ABSTRACT:
Novel acyl-containing amine hydrochlorides are produced by first converting the amino group or groups of an amino acid to an acid salt by reaction with hydrochloric acid and the resulting product is reacted with an alkanolamine or diol in an inert liquid medium while passing a stream of hydrogen chloride gas therethrough. The amine hydrochlorides produced in this manner may be converted to the corresponding isocyanates by reaction with phosgene or other carbonyl dihalide.
