摘要：Novel acyl-containing amine hydrochlorides are produced by first convertingthe amino group or groups of an amino acid to an acid salt by reaction with hydrochloricacid and the resulting product is reacted with an alkanolamine or diol in an inert liquidmedium while passing a stream of hydrogen chloride gas therethrough. The aminehydrochlorides produced in this manner may be converted to the correspondingisocyanates by reaction with phosgene or other carbonyl dihalide.
