REACTIONS OF PENTAFLUOROTELLURIUM HYPOHALITES WITH FLUOROOLEFINS

Both pentafluorotellurium hypochlorite, TeF5OCl, and hypofluorite, TeF5OF, react with fluoroolefins to form TeF5O- containing fluorocarbons, a new class of compounds.In the case of TeF5OF, yields of the adducts are high (60-86percent) but are lower (22-30percent) with TeF5OCl.In the latter case extensive chlorofluorination of the olefin occurs.Olefins studied include CF2=CF2, CF3CF=CF2, CF2=CFCl, and perfluorocyclopentene.Details of the synthesis and characterization of these new fluorocarbons are presented.

From hypochlorites to perfluorinated dialkyl peroxides

The synthesis and characterization of the new perfluorinated hypochlorite, undecafluoro-tert-pentyl hypochlorite, (C2F5)(F3C)2COCl, is reported. Its gas-phase infrared, UV/Vis and NMR spectra have been recorded and its spectroscopic properties are discussed and compared with quantum-chemical predictions and those of other known perfluorinated hypochlorites such as RFOCl [RF = F3C, (F3C)3C, (C2F5)(F3C)2C]. A synthetic route to otherwise difficult to access perfluorinated dialkyl peroxides, RFOORF, is also provided by low-temperature photolysis of the corresponding hypochlorite.

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.

Catalytic conversion of hydrofluoroalkanol to hydrofluoroalkene

Methane is used as the selective dehydrating agent for the production of 2,3,3,3-tetrafluoro-1-propene (R1234yf) from 2,2,3,3,3-pentafluoro-1-propanol. Supported transition metal catalysts are prepared and used for this reaction with high activity. Almost 58% selectivity to R1234yf is obtained at an alcohol conversion level of 60% using unsupported Ni-mesh as the catalyst. Pd and Pt show almost similar level of conversion; however, the selectivity to the desired product is low. The activity of the metal catalyst was found to be a function of the type of support material, activated carbon showing better activity than alumina. Different important process parameters such as temperature, pressure, and contact time are studied to optimize the process. High pressure and temperature are deleterious to the rate of 1234yf formation; yet, the highest yield to 1234yf is obtained while performing a reaction at 494° C. with a contact time of 23 sec.

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.
