Abstract
PURPOSE: To obtain the title compound useful as a raw material for pesticides or coating materials advantageously, by controlling the ammonia concentration in the circulating gas with water in such a state as to correspond to the gas temperature introduced into the reaction or condensation system reading and economically without adversely affecting the other steps.
CONSTITUTION: Water in such a state as to correspond to the gas temperature is introduced into the reaction system, wherein an aliphatic nitrile is catalytically reduced in the vapor phase or a primary amine is converted into a secondary one in the presence of a circulating gas comprising hydrogen and ammonia, or the condensation system, wherein the reaction gas thus obtained is separated into a condensate containing an alkylamine and a noncondensible gas, the circulating gas being circulated through the reaction system. The exess ammonia formed in the reaction is separated in the condensate together with water.
EFFECT: Ammonia concentration in the circulating gas cab be controlled independently of the methane concentration without using special ammonia removal units.
