Abstract

The invention relates to new quaternary ammonium salts of di and trisulfonated triarylphosphines as well as a process for their preparation. The salts are of Formula I ##STR1## wherein Ar.sub.1, Ar.sub.2, and Ar.sub.3 are each independently an aryl; X.sup.1, X.sup.2, and X.sup.3 are each independently a sulfogroup; y.sup.1, y.sup.2, and y.sup.3 are each independently 0 or 1, provided that their sum is at least 1; A is an alkyl, hydroxyalkyl, aralkyl, or aryl having 6-25 carbon atoms; B, C, and D are straight chain or branched alkyl having 1-4 carbons; and n is a whole number of 1-3.
