摘要
对甲醇气相直接氧化羰基化合成碳酸二甲酯反应的热力学以及反应中所使用的各种催化剂的制备、性能及催化机理进行了总结和分析。CuCl2／AC、Wacker型和CuI／分子筛催化剂是该反应使用的主要催化剂,其中CuI／分子筛催化剂可以在无氯存在下进行催化作用,避免了对设备的腐蚀,且活性和稳定性都比较好,有望成为该反应催化剂进一步研究的方向。
<abstract>Cl2/AC, Wacker and CuI /molecular sieve as important catalysts have been dramatically studied these years in gas-phase oxidative carbonylation of methanol to DMC. This is a thermodynamically favorable reaction. The preparation, catalytic properties and catalytic mechanism of these catalysts were reviewed and discussed.CuI/zeolite catalyst not only has a good stability and selectivity but can avoid erosion of reactors due to absence of chloride,and thus has a prosperous future.
