CO2的化学固定是解决将来大气中CO2含量增加的重要手段。该文对近期CO2化学固定的研发工作进行了综述,包括合成环状碳酸酯、碳酸二甲酯(DMC)、环状尿素和环状尿烷。CO2加入到环氧化物中合成环状碳酸酯已经工业化,但催化剂的研制工作仍在继续。采用烯烃直接氧化羧基化合成环状碳 Chemical fixation of CO2 is an important means to solve the problem of increasing CO2 content in the atmosphere in the future. In this paper, recent developments of CO2 chemical immobilization were reviewed, including synthesis of cyclic carbonates, dimethyl carbonate (DMC), cyclic ureas and cyclic urethanes. The synthesis of cyclic carbonates by the addition of CO2 to epoxides has been industrialized, but the development of catalysts continues. The use of olefins direct oxidation of carboxyl synthesis of cyclic carbon
