| titleOfInvention | PROCEDURE FOR THE ELIMINATION OF POLLUTANTS FROM A HYDROCLOROFLUORO-OLEFINA BY EXTRACTIVE DISTILLATION. |
| abstract | One method of separating a contaminant from a hydrochlorofluoro-olefin (such as trans-1,1,1-trifluoro-3-chloro-2-propene (1233zd (E))) includes extracting a chlorofluorocarbon (such as trichlorofluoromethane (R11)) of a mixture comprising hydrochlorofluoro-olefin and chlorofluorocarbon using an extractive distillation in the presence of an extractive solvent comprising a gold compound, to form a purified hydrochlorofluoro-olefin. This separation method provides for the removal of a contaminant such as R11 from a hydrochlorofluoro-olefin such as 1232zd (E), which are not separable by conventional distillation methods. The method may employ a method that uses two distillation columns, for example a first extractive distillation column and a second solvent recovery column, which allows recycling of the extractive solvent to the first extractive distillation column. |
