Usage

General Description

1,1,2,2,3-Pentafluoropropane is a fluorocarbon compound classified as a hydrofluorocarbon (HFC). As with many in the HFC group, it has properties that are advantageous for use in refrigeration and other cooling applications. Its chemical formula is C3HF5 and it is a colorless and odorless gas under normal conditions. It is also used in the manufacture of semiconductors and as a fire extinguishing agent due to its non-flammability. HFCs like 1,1,2,2,3-Pentafluoropropane are prominent in discussions about the environment, as they are recognized as potent greenhouse gases that contribute significantly to global warming.

PROCESSES FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE AND/OR 1,2,3,3-TETRAFLUOROPROPENE

A process is disclosed for making CF3CF=CH2 or mixtures thereof with CHF2CF=CHF. This process involves (a) reacting CHCI2CF2CF3, and optionally CHCIFCF2CCIF2, with H2 in the presence of a catalytically effective amount of a hydrogenation catalyst to form CH3CF2CF3 and, when CHCIFCF2CCIF2 is present, CH2FCF2CHF2; (b) dehydrofluorinating CH3CF2CF3, and optionally any CH2FCF2CHF2, from (a) to form a product mixture including CF3CF=CH2 and, if CH2FCF2CHF2 Js present, CHF2CF=CHF; and optionally (c) recovering CF3CF=CH2, or a mixture thereof with CHF2CF=CHF from the product mixture formed in (b) and/or (d) separating at least a portion of any CHF2CF=CHF in the product mixture formed in (b) from the CF3CF=CH2 in the product mixture formed in (b).

Perfluorination of Allene Derivatives by Direct Fluorination

Perfluoropropane was prepared from allene with elemental fluorine in the presence of sodium fluoride in 84percent yield for the first time.The reaction of allene with elemental fluorine afforded 2,2-difluoropropane in the absence of sodium fluoride.Methoxyallene and cyanoallene were perfluorinated with elemental fluorine in the presence of sodium fluoride to give heptafluoropropyl trifluoromethyl ether and heptafluoropropyl cyanide in good yields respectively.In addition, the direct fluorination of cyanoallene in the presence of cesium fluoride afforded N,N-difluorononafluorobutylamine in 95percent yield.
