Title: Innovations of Zheng Chai in Surface Active Agents
Introduction
Zheng Chai is an accomplished inventor based in Spring, TX (US). He has made significant contributions to the field of surface active agents, particularly those derived from biodiesel-based alkylated aromatic compounds. With a total of 2 patents to his name, his work has implications for various industrial applications.
Latest Patents
Zheng Chai's latest patents focus on the development of surface active agents that comprise arylated methyl esters of fatty acids derived from biodiesel or triglyceride sources. The process involves condensing fatty acid mixtures into methyl esters, which are then alkylated with aromatic substituents under Friedel-Crafts conditions. The alkylated methyl esters can be further alkoxylated using catalysts derived from fatty acids, alkaline earth salts, and strong acids. This results in nonionic surfactants that may also be sulfonated to produce anionic surfactants. Additionally, the alkylated methyl esters can be directly sulfonated to create another class of anionic surfactants.
