Abstract

α, ω-Type amphoteric surfactants containing bisbetaine groups were synthesized by reactions of alkanedioic acids with N, N-dimethyl-1, 3-propanediamine, followed by quaternization of the resulting bisaminoamides with sodium chloroacetate. The latter process was carried out in water or a mixture of isopropyl alcohol and water using sodium hydrogencarbonate or sodium hydroxide as the catalyst.<BR>The properties of the α, ω-bisamidobetaine in aqueous solution were studied. α, ω-Bisamidobetaines derived from hexadecanedioic and icosanedioic acid showed good catalytic activity for the halide displacement reaction and a excellent ability to bring about lime soap dispersion.
