Abstract
Disclosed is a process for producing highly pure chlorinated alkane in which a chlorinated alkene is contacted with chlorine in a reaction zone to produce a reaction mixture containing the chlorinated alkane and the chlorinated alkene, and extracting a portion of the reaction mixture from the reaction zone, wherein the molar ratio of chlorinated alkane:chlorinated alkene in the reaction mixture extracted from the reaction zone does not exceed 95:5.

A highly pure chlorinated alkane composition, as a feedstock for use in the synthesis of a chlorinated alkene, or a fluorinated alkane or fluorinated alkene or chlorofluorinated alkene or mixtures thereof, wherein the composition has been obtained by feeding a chlorinated alkene into a reaction zone and contacting it with chlorine in said reaction zone to produce a reaction mixture containing the chlorinated alkane and the chlorinated alkene, and extracting a portion of the reaction mixture from the reaction zone, wherein the molar ratio of chlorinated alkane:chlorinated alkene in the reaction mixture extracted from the reaction zone does not exceed 95:5, and wherein the composition obtained from the reaction mixture comprises:
- the chlorinated alkane product in amounts of at least about 99.7%, at least about 99.8%, at least about 99.9%, or at least about 99.95%, and one or more of the following:
- oxygenated organic compounds in amounts of less than about 500 ppm, about 250 ppm or less, about 100 ppm or less, about 50 ppm or less, or about 10 ppm or less,
- isomers of the chlorinated alkane of interest amounts less than about 500 ppm or less, about 250 ppm or less, or about 100 ppm or less,
- non-isomeric alkane impurities in amounts of less than about 500 ppm, about 250 ppm or less, or about 100 ppm or less,
- chlorinated alkenes in amounts of less than about 500 ppm, about 250 ppm or less, about 100 ppm or less, or about 50 ppm or less,
- water in amounts of less than about 500 ppm, about 250 ppm or less, about 100 ppm or less or about 50 ppm or less,
- inorganic compounds of chlorine in amounts of about 100 ppm or less, about 50 ppm or less, about 20 ppm or less or about 10 ppm or less,
- brominated organic compounds in amounts of about 100 ppm or less, about 50 ppm or less, about 20 ppm or less or about 10 ppm or less, and/or
- iron in amounts of about 100 ppm or less, about 50 ppm or less, about 20 ppm or less, about 10 ppm or less or about 5 ppm or less.
A chlorinated alkane feedstock composition for use in the synthesis of a chlorinated alkene, or a fluorinated alkane or fluorinated alkene or chlorofluorinated alkene or mixtures thereof, wherein the composition comprises:

- oxygenated organic compounds in amounts of less than about 500 ppm, about 250 ppm or less, about 100 ppm or less, about 50 ppm or less, or about 10 ppm or less,
- isomers of the chlorinated alkane of interest amounts less than about 500 ppm or less, about 250 ppm or less, or about 100 ppm or less,
