| titleOfInvention | Process for removing a contaminant from a hydrochlorofluoroolefin by extractive distillation |
| abstract | A distillation process comprising: feeding a feed mixture comprising a hydrochlorofluoroolefin comprising a contaminant to a first distillation column; and extracting the contaminant from the feed mixture in the first distillation column using an extraction solvent comprising a chlorinated compound selected from the group consisting of trichloroethylene, carbon tetrachloride, chloroform, 1,1,1-trichloroethane, and mixtures thereof. same to form an overhead stream comprising a purified hydrochlorofluoroolefin and a bottom stream comprising the contaminant and extraction solvent; wherein the contaminant comprises trichlorofluoromethane (R11). |
