| titleOfInvention | Method for preparing hexafluorobutadiene and 1,2-dichlorohexafluorocyclobutane |
| abstract | In the process for producing hexafluorobutadiene simultaneously with the yield of 1,2-dichlorohexafluorocyclobutane, the initial chlorotrifluoroethylene is pyrolyzed at a temperature in the range of 505 to 600 ° C, and the resulting pyrolysis product Condensation and fractionation in the temperature range of 0 ° C. to −10 ° C. separate fractions having a boiling point of 59.0 to 59.5 ° C. containing 1,2-dichlorohexafluorocyclobutane. Fractions of boiling point 63.5 to 64 ° C. containing 1,2-dichlorohexafluorobutene-3 are subjected to dechlorination in polar solvents in the temperature range of 37 ° C. to 50 ° C.n n n 1,2-dichlorohexafluorocyclobutane, hexafluorobutadiene, pyrolysis, dechlorination |
