Thermodynamics of the synthesis of dibutyl toluene-2,4-dicarbamate
摘要
Abstract
The standard enthalpy of formation, free energy and heat capacity of the components in the synthesis of dibutyl toluene-2,4-dicarbamate from 2,4-diamino toluene, urea and butyl alcohol were calculated by methods of group contribution. The enthalpy change, Gibbs free energy and equilibrium constant of the reactions were calculated and discussed at the temperature range of 300-500K. The results indicated that the synthesis of dibutyl toluene-2,4-dicarbamate is thermodynamically feasible, and the obtained results provides theoretical basis for further experimental research and development of the reaction process.关键词
