First Claim
1. A PROCESS FOR IMPARTING TO A CELLULOSIC TEXTILE SELF-EXTINGUISHING CHARACTER, THE PROCESS COMPRISING A. IMPREGNATING A CELLULOSIC TEXTILE WITH AN AQUEOUS SOLUTION CONTAINIING ABOUT 30% OF TETRAKIS(HYDROXYMETHYL)PHOSPHONIUM CHLORIDE, B. DRYING THE WET IMPREGNATED CELLULOSIC TEXTILE FOR ABOUT 4 MINUTES, AT ABOUT 85.C, C. REACTING THE TEXTILE OF (B) UPON IMPREGNATION WITH AN ETHANOLIC SOLUTION CONTAINING ABOUT 60% ANILINE, AND D. ALLOWING THE REACTION TO COME TO COMPLETION UPON AIRDRYING THE REIMPREGNATED CELLULOSIC TEXTILE.

Abstract
Novel quaternary arylaminoalkyl phosphonium salts having the formula ((ArNHCHR)4P) 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)4P) 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.
