Lithium bromide potassium alloys

EXPLOSION and FIRE CONCERNS nonflammable NFPA rating (not rated) explosive reaction with crown ethers or potassium hydroxide violent reaction with lithium, sodium-potassium alloy, acetone, or bases incompatible with metals, caustic alkali, and strong oxidants decomposition emits highly toxic gases and vapors (such as hydrogen bromide and bromine) use dry chemical, carbon dioxide, water spray, fog or foam for firefighting purposes. 

Ethers Aiuminum bromide. Aluminum chloride. Boron tribromide. Boron trichloride. Diborane. Diphenyl phosphide, lithium salt. Hydrobromic acid. Hydriodic acid. Lithium bromide. Lithium bromide-BFt etherate. Lithium diphenyl. Methylmagnesium iodide. Pyridine hydrochloride. Sodium iodide. Sodium-Potassium alloy. Triphenylphosphine dibromide. 

French) or BROMOFORMO (Spanish) (75-25-2) CHBrj Noncombustible liquid. Violent reaction with chemically active metals, acetone, calcium, strong caustics, potassium, potassium hydroxide, sodium hydroxide. Increases the explosive sensitivity of nitromethane. Incompatible with crown polyethers, sodium-potassium alloys. Forms friction- and shock-sensitive compounds with lithium. Aqueous solution is a medium-strong acid. Liquid attacks some plastics, rubber, and coatings. Corrosive to most metals in the presence of moisture. Thermal decon osition products include highly toxic carbonyl bromide and hydrogen bromide fumes. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or COj extinguishers. 

CARBON BROMIDE (558-13-4) Violent reaction with fluorine, hexylcyclohexyldilead, oxygen, potassium, potassium acetylene-1,2-dioxide, sodium azide, uranium(III) hydride. Mixtures with finely divided aluminum, lithium, magnesium, potassium-sodium alloy, titanium, zinc can form a friction- or shock-sensitive explosive material. Incompatible with decaborane. Attacks active metals. 

Alkali metals themselves also produce this reduction. The earliest system used was sodium in liquid ammonia 206,208,215), with which Kraus prepared trimethyltinsodium from hexamethylditin 206). Sodium-potassium alloy in ethylene glycol dimethyl ether also cleaves the same ditin J8). Most recently, lithium in tetrahydrofuran has been shown to cleave hexaphenyl-ditin 218,219) and hexa-n-butylditin 220). Also, hexaphenylditin may be cleaved by magnesium in tetrahydrofuran when the reaction is initiated by ethyl bromide 286). In an interesting variation, a catalytic amount of sodium in liquid ammonia causes the addition of vinylacetylene to hexaethylditin 287).
