Abstract:
A process for producing a composition comprising at least a quaternized ammonium compound having a substituted diethylamino moiety, comprising the steps of:(a) using a first organic compound from the group consisting of: (i) substituted and unsubstituted, saturated and unsaturated fatty acids having from about 6 to about 30 carbon atoms; (ii) substituted and unsubstituted, saturated and unsaturated fatty acids having from about 6 to about 30 carbon atoms, wherein said fatty acid at least contains one or more atoms selected from the group consisting of oxygen, sulfur and phosphorous; and (iii) combinations thereof; (b) using an alkyl polyamine from the group having the general formula: H2Nâ€”CH2â€”(CH2)pâ€”NHâ€”(CH2)qâ€”NH2 wherein p=1 to about 5 and q=2 to about 10; (c) using a second organic compound from the group consisting of: (i) substituted and unsubstituted, &agr;,&bgr;-unsaturated carboxylic fatty acids, and amide and ester derivatives thereof, having from about 3 to about 11 carbon atoms; (ii) substituted and unsubstituted, &agr;,&bgr;-unsaturated sulfonic and phosphonic fatty acids having from about 2 to about 11 carbon atoms; and (iii) combinations thereof; (d) reacting said first organic compound and said alkyl polyamine in a mole ratio in a range of from about 0.6:1 to about 1.2:1 to produce at least one intermediate compound, wherein said mole ratio is the total moles of said first organic compound to the total moles of said alkyl polyamine; and (e) reacting said at least one intermediate compound with said second organic compound to produce said composition.
