METHOD FOR PRODUCING 1,2-DICHLORO-3,3,3-TRIFLUOROPROPENE |
| 摘要 |
The present invention has an object of providing a method for producing 1,2-dichloro-3,3,3-trifluoropropene by a vapor-phase reaction easily and in an industrial scale. A method for producing 1,2-dichloro-3,3,3-trifluoropropene of the present invention includes putting 1,2-dichloro-1-halogeno-3,3,3-trifluoropropane with an activated carbon catalyst in a vapor phase. According to the present invention, 1,2-dichloro-3,3,3-trifluoropropene is produced in an industrial scale at a high yield by use of 1,2-dichloro-1-halogeno-3,3,3-trifluoropropane, which is available at low cost, as a material. |
