摘要: This invention provides a novel azeotrope-like composition and a separation method using the composition. The invention provides an azeotrope-like composition comprising 1,2-difluoroethylene (HFO-1132) and hydrogen fluoride; an azeotrope-like composition comprising 1,1,2-trifluoroethylene (HFO-1123) and hydrogen fluoride; and a separation method of a composition comprising hydrogen fluoride and at least one member selected from the group consisting of trans-1,2-difluoroethylene (HFO-1132(E)), cis-1,2-difluoroethylene (HFO-1132(Z)), and 1,1,2-trifluoroethylene (HFO-1123).

摘要: Provided are a method for producing a fluoroethane, which is the desired product, with high selectivity; and a method for producing a fluoroolefin. The production method according to the present disclosure comprises obtaining a product comprising a fluoroethane represented by CX 1 X 2 FCX 3 X 4 X 5 (wherein X 1 , X 2 , X 3 , X 4 , and X 5 are the same or different and each represents a hydrogen atom, a fluorine atom, or a chlorine atom; and at least one of X 1 , X 2 , X 3 , X 4 , and X 5 represents a hydrogen atom) from a fluoroethylene by a reaction in the presence of at least one catalyst in at least one reactor. The reaction is performed by introducing a starting material gas comprising the fluoroethylene into the reactor, and the water content in the starting material gas is 150 ppm by mass or less based on the total mass of the starting material gas.

摘要: Disclosed is a method for improving the stability of a catalyst in recycling HFC-23. The recycling is realized by means of a fluorine-chlorine exchange reaction with HFC-23 and a halogenated hydrocarbon. The catalyst for the fluorine-chlorine exchange reaction comprises a main body catalyst and a metal oxide, wherein the metal oxide is selected from at least one metal oxide of K, Na, Fe, Co, Cu, Ni, Zn or Ti, and has an addition amount of 0.1-5wt%. The present invention has advantages such as a good catalyst stability, a long life, and a low content of by-product CFC-12.
