Propane-1,3-diol phosphatides of the formula ##STR1## are prepared from the corresponding 1-alkanoyl-propanediols by conversiono an intermediate alkanoyl-propanediol-phosphoric acid β-bromoethyl ester with β-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, R 1 and R 2 may be hydrogen or alkyl having up to six carbon atoms, and R 3 , R 4 , R 5 may be hydrogen or methyl, but at least one of R 3 , R 4 , and R 5 is hydrogen when R 1 and R 2 are both hydrogen. |
