The behaviour of chlorofluoroethanes on β-aluminium(III) fluoride: A [ 36Cl ] radiotracer study

A [36Cl] radiotracer study of the behaviour of 1,1,2-trichlorotrifluoroethane on β-aluminium(III) fluoride at elevated temperature indicates that the isomerisation of CCl2FCClF2 to CCl3CF3 occurs by an intramolecular process. Isomerisation is followed by dismutation of CCl3CF3 to give CCl2FCF3 and CCl3CClF2. In neither reaction, surface Al-Cl groups are formed. The compound CCl3CClF2 undergoes further reaction, readily, apparently also via dismutation processes.

FTIR spectroscopic and reaction kinetics study of the interaction of CF3CFCl2 with γ-Al2O3

The interaction of CF3CFCl2 with γ-Al2O3 has been investigated by a combination of reaction kinetics experiments and FTIR spectroscopic studies. The reaction of fresh γ-Al2O3 with CF3CFCl2 at 573 K resulted in the fluorination of the γ-Al2O3 surface. The reaction also resulted in dehydroxylation of the γ-Al2O3 and an increase in both the number and strength of Lewis acid sites on the surface. The fluorinated γ-Al2O3 was catalytically active for the disproportionation of CF3CFCl2 to CF3CCl3 and CF3CF2Cl at 353 K. Adsorption of CF3CFCl2 on γ-Al2O3 at temperatures between 298 and 523 K resulted in the formation of surface trifluoroacetate species, which were stable up to 573 K. These species are likely to be the intermediates for the complete oxidation of CF3CFCl2 to CO and CO2. The transformation of γ-Al2O3 as a result of the CF3-CFCl2 adsorption and reaction is discussed.

PREPARATION OF CHLOROPENTAFLUOROETHANE FROM DICHLOROTETRAFLUOROETHANE

Gaseous fluorination with hydrogen fluoride at atmospheric pressure of the two isomers CClF2-CClF2 and CCl2F-CF3 was carried out continuously on a chromic oxide based catalyst.The fluorinated derivative, obtained in a yield greater than 90percent, was chloropentafluoroethane.Hexafluoroethane and an isomeric mixture of trichlorotrifluoroethane were obtained as by-products.The latter was recycled with unconverted C2Cl2F4 for further fluorination.Both conversion of C2Cl2F4 and selectivity to the formation of C2ClF5 were affected by temperature, contact time and molar ratio of the reagents.The catalytic activity of chromic oxide was adversely affected by small amounts of water in the hydrogen fluoride.A difference was also observed in the reactivity of the two isomers CCl2F-CF3 and CClF2-CClF2.The formation of C2Cl3F3 as a by-product was due to the disproportionating activity of chromic oxide upon C2Cl2F4.

RADIOTRACERS IN FLUORINE CHEMISTRY. PART IX FLUORINATION OF CHLOROFLUOROETHANES BY CHROMIA CATALYSTS TREATED WITH HYDROGEN FLUORIDE OR HYDROGEN -FLUORIDE

Passage of dichlorotetrafluoroethane isomers or 1,1,2-trichloro-1,2,2-trifluoroethane at temperatures >/= 623 K over chromia catalysts, previously treated with hydrogen fluoride at 623 K, leads to the formation of fluorinated and chlorinated products.Incorporation of fluorine-18 radioactivity in the products is observed when hydrogen -fluoride is used in the catalyst pretreatment, indicating the involvement of a surface fluorinecontaining species.The reactions observed are described in terms of series of F-for-Cl and Cl-for-F halogen exchange reactions occurring at the catalyst surface.

High surface area chromium(III)fluoride – Preparation and some properties

Reaction of hydrated hydrazinium fluorochromate(III), [N2H6][CrF5]·H2O, with fluorine (F2)in anhydrous hydrogen fluoride (aHF)medium at room temperature yields completely amorphous CrF3-based materials with exceptionally high specific surface areas of 180–420 m2 g?1 (HS-CrF3). The stepwise reaction starts with the oxidative decomposition of the cationic part of the precursor with F2 that gives a CrF3 intermediate with low surface area. In the following step, part of Cr3+ is oxidized to Cr>3+, and in the presence of residual H2O/[H3O]+ species Cr>3+ fluoride oxides are formed. Formation of volatile chromium compounds, mainly CrO2F2, is apparently the key step in HS-CrF3 formation. Removal of these components from the final product reduces the oxygen content, and generates microporosity. The HS-CrF3 materials are completely amorphous with a bulk composition that is close to stoichiometric CrF3. Small amounts of Cr>3+ and oxygen in the final product very likely originate from the retained non-volatile CrOF3. The HS-CrF3 materials are Lewis acids and exhibit a high reactivity towards chlorofluorocarbons (CFCs)evidenced by substantial F/Cl exchange between CFCs and the solid fluoride. High reactivity of these new materials can be ascribed to their nanoscopic nature, exceptionally high surface area, and low levels of impurities. As such, they represent an interesting new class of benchmark fluoride materials applicable in fluorocarbon chemistry.

Nitrogen trifluoride as an oxidative co-reagent in high temperature vapor phase hydrofluorinations

Nitrogen trifluoride (NF3) has proven to be a useful additive in high temperature vapor phase hydrofluorination reactions of chlorocarbons. The activity of chromium-based catalysts is maintained by introducing a co-stream of NF3 into the reagent chlorocarbon and HF stream. NF3 is a desirable additive instead of O2 as there is no water generation due to its use.
