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.

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.

Study on the Preparation of Cr-based Catalysts Doped by Zn using Sol–Gel Auto-Combustion Method and Its Application for Synthesis of 1-Chloro-2,3,3,4,4,5,5-heptafluorocyclopentene

High-surface-area chromium-based catalysts in the presence of a small amount of zinc were prepared via a sol–gel auto-combustion method using chromic nitrate, zinc nitrate, and citric acid. First, the auto-combustion behavior of the dried gel was investigated by derivative thermogravimetry and (DTG)-TG and infrared (IR) techniques. The results revealed that the dried gel exhibited self-propagating combustion properties. Second, the as-burnt powders were characterized by IR, X-ray diffraction (XRD), Brunauer–Emmett–Teller analysis (BET), and scanning electron microscopy (SEM). The findings showed that the gels were directly converted into CrZn-O nanoparticles with high surface area during the auto-combustion process. Third, the pre-fluorination Cr-Zn catalysts were characterized by XRD, BET, SEM, X-ray photoelectron spectroscopy (XPS), and Fourier transform (FT)-IR spectroscopy of pyridine adsorption techniques. It was found that the presence of zinc led to significant structural changes in the catalyst, the particle size was smaller, the surface area became larger, and more active sites appeared. Finally, the catalytic activities of the samples were tested for the fluorination of 1,2-dichlorohexafluorocyclopentene (1,2-F6) with anhydrous hydrogen fluoride. The obtained results indicated that the pre-fluorination activated Cr-Zn catalysts prepared by this sol–gel auto-combustion method exhibited high efficiency in the synthesis of cyclic hydrofluorocarbons.
