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.

1-19. (canceled)
A highly pure chlorinated alkane composition, wherein the composition comprises:
- the chlorinated alkane in amounts of at least about 99.5%, and the following:
- oxygenated organic compounds in amounts of less than about 500 ppm,
- isomers of the chlorinated alkane in amounts of less than about 500 ppm,
- non-isomeric alkane impurities in amounts of less than about 500 ppm,
- chlorinated alkenes in amounts of less than about 500 ppm,
- water in amounts of less than about 500 ppm,
- inorganic compounds of chlorine in amounts of less than about 100 ppm,
- brominated organic compounds in amounts of less than about 100 ppm, and
- iron in amounts of less than about 500 ppm.
A highly pure chlorinated alkane composition wherein the composition comprises
- the chlorinated alkane in amounts of at least about 99.5%, and
- oxygenated organic compounds in amounts of less than about 500 ppm.
A process for removing oxygenated organic compounds from a chlorinated alkane rich product comprising a chlorinated alkane, a chlorinated alkene and oxygenated organic compounds, comprising feeding the chlorinated alkane rich product into an aqueous treatment zone, contacting the chlorinated alkane rich product with an aqueous medium to produce a mixture and extracting i) an organic phase from that mixture or ii) a chlorinated alkane stream from that mixture, the organic phase/chlorinated alkane stream comprising reduced levels of oxygenated organic compounds as compared to the chlorinated alkane rich product fed into the aqueous treatment zone.
