Method for Producing (E)-1-Chloro-3,3,3-Trifluoropropene |
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. |

1. A production process of (E)-1-chloro-3,3,3-trifluoropropene, comprising:
providing a (E)-1-chloro-3,3,3-trifluoropropene composition, the (E)-1-chloro-3,3,3-trifluoropropene composition containing at least hydrogen fluoride and 2-chloro-1,1,1,3,3-pentafluoropropane; and bringing the (E)-1-chloro-3,3,3-trifluoropropene composition into contact with a weak base. |
