Approximately 360 g of N-oleyl-1,3-propylenediamine (commercially obtained as Armak Duomeen O) and 150 g of toluene were charged to a 2 liter reactor equipped as described in Example 1. Approximately 52 g of 88% formic acid were slowly added and the reaction mixture was heated to about 160° C. over a period of about 5 hours until water removed by azeotropic distillation ceased. The solvent was removed by vacuum distillation at 160° C. and the mixture was cooled to about 60° C.
