| titleOfInvention | Method to improve 1,1,3-trichloropropene and/or 3,3,3-trichloropropene selectivity during the dehydrochlorination of 1,1,1,3-tetrachloropropane |
| abstract | 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 dehydrochlorination of 1,1,1,3-tetrachloropropane (HCC-250fb). In normal practice, FeCl 3 is used as the catalyst for the dehydrochlorination of HCC-250fb to produce 1,1,3-trichloropropene and/or 3,3,3-trichloropropene. The present invention demonstrates that when using FeCl 3 as the catalyst for 1,1,1,3-tetrachloropropane dehydrochlorination, 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 dehydrochlorination reaction system, inhibits the formation of these high boiling compounds and improves selectivity to the desired product. |
