    摘要： There is disclosed a process for making a mono-lithium salt of 5-sulfoisophthalic acid (LiSIPA) having less than 200 ppm sulfate. The process uses a reaction mixture of acetic acid, water, a lithium cation producing compound, and 5-sulfoisophthalic acid. The reaction mixture is heated to reflux, cooled, filtered and washed to obtain a high quality LiSIPA having less than 200 ppm sulfate. Also disclosed is a high quality mono-lithium salt of 5-sulfoisophthalic acid having less than 200 ppm sulfate.

    摘要： A surface active agent comprising an arylated methyl ester of a fatty acid, or mixture of fatty acids, derived from biodiesel or a triglyceride source is disclosed. The fatty acid mixture is condensed to methyl esters and alkylated with aromatic substituents under Friedel-Crafts conditions. The alkylated methyl esters may be alkoxylated using a catalyst derived from fatty acids, alkaline earth salts, and strong acids. The resulting nonionic surfactant may also be sulfonated to produce one class of anionic surfactants. The alkylated methyl esters may also be directly sulfonated to produce another class of anionic surfactants.
