摘要： The present invention provides a process for purifying a (E)-1-chloro-3,3,3-trifluoropropene composition (OF-1233E composition) in which at hydrogen fluoride and 2-chloro-1,1,1,3,3-pentafluoropropane are contained by bringing the(E)-1-chloro-3,3,3-trifluoropropene composition into contact with a weak base and a method for producing (E)-1-chloro-3,3,3-trifluoropropene composition by distilling the (E)-1-chloro-3,3,3-trifluoropropene composition obtained by such a purification process. This makes it possible to efficiently produce OF-1233E by removing the hydrogen fluoride from the OF-1233E composition, without generating any new component difficult to separate by distillation, and subjecting the resulting composition to distillation.

摘要： Disclosed is a process for producing 2-chloro-1,3,3,3-tetrafluoropropene (1224), including a first step of separating 2,3-dichloro-1,1,1,3-tetrafluoropropane (234da) into erythro form and threo form, and a second step of bringing the separated erythro form or threo form in contact with a base to obtain 2-chloro-1,3,3,3-tetrafluoropropene (1224). The first step is a step of separating 234da by distillation to achieve a separation into a fraction containing mainly erythro form and a fraction containing mainly threo form. In the second step, 1224 cis form is obtained from the erythro form, and 1224 trans form is obtained from the threo form. By this process, it is possible to selectively and efficiently produce cis form or trans form of 2-chloro-1,3,3,3-tetrafluoropropene (1224).
