Abstract:
A method of separating 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) and 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) includes providing an untreated composition including 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) and 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a). The untreated composition is treated with an adsorbent to form a treated composition in which the concentration of 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) is less than 93 percent of the concentration of the 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) in the untreated composition based on a treatment time of 24 hours.
