摘要： The present invention provides a method for purifying chlorinated hydrocarbon(s), comprising cooling a mixture containing hydrogen fluoride and at least one chlorinated hydrocarbon selected from the group consisting of 2-chloro-3,3,3-trifluoropropene, 2,3-dichloro-3,3-difluoropropene, 1,2,3-trichloro-1,1-difluoropropane, and 1,1,1,2,3-pentachloropropane to cause liquid-liquid separation of the mixture into an upper liquid phase having a high hydrogen fluoride concentration and a lower liquid phase having a high chlorinated hydrocarbon concentration, and a method for purifying a chlorinated hydrocarbon, comprising subjecting the lower liquid phase obtained by the liquid-liquid separation to a distillation operation. According to the present invention, a chlorinated hydrocarbon can be purified by separating and removing hydrogen fluoride from a chlorinated hydrocarbon-hydrogen fluoride mixture under simple and economically advantageous conditions.

摘要： The present invention provides a method for purifying HFO-1234yf, comprising the steps of (1) cooling a liquid mixture containing HFO-1234yf and HF to separate the mixture into a upper liquid phase having a high concentration of HF and a lower liquid phase having a high concentration of 2,3,3,3-tetrafluoropropene; and (2) subjecting the lower liquid phase obtained in step (1) to a distillation operation to withdraw a mixture containing HFO-1234yf and HF from a top of a distillation column, thereby obtaining substantially HF-free HFO-1234yf from a bottom of the distillation column. According to the present invention, HF and HFO-1234yf contained in a mixture containing HF and HFO-1234yf can be separated under simple and economically advantageous conditions.
摘要翻译：本发明提供了一种净化HFO-1234yf的方法，包括以下步骤：（1）冷却含有HFO-1234yf和HF的液体混合物，以将混合物分离成具有高浓度HF和较低液相的上液相，高浓度的2,3,3,3-四氟丙烯; 和（2）将在步骤（1）中获得的下部液相进行蒸馏操作从蒸馏塔的顶部排出含有HFO-1234yf和HF的混合物，从而从底部获得基本上无HF的HFO-1234yf 蒸馏塔。根据本发明，包含在含有HF和HFO-1234yf的混合物中的HF和HFO-1234yf可以在简单且经济上有利的条件下分离。
