Bromine trifluoride, azide

Various alkyl and aryl azides have been transformed into the corresponding nitriles using bromine trifluoride in moderate to good yields (30-60%).25 The reaction is general and gives positive results with aliphatic, aromatic, cyclic, functionalized, and optically active azides. Two alternative mechanisms have been proposed. 

CARBONIC ACID, BARIUM SALT (513-77-9) BaCOj Noncombustible solid. The aqueous solution is basic. Dissolves in most acids except sulfuric acid with release of CO2 gas. This could be dangerous in a confined space. Incompatible with finely divided alxuninum bromine trifluoride fluorine, 2-furanpercarboxylic acid magnesium, oxidizers, sodium azide silicon strong alkalis. Decomposes above 2372°F/1300°C, releasing COj and soluble barium salts including barium oxide. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or CO2 extinguishers. 

TIN or TIN POWDER (7440-31-5) Sn Finely divided material is combustible and forms explosive mixture with air [autoignition temp (dust cloud) 1166°F/630°C]. Contact with moisture in 911 forms tin dioxide. A reducing agent the powder is very reactive. Violent reaction with strong acids, strong oxidizers, ammonium perchlorate, ammonium nitrate, bis-o-azido benzoyl peroxide, bromates, bromine, bromine pentafluoride, bromine trifluoride, bromine azide, cadmium, carbon tetrachloride + water, chlorine, chlorine monofluoride, chlorine nitrate, chlorine pentafluoride, chlorites, copper(II) nitrate, dimethylarsinic acid, fluorine, hydriodic acid, iodine heptafluoride, nitrosyl fluoride, oxygen difluoride, perchlorates, perchloroethylene, potassium dioxide, phosphorus pentoxide, sulfur, sulfur dichloride, turpentine (fire or explosion). 

ARSENIC (7440-38-2) Finely divided material forms explosive mixture with air. Decomposes on contact with acids or acid fumes, emitting fumes of arsenic. Contact of dust or powder with strong oxidizers can cause ignition or explosion. Violent reaction with bromine azide, bromine pentafluoride, bromine trifluoride, dichlorine oxide, hypochlorous acid, nitrogen trichloride, tribromamine hexaammoniate, nitrogen oxyfluoride, potassium chlorate, potassium dioxide, powdered rubidium, silver fluoride.

Forms heat- or shock-sensitive compounds with ammonia, silver azide, potassium, sodium, oxygen difluoride. Incompatible with aluminum-titanium alloy, barium acetylide, ethanol, formamide, halogens, mercmic oxide, mercurous chloride, oxygen, pyridine, pyrogallic acid, salicylic acid sodium hydride, sodium salicylate, sulfides, and other materials. 

STIBIUM (7440-36-0) Dust or powder forms explosive mixture with air. Reacts violently with strong oxidizers and acids, especially halogenated acids, producing toxic stibine gas (antimony hydride). Reacts violently with ammonium nitrate, bromine, bromine azide, bromine trifluoride, bromoazide, chloric acid, chlorine, chlorine monoxide, chlorine trifluoride, dichlorine oxide, disulfur dibromide, fluorine, halogens, iodine, iodine pentafluoride, nitrosyl fluoride, nitryl fluoride, potassium dioxide, potassium nitrate, potassium permanganate, potassium peroxide, sodium nitrate, sodium peroxide. Forms explosive A-chlorodimethylamines with chloric and perchloric acid. 

EXPLOSION and FIRE CONCERNS flammable in the form of dust when exposed to heat or flame when heated or on contact with acid or acid fumes, it emits highly toxic fumes dangerous when water solutions of arsenicals are in contact with active metals such as iron, zinc, aluminum flammable by chemical reaction with bromates, chlorates, iodates, peroxides, lithium, silver nitrate, nitric acid, potassium permanganate, chromium trioxide, chlorine trifluoride, chlorine oxide, bromine trifluoride, bromine pentafluoride, bromine azide use foam, carbon dioxide, or dry chemical for firefighting purposes..
