Title: Louis N Kravetz: Innovator in Biodegradable Detergents
Introduction
Louis N Kravetz is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of chemistry, particularly in the development of biodegradable detergents. With a total of 12 patents to his name, Kravetz has established himself as a key figure in innovative chemical compositions.
Latest Patents
One of his latest patents focuses on highly branched primary alcohol compositions and the biodegradable detergents made from them. This invention provides a new branched primary alcohol composition and the sulfates thereof, which exhibit good cold water detergency and biodegradability. The branched primary alcohol composition has an average number of branches per chain of at least 0.7, containing at least 8 carbon atoms and both methyl and ethyl branches. Additionally, the composition may contain less than 0.5 atom % of quaternary carbon atoms, along with a significant number of ethyl branches and terminal isopropyl branches. The manufacturing process involves skeletally isomerizing an olefin feed with at least 7 carbon atoms, followed by conversion to an alcohol through hydroformylation, and ultimately sulfation to obtain a detergent surfactant. Useful catalysts for this process include zeolites with specific channel dimensions that facilitate the production of a variety of branches while ensuring biodegradability and effective detergency.
