ABSTRACT:
Alkyl primary amines, e.g., tertiary alkyl primary amines, are prepared by reaction of the corresponding alkyl primary isocyanates with an alkanolamine to form an intermediate area reaction product, followed by heating to decompose the urea reaction product and form the amine product. The amine product can be recovered in high yield by vacuum distillation.
