-

, (2008/06/13)

Novel quaternary arylaminoalkyl phosphonium salts having the formula [(ArNHCHR)4 P]+X-, 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)4 P]+X-, 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.
