Usage

General Description

1,1,1,2,3-Pentafluoropropane is a chemical compound with the molecular formula C3H2F5. It is a colorless, odorless gas that is used as a refrigerant and as a propellant in aerosol sprays. It is also known by the trade name HFC-245fa. 1,1,1,2,3-Pentafluoropropane has low toxicity and is non-flammable, making it a safer alternative to older refrigerants such as CFCs and HCFCs. However, it is considered a greenhouse gas and has a high global warming potential, so efforts are being made to find more environmentally friendly alternatives.

METHOD FOR PREPARING 2,3,3,3-TETRAFLUOROPROPENE AND 1,3,3,3-TETRAFLUOROPROPENE

A method for preparing 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene, including: providing a first reactor including a first section, a second section, and a third section, with each section being filled with different catalysts, preheating hexafluoropropylene and hydrogen, and introducing the hexafluoropropylene and the hydrogen to the first reactor to yield a first mixture including: 1,1,1,2,3-pentafluoropropane, 1,1,1,2,3,3-hexafluoropropane, and hydrogen fluoride; introducing the first mixture to a first distillation column to yield 1,1,1,2,3,3-hexafluoropropane at a top of the first distillation column and 1,1,1,2,3-pentafluoropropane and hydrogen fluoride at a bottom of the first distillation column, recycling the 1,1,1,2,3,3-hexafluoropropane to a lower part of the first section of the first reactor, and introducing the 1,1,1,2,3-pentafluoropropane and the hydrogen fluoride to a second reactor to yield a second mixture including: 2,3,3,3-tetrafluoropropene, 1,3,3,3-tetrafluoropropene, hydrogen fluoride, and 1,1,1,2,3-pentafluoropropane; and performing water washing, alkaline washing, drying, and distillation on the second mixture to yield 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene.

Method and apparatus for continuously producing 1,1,1,2,3-pentafluoropropane with high yield

A method and apparatus for method of continuously producing 1,1,1,2,3-pentafluoropropane with high yield is provided. The method includes (a) bringing a CoF3-containing cobalt fluoride in a reactor into contact with 3,3,3-trifluoropropene to produce a CoF2-containing cobalt fluoride and 1,1,1,2,3-pentafluoropropane, (b) transferring the CoF2-containing cobalt fluoride in the reactor to a regenerator and bringing the transferred CoF2-containing cobalt fluoride into contact with fluorine gas to regenerate a CoF3-containing cobalt fluoride, and (c) transferring the CoF3-containing cobalt fluoride in the regenerator to the reactor and employing the transferred CoF3-containing cobalt fluoride in Operation (a). Accordingly, the 1,1,1,2,3-pentafluoropropane can be continuously produced with high yield from the 3,3,3-trifluoropropene using a cobalt fluoride (CoF2/CoF3) as a fluid catalyst, thereby improving the reaction stability and readily adjusting the optimum conversion rate and selectivity.

HYDROGEN FLUORIDE-HFC-254EB AZEOTROPE AND ITS USES

Described is a process for separating 1,1,1,2-tetrafluoropropane and hydrogen fluoride from a mixture comprising 1,1,1,2-tetrafluoropropane, 1,1,1,2,3-pentafluoropropane and hydrogen fluoride comprising: subjecting said 1,1,1,2-tetrafluoropropane, 1,1,1,2,3-pentafluoropropane and hydrogen fluoride mixture to a distillation step, forming a column distillate composition comprising an azeotropic or near-azeotropic composition of said 1,1,1,2-tetrafluoropropane and hydrogen fluoride, and a bottoms composition of 1,1,1,2,3-pentafluoropropane. The column distillate may optionally be made essentially free of 1,1,1,2,3-pentafluoropropane and the column bottoms composition may optionally be made essentially free of HF. Also described is a process for separating 1,1,1,2-tetrafluoropropane and hydrogen fluoride from a mixture of 1,1,1,2-tetrafluoropropane and hydrogen fluoride. Also described are azeotropic and azeotrope-like compositions comprising 1,1,1,2-tetrafluoropropane and hydrogen fluoride.
