-insoluble or poorly water-soluble substance.
Another significant patent by Toyoda is a process for recovering alkyl sulfonic acid from a photosulfoxidation reaction mixture of an alkane. This process includes separating a major portion of the unreacted alkane by settling, followed by steam-distillation to remove the remaining unreacted alkane and sulfur dioxide. The sulfuric acid is then separated without heating, allowing for the recovery of alkyl sulfonic acids.
