Manufacturing method of 1,2-dichlorohexafluorocyclopentene

Disclosed is a manufacturing method of 1,2-dichlorohexafluorocyclopentene. The first reaction uses dicyclopentadiene as a starting material and nitrogen gas or another inert gas as a diluting agent in a gas-phase thermal cracking reaction to obtain cyclopentadiene. The second reaction uses cyclopentadiene as a starting material in a liquid phase chlorination reaction with chlorine gas to obtain 1,2,3,4-tetrachlorocyclopentane. The third reaction uses 1,2,3,4-tetrachlorocyclopentane as a starting material in a gas-phase chlorination and fluorination reaction with hydrogen fluoride and chlorine gas in the presence of a chromium-based catalyst to obtain 1,2-dichlorohexafluorocyclopentene. The method uses easily acquired starting material and a stable fluorination catalyst, provides a high yield for a target product, and is applicable for large-scale continuous gas-phase production of 1,2-dichlorohexafluorocyclopentene.

Industrial production method for perfluorocyclopentene

The invention discloses an industrial production method for perfluorocyclopentene, and belongs to the field of fine chemical intermediate synthesis. Cyclopentene, chlorine and pyridine hydrofluoride which are used as raw materials undergo high-temperature chlorination in a solvent sulfolane to obtain octachlorocyclopentene, and the octachlorocyclopentene and pyridine hydrofluoride undergo high-temperature fluorination substitution to obtain the perfluorocyclopentene. Residues obtained after the separation of the product undergo reduced pressure distillation to obtain the solvent sulfolane which can be reused. The method allows the product yield to reach 45-55%, the product content to be more than 99%, the water content to be less than 0.1% and the chloride ion content to be less than 0.1%. The method has the advantages of no pollution in the production process, green production process, high yield, simple steps, facilitation of the reduction of the production cost, high product purity, and facilitation of later application.
