摘要
碳酸酯类化合物是21世纪最重要的绿色化学品,最典型的碳酸酯化合物碳酸二甲酯(DMC)是工业上广泛应用于溶剂、燃料添加剂以及化学试剂方向的重要化学品。由于DMC毒性很小,可以替代一些剧毒的化学品,如取代硫酸二甲酯和甲基卤化物用于甲基化反应。由于其高电介质常数、低黏度、低毒性以及优秀的溶解能力等性质,DMC被用作锂离子电池的电解液。微波技术能有效地提高催化剂活性组分的分散度,改善催化剂表面的晶体类型,提高催化剂的活性,在催化领域具有广阔的应用前景。介绍了微波技术应用于合成DMC反应中的催化剂制备,探究了微波技术对不同合成路径、不同催化剂合成DMC反应的影响,最后对微波技术对目前非均相催化剂合成DMC存在的问题以及今后的发展方向进行了总结与展望。
Carbonated compounds are the most important green products on 21st century, which are widely used in fields of biology green chemical industry and so on. Dimethyl carbonate(DMC), as a typical carbonate compound, is an important chemical in the industry and widely used in solvents, fuel additives, and chemical reagents. Due to low toxicity, DMC can replace some highly toxic chemicals, such as substituting sulfonic and methyl halide for methylation. Furthermore, its high dielectric constant, low viscosity, low toxicity and excellent solubility, DMC can be used as electrolyte for lithium ion batteries. Microwave technology can effectively improve the dispersion degree of the active component, improve the type of crystal on surface of the catalyst, and enhance the activity of the catalyst, and broad application prospect in the catalytic field. In this paper, the application of microwave technology in the preparation of catalysts for the synthesis of the DMC reaction introduces, and the effect of microwave technology on the synthesis of different synthetic pathways and different catalysts was explored. Finally, the development direction of microwave technology in the synthesis of the current non-normal catalyst for synthesis of DMC was prospected.
