Abstract

In this work the synthesis of monoamines  on the base of  acetylene amino- alcohols and diamines in the presence of acetylene, paraform and secondary ami-nes by the Mannich reaction.was inivestigated. The structure, physico-chemical culconstants and conditions of formation of synthesized monoamines and diamines with high yields have been determined. In the molecules of monoamines and diamines there are chemically active centers: -C ≡ C-, atom –N= and -C ≡ C - H. The reactions  halogenation of triple bond by halogenated acids and the formation of a quaternary salts  have been studied. The structure of the synthesized products was confirmed by IR and PMR spectrums. Their physico-chemical constants and yields have been determined. Dependence of the products yield on the nature of the used catalysts was  determined.
