  • 1,2-O-dialkylmethylidene-glycero-3-phosphatides
    Patent number: 3940423
    Abstract: Glycerol is reacted with a ketone having 19 to 35 carbon atoms to 1,2-O-dialkylmethylidene-glycerol which is phosphorylated by means of .beta.-bromoethylphosphoric acid dichloride. The resulting intermediate is aminated with ammonia, methylamine, dimethylamine, or trimethylamine to a compound of the formula ##EQU1## wherein R.sub.1 and R.sub.2 are alkyl having 9 to 17 carbon atoms, and R.sub.3, R.sub.4, and R.sub.5 are hydrogen or methyl. The compounds and their non-toxic acid addition salts are surfactants which may be employed in detergent compositions or as emulsifiers in food.
