Iodine, incompatibilities with

It will be appreciated that iodate is incompatible with both iodide (cf. Section IV.21, reaction 6) and with thiocyanate (Section IV.21, reaction 9) since iodine is liberated in acid solution. Also sulphide is incompatible with both bromate and iodate (oxidation to sulphate occurs), and an arsenite is oxidized by iodate in acid solution. These facts should therefore be borne in mind when interpreting Table V.30. An independent test for iodate (test 11) is provided below this can be performed before the silver nitrate tests. 

DOT CLASSIFICATION Forbidden SAFETY PROFILE A very shock- and friction-sensitive explosive. Incompatible with sulfur-containing alkenes. When heated to decomposition it emits very toxic fumes of r and NOx. See also IODINE. 

Incandescent reaction with fluorine. Reacts to form pyrophoric or explosive products with bromine trifluoride, trifluoromethyl hypofluorite. Mixtures with formamide + iodine + sulfur trioxide are storage hazards, releasing carbon dioxide and sulfuric acid. Incompatible with oxidizing materials. 

Readily absorbed through the skin. Human systemic effects by ingestion convulsions, dyspnea, gastrointestinal effects. A severe skin and eye irritant. Incompatible with alkalies, NH3, antipyrine, phenol, iron and lead salts, iodine, KMn04. When heated to decomposition it emits acrid smoke and irritating fumes. Used as a topical antibacterial agent, as an intermediate, hair dye component, and analytical reagent. 

SAFETY PROFILE Experimental poison by subcutaneous route. Moderately toxic to humans by ingestion. Moderately toxic experimentally by ingestion, intraperitoneal, and intravenous routes. An experimental teratogen. Human systemic effects by multiple and unspecified routes toxic psychosis, excitement, respiratory stimulation, nausea or vomiting, and sweating. Experimental reproductive effects. Mutation data reported. A powerful irritant which affects the central nervous system. Incompatible with ferric salts, mineral acids, iodine, lead acetate, silver nitrate, sodium phosphate powder. When heated to decomposition it emits toxic fumes of Na20. 

Incompatible with soaps, anionic surfactants, high concentrations of nonionic surfactants, bentonite, iodine, phenylmercuric nitrate, alkali hydroxides, and acid dyes. Aqueous solutions react with metals. 

Incompatible with aluminum, calcium, heavy metals, iodine solutions, perchloric acid, and oxidizing agents. Oleic acid reacts with alkalis to form soaps. 

Thymol is incompatible with iodine, alkalis, and oxidizing agents. It liquefies, or forms soft masses, on trituration with acetanilide, antipyrine, camphor, monobromated camphor, chloral hydrate, menthol, phenol, or quinine sulfate. 

COPPER (7440-50-8) Cu The powder forms the friction-, heat-, or shock-sensitive explosive detonator, copper acetylide, with acetylene gas acetylenic compounds and ethylene oxides. The powder forms explosive materials with azides (e.g., sodium azide forms potentially explosive copper azide). Finely divided material forms friction-, heat-, or shock-sensitive explosive with powdered divided bromates, chlorates, and iodates of barimn, calcimn, magnesium, potassium, sodium, or zinc. Violent reaction, possibly explosive, when finely dispersed powder comes in contact with strong oxidizers ammonium nitrate alkynes, bromine vapor, calcium carbide, chlorine, ethylene oxide, hydrazine mononitrate, hydrogen peroxide, hydrogen sulfide, finely divided bromates, iodine, lead azide, potassium peroxide, sodium peroxide (incandescence), sulfuric acid. Incompatible with acids, anhydrous ammonia chemically active metals such as potassium, sodium, magnesium, and zinc, zirconium, strong bases. 

LEAD SULFIDE (1314-87-0) PbS Noncombustible solid. Reacts violentiy with iodine monochloride, hydrogen peroxide. Incompatible with bromates, chlorates, hydrazinium nitrate, iodates, mercurous chloride, silver azide, zinc(II) nitrate, hexahydrate. 

HgjCU Noncombustible solid. Violent reaction with sodium. Slow decomposition in light, forming mercury and mercuric chloride. Incompatible with acetylene, alkali chlorides, ammonia, bromides, azides, carbonates, chlorine dioxide, cocaine hydrochloride, cyanides, copper and copper salts, hydrogen peroxide, hydroxides, iodides, iodine, iodoform, lead salts, lithium, potassium iodide, mbidium, silver salts, sodium carbide, sulfates, sulfides, sulfites. On small fires, use any kind of extinguishers.
