Reaction Conditions

Reaction Steps

In a 500 ml SUS 316L stainless steel autoclave were charged 60 g of ethylene diamine, 267 g of stearonitrile and 2.5 g of titanium tetraisopropoxide. After addition of 1 g of water, the mixture was heated up to 210° C. with stirring and maintained at that temperature for 4 hours while removing ammonia produced in situ to maintain the pressure within the autoclave at 8-9 kg/cm2G. The resulting mixture was then subjected to vacuum distillation at 0.6 mmHg and at 230°-235° C. to obtain 267 g of 2-heptadecyl-2-imidazoline with a yield of 86%.
