2,3-二氯-1,1,1,4,4,4-六氟丁烷

反应条件: temp:260.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2,3-Dichlorohexafluorobut-2-ene 300 g) and iodine 150 g) were charged into a 1 liter stirred autoclave. The autoclave was sealed, cooled and evacuated. It was then charged with hydrogen to 500 psi at room temperature. The autoclave was heated to 260° C. and the hydrogen pressure was increased to 1500 psi. The temperature was held at 260° C. with periodic additions of hydrogen to maintain a pressure of 1500 psi. After 15 hours no more hydrogen was being consumed by the reaction. The temperature was held for an additional six hours and then the clave was cooled and the gases were vented. The liquid was washed with water, saturated sodium thiosulfate solution, and then analyzed by GC/IR. Analysis showed that it contained 0.5% 1,1,1,4,4,4-hexafluorobutane, 85% 2 chloro-1,1,1,4,4,4-hexafluorobutane, and 13.5% of 2,3-dichloro-1,1,1,4,4,4-hexafluorobutane as two isomers. Distillation on a concentric tube column gave 78 g of 2-chloro-1,1,1,4,4,4-hexafluorobutane, and 25 g of 2,3 -dichloro-1,1,1,4,4,4-hexafluorobutane as two isomers. The autoclave was sealed cooled evacuated It was then charged with hydrogen to 500 psi at room temperature the hydrogen pressure was increased to 1500 psi was held at 260° C. with periodic additions of hydrogen to maintain a pressure of 1500 psi After 15 hours no more hydrogen was being consumed by the reaction the clave was cooled The liquid was washed with water, saturated sodium thiosulfate solution Distillation on a concentric tube column
