Investigation on the Optimization of the Synthesis Processes of Morpholine from Residual Liquid of Morpholine Industry

Aimed to reduce the impact on the environment about waste liquor of morpholine industry,and to increase the profit of it, in this paper, morpholine synthesis from industrial morpholine residual is discussed and optimized, by the method of pressurized hydrolysis reaction. The kinds and volume of catalyst and system temperature-pressure and other reaction conditions are analyzed and optimized to obtain the best yield rate of morpholine. Experiments suggest that pressurized hydrolysis reaction, using sodium hydroxide as catalyst, could be an efficient method to synthesize morpholine from industrial morpholine residual.
