Dioxygen difluoride reactions

Potentially explosive reaction with nitric acid + sulfuric acid, bromine trifluoride, nitrosyl chloride + platinum, nitrosyl perchlorate, chromyl chloride, thiotrithiazyl perchlorate, and (2,4,6-trichloro-l, 3,5-triazine + water). Reacts to form explosive peroxide products with 2-methyl-1,3-butadiene, hydrogen peroxide, and peroxomonosulfuric acid. Ignites on contact with activated carbon, chromium trioxide, dioxygen difluoride + carbon dioxide, and potassium-tert-butoxide. Reacts violendy with bromoform, chloroform + alkalies, bromine, and sulfur dichloride. 

SAFETY PROFILE Moderately toxic by inhalation. A severe eye, skin, and mucous membrane irritant. Explodes on contact with dioxygen difluoride. Violent reaction or ignition with borane, diborane, F2. hexafluoroisopropylideneamino lithium, O2. Win react with water or steam to produce toxic and corrosive fumes. Dangerous when heated to decomposition it emits highly toxic fumes of F" and PO. See also HYDROFLUORIC ACID, FLUORIDES, and PHOSPHORUS PENTAFLUORIDE. 

If Xep4 is desired, a different reaction can be used. For example, Xep4 can be made from the reaction of xenon gas with dioxygen difluoride. The reaction also produces oxygen gas. 

PERCLENE (127-18-4) or PERCLOROETILENO (Spanish) (127-18-4) see perchloroethylene. PERFLUROETHYLENE (116-14-3) FjC=CFj Highly reactive, thermally unstable, flammable gas (flash point <32°F/<0°C). Explodes underpressure. Able to form unstable peroxides in air. If inhibitor (usually limolene) is not present in adequate concentrations, explosive polymerization may occur above 2025 mm Hg/2.66 bars at normal tenqjerature. Inhibited monomer will explode on contact with iodine pentafluoride and other substances, or in elevated tenperatures. Violent reaction with chloro-peroxytrifluoromethane, difluoromethylene dihypofluorite dioxygen difluoride, halogens, oxidizers, oxygen, sulfur trioxide, triboron pentafluoride. Incompatible with ethylene, hexafluoropropene forms an explosive peroxide. Normal gases date containers when opened and discard after 12 months. 

Dioxygenyl hexafluoroarsenate can be prepared by the reaction between arsenic pentafluoride and dioxygen difluoride or by heating a mixture of arsenic pentafluoride, fluorine, and oxygen. However, photosynthesis, using this latter mixture, appears to be the most convenient method for the preparation of dioxygenyl hexafluoroarsenate. 

It can be obtained by reaction of xenon with excess dioxygen difluoride... 

XeFj can be obtained either by direct fluorinadon or by reaction with dioxygen difluoride. 

XeF, is obtained by heating a mixture of Xe and Fj in the ratio 1 20 at a high pressure or by reaction with dioxygen difluoride at a very low temperature.
