Phosphorylation of epoxides

摘要

Process for the phosphorylation of epoxides, in particular of epoxidised fatty acids, and the use of the phosphorylation products for the production of lubricants. Phosphoric acid and its mono- and diesters react with epoxides with the formation of phosphoric acid hydroxyesters. The following reactions are possible: According to equation 1, phosphoric acid and its esters 1 react with the epoxide 2 to give a phosphoric acid hydroxyester derivative 3. Scheme 1 describes the addition of phosphoric acid and of its esters to epoxidised fatty acid glycerides. As the reaction scheme shows, in this process oligomeric triglycerides can also be formed by the phosphorylation reaction.
