摘要： This invention relates to a method to improve 1, 1,3-trichloropropene selectivity in HCC-250fb (1,1,1,3-tetrachloropropane) dehydrochlorination. In normal practice, FeCl3 is used as the catalyst for the dehydrochlorination of HCC-250fb to produce 1,1,3-tri-chloropropene. In this invention as source of water is added into the reaction system to inhibit the formation of high boiling compounds such as pentachlorocyclohexene and/or hexachlorocyclohexane. Once source of water is H
2 O itself. Another source of water is one or more hydrated metal halides.-

摘要： In the halogenation reaction of olefin/halo-olefin (i.e., organic), an excess amount of halogen gas (fluorine, chlorine, vaporized bromine and iodine, or their combination) is normally used in order to achieve as complete as possible conversion of the organic. In a conventional process, the excess halogen gas in the off-gas stream is scrubbed by caustic solution which increases the consumption of halogen and generates waste for disposal. The present invention provides a novel process to recover and reuse the excess halogen gas and thus reduce the operating cost of the process.

摘要： Embodiments of a fluidized bed fluorination reactor are provided, as are embodiments of a fluidized bed reactor and embodiments of a fluorination method carried-out utilizing a fluidized bed fluorination reactor. In one embodiment, the fluidized bed fluorination reactor includes a source of fluorine gas, a reaction vessel, a windbox fluidly coupled to the source of fluorine gas, and a conical gas distributor fluidly coupled between the reaction vessel and the wmdbox. The conical gas distributor has a plurality of gas flow openings directing fluorine gas flow from the windbox into the fluorination reaction vessel during the fluorination process.

摘要： This invention relates to a method to improve 1,1, 3 -trichloropropene (HCC- 1240za) and/or 3,3,3-trichloropropene (HCC-1240zf) selectivity in the dehydrochlormation of 1,1,1,3-tetrachloropropane (HCC-250fb). In normal practice, FeCl3 is used as the catalyst for the dehydrochlormation of HCC-250fb to produce 1,1,3- trichloropropene and/or 3,3,3-trichloropropene. The present invention demonstrates that when using FeCl3 as the catalyst for 1,1,1,3-tetrachloropropane dehydrochlormation, the reaction product contains significant amounts of high boiling compounds, such as pentachlorocyclohexene and/or hexachlorocyclohexane species. The addition of one or more UV-stabilizer and/or anti-oxidant compounds, or mixtures thereof, into the dehydrochlormation reaction system, inhibits the formation of these high boiling compounds and improves selectivity to the desired product.
