中文摘要：
碳酸二甲酯（DMC）是一种重要的绿色有机合成中间体。在合成DMC的方法中,甲醇氧化羰基化法对设备腐蚀小、原料易得、产物易分离,有着诱人的工业化前景。文中介绍了该反应中所使用的Co、Pd、Cu和Au这4类催化剂的结构特点和催化性能,比较了不同催化剂在氧化羰基化中的催化效果。为了进一步提高催化剂的活性、选择性、减少其腐蚀性,开发出性能更好的工业催化剂,可以通过研究催化反应机理,并通过添加助剂和载体来实现。其中无卤铜系催化剂是今后羰基化合成DMC的重要研究方向。
英文摘要：
There are several methods for the synthesis of dimethyl carbonate,especially,the oxidative carbonylation of methanol has an attractive industrial prospects due to its features of low erosion,relatively easier separation of products,attainable raw materials,etc.The structural features and catalytic performances of Co,Pd,Cu and Au systems were introduced and compared in the oxidative carbonylation of methanol to dimethyl carbonate.In order to promote the catalytic performance and selectivity of the catalyst,extending its life and reducing its corrosion,the reaction mechanism should be further studied,and the effective catalyst promoters and catalyst carriers should be added.The halogen-free copper catalysts are the important research direction for the carbonylation synthesis of dimethyl carbonate.
