摘要： A process for the preparation of purified fluorosubstituted organic carbonates, especially of fluoroethylene carbonate, difluoroethylene carbonate, fluoromethyl methyl carbonate and difluorinated dimethyl carbonate from ethylene carbonate and dimethyl carbonate and F 2 is described. After fluorination, and preferably after performing a step of hydrogen fluoride depletion, the impure fluorosubstituted organic carbonates are subjected to a treatment with an agent of formula (I), R-H, wherein R is a nucleophilic group, and a subsequent step of distillation in at least one distillation column. Alcohols and amines, for example, are suitable as agent of formula (I). Methanol is especially preferred.
摘要翻译：描述了从碳酸亚乙酯和碳酸二甲酯和F2制备纯化的氟取代的有机碳酸酯，特别是氟代亚乙基碳酸酯，二氟亚乙基碳酸酯，氟甲基甲基碳酸酯和二氟化碳酸二甲酯的方法。在氟化后，优选在进行氟化氢消耗的步骤之后，将不纯的氟代取代的有机碳酸酯用式（I），RH（其中R是亲核基团）的试剂进行处理，随后在至少一个蒸馏塔。醇和胺例如适合作为式（I）的试剂。甲醇是特别优选的。
