| titleOfInvention | Method for preparing 1,1,1,3,3,3-hexafluoroacetone through gas-phase catalysis |
| abstract | The invention provides a method for preparing 1,1,1,3,3,3-hexafluoroacetone through gas-phase catalysis, relating to the field of organic synthesis. The method comprises the following reaction steps: (1) introducing 1,1,3,3-tetrafluoro-1,3-dichloroacetone gas and hydrogen fluoride gas into a fixed bed type reactor with a supported catalyst, and reacting; and (2) rectifying the gas discharged from the fixed bed type reactor to obtain the 1,1,1,3,3,3-hexafluoroacetone. According to the method for preparing 1,1,1,3,3,3-hexafluoroacetone through gas-phase catalysis, the tetrafluorodichloroacetone is used as the raw material; and the process is simple and environment-friendly, low in cost and high in yield. |
