| titleOfInvention | Process for the removal of contaminant from a hydrochlorofluoroolefin by extractive distillation |
| abstract | A method for removing a contaminant from a hydrochlorofhioroolefin (such as trans- 1,1,1-trifluoro-3-chloro-2-propene (1233zd(E))) includes extracting a chlorofluorocarbon (such as trichlorofluoromethane (R11)) from a mixture comprising the hydrochlorofhioroolefin and the chlorofluorocarbon using extractive distillation in the presence of an extractive solvent comprising a chlorinated compound to form a purified hydrochlorofhioroolefin. This separation method provides for removal of a contaminant, such as R11, from a hydrochlorofhioroolefin, such as 1232zd(E), which are not separable by conventional distillation methods. The method may employ a process utilizing two distillation columns, for example, a first extractive distillation column and a second solvent recovery column, which allows for recycle of the extractive solvent to the first extractive distillation column. |
