Antimony pentafluoride

 Antimony pentafluoride (SbF₅) is used mainly as a catalyst, especially in the production of perfluroalkyliodides(PFAIS). PFAIS is a midbody of manufacturing specialized membrane such as ultrafiltration membrane, It is also the surface active agent, and midbody of medical anesthetics, lubrication, substitute of blood, plastic etc. The antimony pentafluoride is the catalyst of difluoromethane, namely R32 of refrigerant that is the main product to take the place of chlorofluorocarbons (CFCs). The antimony pentafluoride is also a catalyst in the production of jet fuel and a new pattern of explosive, can also play a role in butyl alkyl to use in improving the gasoline quality.
