Abstract: A process is disclosed for making CF3CF═CHF. The process involves reacting CF3CClFCCl2F with H2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF3CF═CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H2 to CF3CClFCCl2F fed to the reaction zone is between about 1:1 and about 5:1. Also disclosed are azeotropic compositions of CF3CClFCCl2F and HF and azeotropic composition of CF3CHFCH2F and HF.

Abstract: Disclosed are can taps for dispensing fluids from containers. The can tap has a housing with an inlet and an outlet, and a pin. The pin has a flow portion in fluidic communication with the inlet and the outlet of the housing. The pin may have a blunt depressor capable of operating a valve on the container. The flow portion of the pin allows fluid to flow between the housing and the pin. The can tap may have a gasket comprising a material having a hardness that prevents deformation of the container.
