Usage

General Description

1,2,3-Trichloropentafluoropropane is a chemical compound with the molecular formula C3Cl3F5. It is a colorless, odorless gas that is used as a refrigerant and as a blowing agent for foam production. The compound is highly volatile and non-flammable, making it useful for a variety of industrial applications. However, 1,2,3-Trichloropentafluoropropane is also a potent greenhouse gas and has been banned for use in many countries due to its negative environmental impact. Exposure to the compound can cause respiratory and central nervous system effects in humans, and it is considered a hazardous substance. Due to its environmental and health risks, the production and use of 1,2,3-Trichloropentafluoropropane are strictly regulated.

Thermal chlorofluorination of propyne and propadiene II

Propyne and propadiene have been previously reported to readily undergo vapor phase catalyzed chlorofluorination at temperatures to 285 °C to form C3F4Cl4 mixtures that are primarily CFCl2-CF2-CFCl2. Continued fluorination at temperatures up to 485 °C produce the rearranged C3F6Cl2 isomers CF3-CCl2-CF3 and CF2Cl-CFCl-CF3.

Synthesis of > and Some Chlorofluoropropenes

The starting substances C3Cl5F3 (1) and C3Cl4F4 (2) prepared earlier by the addition of CCl3F with CClF=CClF and/or CF2=CClF were utilized for the synthesis of chlorofluoropropenes by means of fluorination, reduction of C-Cl bonds in halogenopropanes, and final dehalogenation, all the reactions being performed at atmospheric pressure.The reaction conditions permit laboratory scale production.The contents of the isomeric admixtures in the resultant products were determined by NMR spectroscopy.The starting halogenopropanes 1, 2 represent mixtures of isomers, but in course of the individual synthetic steps the content of the main isomer was generally increased.In comparison with previously used syntheses, our procedure proves advantageous for the synthesis of "perfluoroallylchloride" (9a, isomer purity 95percent).Using this procedure a number of halogenopropanes were prepared and dechlorinated to give the corresponding halogenopropenes (isomer purity percent): CClF2-CClF-CCl2F (2a, 87), CF3-CClF-CCl3 (2b, 78), CClF2-CClF-CClF2 (3a, 87), CF3-CClF-CCl2F (3b, 90), CF3-CClF-CHCl2 (5a, 90), CF3-CClF-CHClF (6a, 73), CClF2-CF=CClF (8a, 93), CF3-CF=CCl2 (8b, 84), 9a, CF3-CF=CClF (9b, 86) and CF3-CF=CHCl (11a, 84).The minor isomers in substance 2 yielded products which were isolated after being combined from several preparations: CClF2-CF2-CHCl2 (5b, 84); CClF2-CF=CHCl (10a, 98), which by addition of chlorine yielded CClF2-CClF-CHCl2 (4a, 95).The NMR spectra of all the major and minor products, excluding perhalogenopropanes, are listed.
