DESCRIPTION

Ammonium Salts of Phosphatidic Acid occurs as a brownish, unctuous semisolid to oily liquid. It is soluble in fats, partially soluble in ethanol and acetone, and insoluble in water. The product consists principally of a mixture of the ammonium compounds of phosphatidic acids derived from edible fats and oils. One or two mono- and diglyceride moieties may be attached to phosphorus. Moreover, two phosphorus esters may be linked together as phosphatidyl phosphatides. The product is obtained by glycerolysis of the fat, followed by phosphorylation with phosphorus pentoxide, and neutralization with ammonia. The article of commerce may be further specified as to water content, hexane-insoluble matter, and pH value.
