The third method is a process developed by Central Glass Co. Ltd using the gas-solid reaction of ammonium complex of metal fluoride with fluorine [35]. During experiments designed to prepare various perhalomethanes, Haszeldine and Iserson frequently found carbonic chloride fluoride amongst the products isolated from the co-pyrolysis of carbonic difluoride and phosgene over carbon powder at temperatures of 400–450 °C <57JA5801>. CC BY-SA. If the reaction takes place instantaneously and the volatility of the reaction products is high enough, the volatile compounds leave the etch surface quickly and take away the material to be etched, yielding isotropic etching behavior. The chemical reaction could be given as below. Finally, by an industrial gas phase process it is claimed that the reaction of thionyl fluoride with phosgene over a Lewis acid catalyst at 300–400 °C can be made to yield either carbonic difluoride or carbonic chloride fluoride by varying molar ratios and conditions.

As epoxy compounds containing an inner 1,2-epoxy group there are suitable epoxidized diolefins, dienes, or cyclic dienes, such as 1,2,5,6-diepoxy hexane, 1,2,4,5-diepoxy cyclohexane, dicyclopentadiene diepoxide, dipentene diepoxide, vinyl cyclohexane diepoxide, epoxidized diolefinically unsaturated carboxylic acid esters, such as methyl-9,10,12,13-diepoxy stearate or the dimethyl ester of 6,7,10,11-diepoxyhexadecane-1,16-dicarboxylic acid. Boron Trifluoride Structure PTFE is converted into a lower-MW polymer in the form of a fine powder by subjecting the fluoropolymer to contact reaction with a gas comprising molecular fluorine or a suitable fluoride, such as nitrogen trifluoride or xenon difluoride at a temperature between the melting temperature of the fluoropolymer and 600 °C, extracting a hot reaction gas produced by the contact reaction from the reactor and cooling the extracted reaction gas to a temperature below 100 °C. CC BY-SA 3.0. https://commons.wikimedia.org/wiki/File:Hybrydyzacja_sp2.svg In company with all other carbonic dihalides, it is extremely toxic. Other names which have been used for this compound are carbonyl chloride fluoride, carbonyl chlorofluoride, chlorocarbonyl fluoride and chlorofluorophosgene. For example, nitrogen trifluoride (NF3) is a stable gas at room temperature and has a strong oxidation power at higher temperatures [3–5]. The resulting mixture was mixed with 10 g of the diglycidyl ether of poly (propylene glycol) of Example 4, 5 g of phenyl glycidyl ether and 4 g of boron trifluoride-ethyl amine and the resulting liquid was filled with 30 g of dry talc. The epoxide resin component may contain other materials such as polymers including polybutadiene rubber for instance, for improving the flexibility of the cured polymer. Many metals form trifluorides, such as iron, the rare-earth elements, and the metals in the aluminium and scandium columns of the periodic table.

The characteristics of both structural features and physical–chemical properties of the formed hydroxyfluorides can be related to the different experimental parameters, in particular the nature of precursor and solvents and the F/metal molar ratio, as shown in Table 1 for aluminum hydroxyfluorides. The reaction can be written19,20 as, In the second step, a postfluorination treatment, using gaseous chlorofluorocarbon (CFC) or anhydrous HF as fluorinating agents, replaces the remaining alkoxy groups by fluoride anions to obtain pure HSA fluoro-compounds.21. HF, 1 mole of desired NF3 is produced with 5 moles of HF as by-products. ClF 3 is a poisonous, colorless, corrosive, extremely reactive gas with a sweet and suffocating pungent type of odor. Bromotrifluoromethane, (carbon monobromide trifluoride) Bromine trifluoride, BrF 3; Chlorine trifluoride, ClF 3; Chromium trifluoride; Cobalt trifluoride; Diethylaminosulfur trifluoride (DAST) is the organosulfur compound with the formula Et 2 NSF 3; Fluoroform, (trifluoromethane) Gallium trifluoride; Gold trifluoride; Indium trifluoride For decontamination and sterilization applications in health care and in the biomedical industry, the most common gases are hydrogen peroxide (H2O2), ethylene oxide (EtO, C2H4O), chlorine dioxide (ClO2), and formaldehyde (CH2O).
