摘　　要：研究了以二氧化硅负载聚丙烯腈-丙烯酰胺-金属(PAN-AM-M)配合物为催化剂,在环氧氯丙烷存在下,由甲醇和二氧化碳直接合成碳酸二甲酯的反应活性。考察了反应条件的影响。结果表明,PAN-AM-Zn表现出较高活性,合成碳酸二甲酯的最佳反应条件为:甲醇与环氧氯丙烷的原料配比为4∶1,反应温度130℃,催化剂用量2%(反应物料质量百分数)。In this work, dimethyl carbonate was synthesized with carbon dioxide and methanol by the catalysis of metal complex polymer in the presence of epichlorohydrin. The synthetic conditions were also discussed. Results showed that PAN-AM-Zn metal complex polymers had the highest catalytic activity among 5 kinds of metal complexes. The optimum reaction conditions on PAN-AM-Zn are: reaction temperature 130℃, catalyst concentration 2%,(By wt.) molar ratio (methanol/epichlorohydrin) 4∶1.
