催化合成氟代碳酸乙烯酯的研究

The Research on Synthesis of Fluoroethylene Carbonate under Catalyzing

以氯代碳酸乙烯酯为原料,在催化剂β-环糊精的作用下,以氟化钾作为氟化试剂,通过卤素交换反应制备氟代碳酸乙烯酯。分别考察了催化剂的效果,以及反应温度,反应时间对反应产率的影响。经过优化反应条件,使产率达到94.3%。并利用核磁共振氢谱、质谱对产物进行表征。

The new compound fluoroethylene carbonate was synthesized with chloroethylene carbonate and potassium fluoride under the phase transfer catalyst β- cyclodextrin. The influences factors on yield by the catalyst, the temperature and the react time were discussed. The yield reaches were up to 94. 3% after improve the reaction conditions. The product was characterized by 1H NMR and ESI- MS.
