ABSTRACT:
Phosphinated or phosphonated sulfonic acid compounds are prepared by a process comprising reacting a hypophosphite salt, such as an alkali metal hypophosphite, with an alkenyl sulfonic acid compound of the formula CH.sub.2 .dbd.C(R)C(O)NH--Z--SO.sub.3 --M.sup.+, wherein Z is a divalent (C.sub.1 -C.sub.18)hydrocarbyl group, R is H or (C.sub.1 -C.sub.7)alkyl and M.sup.+ is H.sup.+, NR.sub.4.sup.+ or an equivalent metal cation, such as an alkali metal cation.
