General Description

1,1,1,2,2-Pentafluoropropane, also known as HFC-245ca, is a hydrofluorocarbon with the chemical formula C3HF5. 1,1,1,2,2-PENTAFLUOROPROPANE is a colorless gas and is typically used in refrigeration systems, fire extinguishing systems, or as a blowing agent in some insulation materials. 1,1,1,2,2-Pentafluoropropane has a low boiling point and is non-flammable, making it an ideal choice for these applications. It has zero ozone depletion potential, but it is a potent greenhouse gas with potential effects on global warming. Due to its environmental impact, its use has been curtailed in some regions. Despite this, it is still in use in many areas for its effective cooling properties and relative safety in operation.

METHOD

A method for activating a catalyst comprises the steps of: a) optionally drying the catalyst at a temperature of from 100°C to 400°C; b) treating the catalyst with a composition comprising HF at a temperature of from 0°C to about 500°C; c) treating the catalyst with a composition comprising an oxidant and optionally HF at a temperature of from about 100°C to about 500°C.

Activation of pentafluoropropane isomers at a nanoscopic aluminum chlorofluoride: Hydrodefluorination versus dehydrofluorination

The hydrofluorocarbon 245 isomers, 1,1,1,3,3-pentafluoropropane, 1,1,1,2,2- pentafluoropropane, and 1,1,1,2,3-pentafluoro-propane (HFC-245fa, HFC-245cb, and HFC-245eb) were activated through C-F bond activations using aluminium chlorofluoride (ACF) as a catalyst. The addition of the hydrogen source Et3SiH is necessary for the activation of the secondary and tertiary C-F bonds. Multiple C-F bond activations such as hydrodefluorinations and dehydrofluorinations were observed, followed by hydroarylation and Friedel-Crafts-type reactions under mild conditions.

METHOD FOR PRODUCING AND PURIFYING 2,3,3,3-TETRAFLUOROPROPENE

The invention relates to a process for producing 2,3,3,3-tetrafluoropropene performed using a starting composition, comprising the steps of placing the starting composition in contact with HF, in the presence of a catalyst, to produce a composition A comprising 2,3,3,3-tetrafluoropropene (1234yf), intermediate products B consisting of 2-chloro-3,3,3-trifluoropropene (1233xf), 1,1,1,2,2-pentafluoropropane (245cb), and side products C consisting of E-1-chloro-3,3,3-trifluoro-1-propene (1233zdE), trans-1,3,3,3-tetrafluoro-1-propene (1234zeE) and 1,1,1,3,3-pentafluoropropane (245fa); recovery of said composition A and purification thereof to form and recover a first stream comprising 2,3,3,3-tetrafluoropropene (1234yf) and one or more streams comprising 2-chloro-3,3,3-trifluoropropene (1233xf) and/or 1,1,1,2,2-pentafluoropropane (245cb); recycling into step a) of said one or more streams comprising 2-chloro-3,3,3-trifluoropropene (1233xf) and/or 1,1,1,2,2-pentafluoropropane (245cb).
