FDN-641/688/B AMPHOTERIC SURFACE ACTIVE AGENTS ABSTRACT Complex phosphate ester surfactants derived from a quaternary dihydroxy compound having the formula: Image X- wherein R and R1 represent the same or different alkyl moieties containing 1 to 22 carbon atoms, the sum of R and R1 not being less than 7 carbon atoms; R2 and R3 each represent H or CH3; n is an integer having an average value of from 1 to 50; X is an anion of halogen, sulfate, or alkyl sulfate; and wherein the resultant complex phosphate ester contains at least 1/3 P atom per mole of quaternary dihydroxy compound; can be made through reaction of such dihydroxy quaternary compound with a conventional phos- phating agent such as P2O5, polyphosphoric acid, or POC13 to form interesting amphoteric surface active agents having utility as metal lubricants, heavy duty cleaners, and detergents.
