Propane-1,3-diol phosphatides of the formula ##STR1## are prepared from the corresponding 1-alkanoyl-propanediols by conversion o 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, R.sub.1 and R.sub.2 may be hydrogen or alkyl having up to six carbon atoms, and R.sub.3, R.sub.4, R.sub.5 may be hydrogen or methyl, but at least one of R.sub.3, R.sub.4, and R.sub.5 is hydrogen when R.sub.1 and R.sub.2 are both hydrogen.
公式为## STR1##的丙烷-1,3-二醇磷脂是通过将相应的1-烷酰基丙二醇转化为中间体烷酰基丙二醇磷酸.beta.-溴乙酯,然后通过.beta.-溴乙基磷酸二氯酯的胺化反应制备而成。它们是可生物降解的表面活性剂,在洗涤剂配方中和作为食品乳化剂中有用。在该公式中,n为整数,范围为9至25,R.sub.1和R.sub.2可以是氢或具有最多六个碳原子的烷基,R.sub.3、R.sub.4和R.sub.5可以是氢或甲基,但当R.sub.1和R.sub.2都是氢时,至少有一个R.sub.3、R.sub.4或R.sub.5是氢。
