Incompatible acids

DEHYDROACETIC ACID Incompatible with cationics and some nonionics... 

STEARONE. An aliphatic ketone, insoluble in water, stable to high temperatures, acids, and alkalies compatible with high-melting vegetable waxes, paraffins, and fatty acids incompatible with resins, polymers and organic solvents at room temperature but compatible with them at high temperature. 

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. 

Combustible when exposed to heat or flame can react with oxidizing materials. To fight fire, use water, CO2, dry chemical. Potentially explosive reaction with concentrated nitric acid. Incompatible with acetanilide, alkalies, ferric salts, spirit nitrous ether, urethan. When heated to decomposition it emits acrid smoke and irritating fumes. 

Violent reaction with benzoyl chloride combined with KOH, Bt2, barium carbonate, CS2, Cr(OCl)2, Cu, Pb, HNO3, BaCOs, H2SO4, hot water, (CH3)2S04, dibromomalononitrile, sulfuric acid. Incompatible with acids, ammonium chloride + trichloroacetonitrile, phosgene, cyanuric chloride, 2,5-dinitro-3-methylbenzoic acid + oleum, trifiuroroacryloyl chloride. Reacts with heavy metals (e.g., brass, copper, lead) to form dangerously explosive heavy metal azides, a particular problem in laboratory equipment and drain traps. When heated to decomposition it emits very toxic fumes of NOx and Na20. See also AZIDES. 

DOT CLASSIFICATION Forbidden SAFETY PROFILE Mercury compounds are poisons. An explosive sensitive to friction, impact, heating, or contact with sulfuric acid. Incompatible with sulfuric acid. When heated to decomposition it emits very toxic fumes of Hg and NO. See also MERCURY COMPOUNDS and NITRIDES. 

Properties Monoclinic green crystals. Loses 3H20 at 100C, decomposes at 230C. Soluble in water and acetic acid incompatible with alkali and ammonia, since these react to precipitate ferric hydroxide. 

ACETIC ACID, COBALT(II) SALT (71-48-7) Co(CjH30j)i 4HOH Noncombustible solid. Solution in water is basic (pH 6.8 to >7.0) reacts with acids. Some cobalt compounds react with oxidizers, acetylene. Cobalt is a known animal carcinogen. ACETIC ACID, CUPRIC SALT (142-71-2) Cu(C2H302)i H20 Noncombustible solid. Solution in water is basic reacts with acids. Incompatible with acetylides, hydrazine, nitromethane, mercurous chloride nitrates, sodium hypobromite. Thermal decomposition releases fumes of copper, acetic acid, and carbon oxides. 

ACETIC ACID, LEAD(II) SALT TRIHYDRATE (6080-56-4) Pb(C2H302)2 3H20 Contact with acids forms acetic acid. Incompatible with oxidizers, bases, acetic acid alkalis, aUcylene oxides, ammonia, amines, bromates, carbonates, citrates, chlorides, chloral hydrate cresols, epichlorohydrin, hydrozoic acid, isocyanates, methyl isocyanoacetate, phenols, phosphates, salicylic acid sodium salicylate, sodium peroxyborate, potassium bromate resorcinol, salicylic acid, strong oxidizers, sulfates, sulfites, taimin, tartrates, tinctures trinitrobenzoic acid, urea nitrate. On small fires, use dry chemical, Halori, or CO2 extinguishers. 

ACETYL PROPANE (563-80-4) CjHioO Highly flammable liquid. Forms explosive mixture with air [explosion limits in air (vol %) 1.2 to 8.0 flash point 26°F/-3°C 43°F/6°Cl autoignition temp 887°F/475°C]. Reacts violently with strong oxidizers, aldehydes, nitric acid, perchloric acid. Incompatible with acids, anhydrides,... 

BIS (4-HYDROXYFENYL) PROPANE (80-05-7) C,sH,60j Combustible solid. Dust forms explosive mixture with air (flash point 207°F/97°C autoignition temp 510°F/266°C Fire Rating 1). Dust or powder forms explosive mixture with air. Violent reaction with strong oxidizers concentrated nitric acid. Incompatible with strong bases, amines, amides, and inorganic hydroxides acid chlorides and acid anhydrides. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or COj extinguishers. 

BORIC ACID (10043-35-3) BH3O3 Aqueous boric acid is a weak acid incompatible with alkali carbonates hydroxides strong reducing agents, including metal hydrides, nitrides, sulfides, and alkali metals. Violent reaction with potassium metal. Contact with acetic anhydride forms a heat-sensitive explosive. On small fires, use water fog.
