摘　　要：综述了由甲醇、一氧化碳、二氧化碳、环氧丙烷、尿素等出发,采用非光气工艺路线依次合成碳酸二甲酯、碳酸二苯酯及高质量聚碳酸酯(PC)的清洁生产工艺。重点对非光气法合成的各种生产工艺与传统的光气法进行比较,指出非光气法PC生产工艺路线已显示出明显优势,具有无污染、原子利用率高、产品品质好等优点。The clean processes for the production of dimethyl carbonate, diphenyl carbonate and the high qualifity polycarbonates by adopting the non- phosgene route, with the basic chemical methanol, carbon monoxide, carbon dioxide, propylene oxide,urea, etc. as raw materials, are reviewed, with the emphasis put on the comparasions of various non-phosgene progress with the traditional phosgene one. It is pointed out that the non-phosgene methods for producing polycarbonate have already had the advantages gradually, such as no pollution, high utilization of atom, excellent product quality.
