摘要
Abstract
The basic data and thermodynamic data of iV-methyl diethanolamine (MDEA) were calculated by ABW, Fedors' groups addition, obtaining a detailed thermodynamic analysis of synthesizing MDEA with EO and armour amine. It provides the conditions required for the synthesis process in theory. The relationship of reactive temperature with reactive enthalpy, Gibbs free energy, as well as the equilibrium constant was established. The results show that it is an exothermic spontaneously reaction. The lower the temperature is, the easier the reaction is advancing toward synthesis of MDEA. However,the reaction takes longer time because of the slow reactive rate,thus leading to the decrease of products yields if the reaction temperature is not high enough. Therefore,in the industrial production, the reaction is taken place at about 100-150℃ and the pressure in the reactor is generally 3-6 MPa.关键词
