    摘要： A production method of difluoroacetyl chloride according to the present invention includes a chlorination step of bringing a raw material containing at least either a 1-alkoxy-1,1,2,2-tetrafluoroethane or difluoroacetyl chloride into contact with calcium chloride at a reaction enabling temperature. A production method of 2,2-difluoroethyl alcohol according to the present invention includes a catalytic reduction step of causing catalytic reduction of the difluoroacetyl chloride obtained by the above production method. By these methods, the difluoroacetyl fluoride can be efficiently converted to the difluoroacetyl chloride and to the 2,2-difluoroethyl alcohol.

    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.
