摘要
Abstract
The basic data and thermodynamic data of dimethyl carbonate ( DMC ) and phenyl carbamate ( MPC ) were calculated by ABW, Fedors' groups addition and three groups addition, obtaining a detailed thermodynamic analysis of the synthesizing MPC with DMC and aniline. It is an important guiding significance for the entire process and enriches the basic data of raw materials in polyurethane industry. The relationship between reactive temperature and reactive enthalpy, Gibbs free energy, as well as the equilibrium constant, was established. The results show that the reaction is a spontaneously exothermic reaction. The lower the temperature is, the easier the reaction advances to MPC, and the reaction could carry out spontaneously at a low temperature. However, the reaction takes longer time because of the slow reactive rate and more side effects lead to the decreasing of products yields if the reaction is in progress at a temperature that is not high enough. Therefore, in practical application the reaction takes place by adding catalysts at about 150℃.关键词
