82 g of β-hydroxypropionamide and 195 g of dodecylamine were heated with 50 mg of 2,6-di-t-butyl-p-cresol for 4 hours in a temperature range of 130° C. to 190° C. unitl the evolution of ammonia was complete. After adding 5 g of polyphosphoric acid the reaction mixture was maintained at 160° C. for 1 hour and then distilled in an oil pump vacuum. The main run was taken off between 148° C. and 168° C. at 0.3 bar and crystallized in the receiver.
