Optimization of 1,2-Diaminopropane Preparation by the Ammonolysis of Waste 1,2-Dichloropropane

The studies of ammonolysis process of waste 1,2-dichloropropane using liquid ammonia in the presence of CuO as a catalyst have been performed. The technological parameters allowing the highest yield of 1,2-diaminopropane at the complete conversion of 1,2dichloropropane have been established. The statistical methods of the design of experiments were utilized. The influence of the molar ratio of ammonia to 1,2-dichloropropane on temperature and reaction time and of the catalyst concentration on the course of the process was examined. The results were presented in the form of polynomials of the second order (regression equations) describing the influence of mentioned factors (technological parameters) on the conversion of NH3 and 1,2-dichloropropane and the selectivity of transformation to 1,2-diaminopropane in relation to consumed 1,2-dichloropropane.
