| 主权项 | 1. A process for removing one or more undesired (hydro)halocarbon compounds from a hydrofluoroalkene, the process comprising contacting a composition comprising the hydrofluoroalkene and one or more undesired (hydro)halocarbon compounds with activated carbon, wherein the hydrofluoroalkene is free of a ═CF2 moiety wherein at least one (hydro)halocarbon is selected from the group consisting of (hydro)fluoroalkanes, (hydro)fluoroalkenes, (hydro)fluoroalkynes and (hydro)chlorofluorocarbon (CFC) species. | ||
