In recent years, the chemical industry has put emphasis on designing or modifying chemical processes that would increasingly meet the requirements of the adopted proecological sustainable development strategy and the principles of green chemistry. The development of cyclic carbonate synthesis from CO and epoxides undoubtedly follows this trend. First, it represents a significant improvement over the older glycol phosgenation method. Second, it uses renewable and naturally abundant carbon dioxide as a raw material. Third, the process is most often solvent-free. However, due to the low reactivity of carbon dioxide, the process of synthesising cyclic carbonates requires the use of a catalyst. The efforts of researchers are mainly focused on the search for new, effective catalysts that will enable this reaction to be carried out under mild conditions with high efficiency and selectivity. Recently, deep eutectic solvents (DES) have become the subject of interest as potential effective, cheap, and biodegradable catalysts for this process. The work presents an up-to-date overview of the method of cyclic carbonate synthesis from CO and epoxides with the use of DES as catalysts.
近年来，化学工业一直致力于设计或改进化学工艺，使其越来越符合所采用的生态友好可持续发展战略和绿色化学原则的要求。从 CO 和环氧化物合成环状碳酸酯无疑符合这一趋势。首先，它显著优于旧的甘醇光气化法。其次，它使用可再生和天然丰富的二氧化碳作为原料。第三，该工艺大多是无溶剂的。然而，由于二氧化碳的低反应性，合成环状碳酸酯的过程需要使用催化剂。研究人员的努力主要集中在寻找新的、有效的催化剂，以使该反应能够在温和条件下以高效率和选择性进行。最近，深共熔溶剂（DES）作为该过程的潜在有效、廉价和可生物降解的催化剂，引起了人们的兴趣。本文综述了以 DES 为催化剂从 CO 和环氧化物合成环状碳酸酯的最新方法。
