| titleOfInvention | Method for purifying tetrachloroethylene and process for producing hydrofluorocarbons |
| abstract | Tetrachloroethylene containing a stabilizer is contacted with a zeolite having an average pore size of 3.4 to 11 Å and/or a carbonaceous adsorbent having an average pore size of 3.4 to 11 Å in a liquid phase to obtain a high purity tetrachloroethylene. A halogenated alkene and/or a halogenated alkane are reacted with hydrogen fluoride in the presence of a fluorination catalyst to produce a first hydrofluorocarbon, a halogenated alkene and/or a halogenated alkane are reacted with hydrogen fluoride in the presence of a fluorination catalyst to produce a second hydrofluorocarbon, and these products are joined and then distilled to obtain the first and second hydrofluorocarbons. |
