摘要
对甲醇液相氧化羰基化法合成碳酸二甲酯过程的反应焓变、反应熵变、吉布斯自由能变、平衡常数及平衡转化率进行了热力学估算。结果表明:此反应为一放热反应,反应条件下向正方向自发进行的趋势明显,热力学平衡常数很大,甲醇平衡转化率比较大,预示催化甲醇液相氧化羰基化反应具有进一步开发的潜力。
The reaction heat, reaction entropy, Gibbs free energy, equilibrium constant and conversion of methanol for the synthesis process of dimethyl carbonate by liquid oxidation carbonylation of methanol were calculated. The results showed that the liquid oxidation carbonylation is exothermic and spontaneous under the reaction conditions. Equilibrium constant and conversion of methanol are very high, which indicates that the catalytic reaction of liquid oxidation carbonylation of methanol has good potential for further development.
