Metal powders, incompatibilities with

BICHROMATE of SODA (10588-01-9) A strong oxidizer. Reacts violently with reducing agents, acids, acetic anhydride, hydrazine, combustible materials, organic substances, metal powders. Reacts with acrolein, antimony trisulfide, antimony tritelluride, arsenic pentasul-fide, 1,1-dichloro-l-nitroethane, 1,3-dichloropropene, diethylamine, fluorine, hydrazine, potassium iodide, sodium tetraborate, sodium tetraborate decahydrate, sodium borohydride, zirconium dusts, i-trioxane. Incompatible with ra-bis(trichlormethyl)benzene, hydroxy-lamine. Aqueous solution is caustic incompatible with acids, alcohols, aldehydes, alkylene oxides, cresols, caprolactam solution, epichlorohydrin, organic anhydrides, glycols, maleic anhydride, phenols. Attacks aluminum copper, brass, bronze, tin, zinc, especially in the presence of moisture. 

OXICLORURO de FOSFORO (10025-87-3) Fumes in moist air. Contact with water, steam, or alcohols produces hydrochloric acid, phosphoric acid, and phosphine gas, which is pyrophoric, with possible ignition or explosion (may be a delayed reaction). Contact with air produces corrosive fumes. Violent reaction with carbon disulfide, 2,6-dimethylpyiidine-M-oxide, dimethyl sulfoxide, ferrocene-l,l -dicarboxylie acid, pyridine, zinc powder. Reacts, possibly -violently, with acids, alkali metals, alkalis, combustible materials, dimethyl formamide, organic matter, zinc powder. Incompatible with acetic anhydride, iV,A -dimethyl formamide, 2,5-dimethylpyrrole, sodium. Rapid corrosion of steel and most metals, except lead, occurs in the presence of moisture. 

EXPLOSION and FIRE CONCERNS metal is a combustible solid dry powder undergoes spontaneous ignition in air eontact of metallic dust with strong oxidizers may cause fires and explosion metal is incompatible with bromine trifluoride, fluorine, and lead chromate tantalum pentoxide is incompatible with bromine trifluoride, chlorine trifluoride, and lithium minimum explosion dust concentration is less than 200 g/cm (0.2 g/L) use dry sand, dry dolomite, and dry graphite for firefighting purposes. 

A mixture of the 3 compounds exploded violently during mixing. Previously the mixture had been accidentally ignited by a spark. Aluminium powder is incompatible with oxidants, and its mixture with titanium dioxide is a thermite-like combination. See Aluminium Metal oxides See also THERMITE REACTIONS... 

Note Polar solvent soluble in alcohols, ether, benzene, and most oils usually stabilized with methanol to prevent phosgene formation flammable and highly toxic by inhalation, ingestion, or skin absorption narcotic carcinogenic incompatible with caustics, active metals, aluminum powder, potassium, sodium, magnesium. Synonyms trichloromethane, methane trichloride. 

SAFETY PROFILE Poison by intravenous route. Lanthanum and other lanthanoids can cause delayed blood clotting leading to hemorrhages. Has caused liver injury" in experimental animals. The dust is a dangerous fire hazard when exposed to flame can react vigorously with oxidizing materials. Violent reaction with nitric acid, phosphoms (above 400°C), air, halogens. Moderately explosive in the form of dust when exposed to flame or by chemical reaction. Incompatible with H2O, C, N, B, Se, Si, S. See also RARE EARTHS and POWDERED METALS. 

Uethadone Hydrochloride, USP, Methadone hydrochloride. 6-(Dimethylamino)-4.4-diphenyl-3-heptanone hy-dnK hloride (Dolophine Hydrochloride), occurs as a bitter, white crystalline powder. It is soluble in water, freely soluble in alcohol and chloroform, and insoluble in ether. Methadone IS synthesized in several ways. The method of Easton et al. is noteworthy, in that it avoids the formation of the troublesome i.someric intermediate aminonitriles. The analgesic effect and other morphine-iike properties are exhibited chiefly by the (-) form. Aqueous solutions are stable and may be sterilized by heat for intramuscular and intrave-noas use. Like all amine salts, it is incompatible with alkali and salts of heavy metals. It is. somewhat irritating when injected subcutaneously.
