Copper, incompatibilities with

Strong oxidizers and strong acids are incompatible with nikanolamines. Reactions, generating temperature and/or pressure increases, may occur with halogenated organic compounds. Alkan olamines are corrosive to copper and brass and may react. Contact with aluminum by alkan olamines, particularly when wet or at elevated temperatures (60°C), should be avoided. 

Finally, anions that are incompatible with oxidants will give rise to violent reactions with iodates. This goes for cyanides, thiocyanates and sulphides. In the last case, arsenic, antimony, copper and tin sulphides were the main ones cited. 

Arsine is incompatible with strong oxidizers and various metals including aluminum, copper, brass, and nickel. It may be decompose on exposure to light to produce hydrogen gas and arsenic metal. 

Despite the good performance characteristics of HMTD, it had several significant faults. As mentioned earlier, the peroxide bond is very reactive. This made HMTD incompatible with most metals. It actively attacked aluminum, tin, zinc, brass, copper, iron, and lead. HMTD was also very unstable when stored, exhibiting tremendous weight loss over short periods of time. In the end, it was judged both too reactive and too thermally unstable for any practical usage. It fell into obscurity in the explosives community in the early 1950s. 

Stability. Incompatible with metals such as aluminium and copper, halogenated organics, strong acids, oxidizing materials and absorbent materials (cellulose, sawdust) (Dow Chemical Company, 1999a)... 

Alpha tocopherol Beta, delta, and gamma are considered to be more effective antioxidants Incompatible with peroxides and metal ions, especially iron, and copper. May be absorbed into plastic. Protect from light, and oxygen during storage... 

Note Copper columns often cause adsorption problems incompatible with amines, anilines, acetylenes, terpenes, steroids, and strong bases. 

Austenitic SS s are also used in freshwater. However, because of cost their use is limited mainly to applications in which copper-zinc alloys are unsuitable, as in tubes in which the process side is incompatible with copper base alloys. To avoid pitting, type 304 (UNS S30400) SS is normally limited to services in which the chloride ion concentration is at a maximum of 100 ppm, and type 316 SS is limited to services in which the chloride ion is a maximum of 500 ppm. The relative pitting and crevice corrosion resistance of SS alloys can be approximated by the following equation ... 

ACGIH TLV TWA 1 mg(Cu)/m3 DOT CLASSIFICATION 6.1 Label Poison, KEEP AWAY FROM FOOD SAFETY PROFILE Poison by intraperitoneal route. See also CYANIDE and COPPER COMPOUNDS. Incompatible with magnesium. When heated to decomposition it emits toxic fiimes of NOx and CNT... 

To fight fire, use alcohol foam, CO2, dr) chemical. Violent polymerization occurs on contact with ammonia, alkali hydroxides, amines, metallic potassium, acids, covalent halides (e.g., aluminum chloride, iron(III) chloride, tin(IV) chloride, aluminum oxide, iron oxide, rust). Explosive reaction with glycerol at 200°. Rapid compression of the vapor with air causes explosions. Incompatible with bases, alcohols, air, m-nitroaniline, trimethyl amine, copper, iron chlorides, iron oxides, magnesium perchlorate, mercaptans, potassium, tin chlorides, contaminants, alkane thiols, bromoethane. When heated to... 

DOT CLASSIFICATION Forbidden (dry) SAFETY PROFILE A deadly poison. An explosive sensitive to shock or heating to 250°C. Will explode spontaneously during ciy staUization. Mixtures with calcium stearate may explode spontaneously. May explode spontaneously after prolonged contact with copper, zinc, or their aUoys (e.g., brass). Incompatible with CS2. Used in commercial blasting caps and military ammunition. When heated it emits highly toxic fumes of Pb and NOx. See also LEAD COMPOUNDS, AZIDES, and EXPLOSIVES, HIGH. 

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.
