Abstract
Novel quaternary arylaminoalkyl phosphonium salts having the formula [(ArNHCHR).sub.4 P].sup.+X.sup.-, where R is a radical selected from the group consisting of hydrogen, alkyl and aryl, Ar is aryl, and X is halogen, are prepared by the reaction of primary aromatic amines with quaternary hydroxyalkyl phosphonium salts having the formula [(HOCHR).sub.4 P].sup.+X.sup.-, where R and X are similarly defined. The compounds of this invention are useful as flame retardant for cotton, plasticizers, lubricant additives, and surface-active agents.
