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.

MANUFACTURING METHOD OF 1-CHLOROHEPTAFLUOROCYCLOPENTENE

PROBLEM TO BE SOLVED: To provide a method for manufacturing 1-chloroheptafluorocyclopentene at high yield under a moderate reaction condition. SOLUTION: A manufacturing method of 1-chloroheptafluorocyclopentene includes conducting a gas phase reaction of a raw material and hydrogen fluoride at 290-410°C for 15-40 sec. in presence of a burned body catalyst. The raw material contains at least one of 1,3-dichlorohexafluorocyclopenetene and 1,4-dichlorohexafluorocyclopenetene. The burned body catalyst has Cr, Zr and one or more kind of metal selected from Mg, Ni, Al, Fe, La, Sm, Co, W and Mo. A ratio of the substance quantity of the hydrogen fluoride to the substance quantity of 1,3-dichlorohexafluorocyclopenetene or 1,4-dichlorohexafluorocyclopenetene is preferably 20-50.

Method for preparing halogenated pentacyclic olefin by gas-phase isomerization reaction

The invention relates to a method for preparing halogenated pentacyclic olefin by gas-phase isomerization reaction. The method comprises the following steps of: by adopting the halogenated pentacyclic olefin C5HxFyClz as a material, under the existence of an isomerization catalyst, generating the gas-phase isomerization reaction to obtain isomers of the halogenated pentacyclic olefin, wherein X is an integer from 0 to 2, Y is an integer from 4 to 7, Z is an integer from 0 to 4, the sum of X and Y and Z is 8, and the isomerization catalyst is prepared by adopting at least one of lithium fluoride, potassium fluoride, sodium fluoride, rubidium fluoride or cesium fluoride as an active component and loading the active component on at least one of carriers such as aluminium fluoride, magnesium fluoride, iron fluoride, chromium fluoride and zinc fluoride. The method has the advantages that the material is easy to obtain, the isomerization catalyst is low in price, the yield of the isomer is higher, and the method is applicable to large-scale preparation of the isomers of the halogenated pentacyclic olefin by gas-phase reaction.
