Abstract:
A composition of matter consisting essentially of the product(s) obtained by reacting:(i) a diethanolamine; (ii) an amine-group containing compound selected from the group consisting of N-methyl piperazine, 3,3â€²-iminobis (N,N-dimethyl propylamine), and N,N-dimethylethanolamine; and (iii) a hydrocarbyl-substituted succinic acylating agent, wherein the amine-group containing compound (ii) comprises at least one member selected from the group consisting of a) polyamines containing at least one secondary amine group and optionally at least one tertiary amine group, b) tertiary amino alcohols containing at least one hydroxy group and at least one tertiary amine, c) alkylene polyamines of the formula H2Nâ€”(Aâ€”NHâ€”)nH, where A is divalent ethylene or propylene and n is an integer of from 1 to 10 and d) polyamines having at least one primary amino group and at least one tertiary amino group; and wherein said product(s) are formed by reacting a hydrocarbyl-substituted succinic acylating agent (iii), a hydroxyl-group containing compound (i); and an amine-group containing compound (ii) in the molar ratios of 1.0:0.2-1.8:0.2-1.8, respectively.
