摘要
二氧化碳是一种低毒、不易燃、储量丰富且廉价易得的碳一资源,如何有效利用二氧化碳,将二氧化碳转化为高附加值化工品已成为当今研究热点。从能量利用及经济性角度考虑,将二氧化碳作为羧化试剂与具有高能量的起始原料反应,合成具有较高应用价值的羧酸(酯)或碳酸酯类衍生物是二氧化碳规模化利用的重要途径,目前受到了广泛关注。本文综述了近年来二氧化碳羧基化反应的研究进展,从反应的热力学、反应机理以及催化剂和反应工艺的改进等多个方面探讨了通过二氧化碳羧基化反应制备精细化工品的可行性及应用前景。并对该领域研究所存在的问题和局限性进行了总结。最后对今后的发展方向作了展望,指出二氧化碳化学工业的建立还需依赖基础研究的突破,需要开发高性能、廉价、适用范围广的过渡金属催化剂,实现二氧化碳的有效活化和利用。
Carbon dioxide is a kind of low toxic,non flammable,cheap and abundant C1 resource.The effective conversion of carbon dioxide to high value-added chemicals has become an attractive research topic.From the point of view of energy utilization and economy,the utilization of carbon dioxide as carboxylation reagent together with energetic materials to synthesize carboxylic acids or esters is an important way and has been attracted much attention.In this paper,the recent progress on the carboxylation of carbon dioxide is reviewed,and the feasibility and application prospect of the carboxylation route are discussed from the respect of reaction thermodynamics,mechanism and the improvements of catalyst and reaction process.And the problems and limitations of this research field are summarized.In the end,the future development direction is prospected.Establishment of CO2 chemical industry relies on the breakthrough of fundamental research.Highly active and cheap transition metal catalysts with wide application are urgently needed,in order to activate and utilize CO2.
