Reaction Steps

To a 5 liter stirred reactor, equipped with a distillation column, condenser, and graduated receiver, the following constituents were added: 1250.0 g of diisopropanol amine (DIPA) and 1502.5 g (98%) of lauric acid. The contents were heated to 186° C. under a nitrogen blanket over a 90 minute period. During that time, 136 ml of water came overhead. The batch temperature was held at 184° C. while the pressure was dropped to 320 Pa. During the pressure reduction, 410 g of unreacted DIPA came overhead. A total of 1192 g of amide acetal derived from lauric acid was collected while the temperature was raised to 220° C. at a pressure of 280-466 Pa. This represents a 53.5% conversion of the lauric acid.
