| titleOfInvention | Process for removing contaminants from a hydrochlorofluoroolefin by extractive distillation. |
| abstract | A method of removing a contaminant from a hydrochlorofluoroolefin (such as trans-1,1,1-trifluoro-3-chloro-2-propene (1233zd (E))), using extractive distillation in the presence of an extracting solvent to form a purified hydrochlorofluoroolefin and chlorofluorocarbon This involves extracting chlorofluorocarbon (such as trichlorofluoromethane (R11)) from a mixture containing The separation method allows a contaminant such as R11 to be removed from a hydrochlorofluoroolefin such as 1232zd (E) that is not separated by conventional distillation methods. The method may use a process utilizing two distillation columns, a first leach distillation column and a second solvent recovery column, for example allowing the extractive solvent to be recycled into the first leach distillation column. |
