Propane-1,3-diol phosphatides and method of preparing the same

摘要

Propane-1,3-diol phosphatides of the formula are prepared from the corresponding 1-alkanoyl-propanediols by conversion to an intermediate alkanoyl-propanediol-phosphoric acid beta -bromoethyl ester with beta -bromoethylphosphoric acid dichloride, and amination of the intermediate. They are biodegradable surfactants useful in detergent compositions and as emulsifiers in foods. In the formula, n is an integer and 9 to 25, R1 and R2 may be hydrogen or alkyl having up to six carbon atoms, and R3, R4, R5 may be hydrogen or methyl, but at least one of R3, R4, and R5 is hydrogen when R1 and R2 are both hydrogen.
