Cyanide sulfur

Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. It has a coefficient of expansion almost equal to that of soda-lime-silica glass, and is therefore used to make sealed electrodes in glass systems. The metal does not oxidize in air at any temperature, but is corroded by halogens, cyanides, sulfur, and caustic alkalis.

In the double displacement reaction above, dissolved sodium cyanide (NaCN) and sulfuric acid (H2S04) react to form sodium sulfate (Na2S04) and an extremely poisonous gas called hydrogen cyanide (HCN). The (aq) means these substances are an aqueous solution. An aqueous solution is made by dissolving chemicals in water. In this reaction, the sodium cyanide, sulfuric acid, and sodium sulfate are all dissolved in water. The (g) that follows the formula for hydrogen cyanide indicates that this chemical is a gas. The hydrogen cyanide will bubble out of the solution, leaving behind the sodium sulfate that is still dissolved in the water.

Toxic chemicals tliat could potentially cause a major problem if accidentally released into tlie atmosphere include clilorine, hydrogen fluoride, hydrogen chloride, ammonia, chloropicrin, gasoline lead additives, vinyl cliloridc. and benzene. Hiis chapter addresses the process application of some chemicals from the foregoing list, as well as some others that are considered to be highly toxic hydrogen cyanide, sulfuric acid, and etliylene. Process considerations, physical and chemical properties, healtli effects, and metliods of manufacture of tliese chemicals are discussed in conjunction with potential causes of release. 

Explosive or potentiaOy explosive reaction with ammonia, cesium fluoride + fluorocarboxylic acids, cesium heptafluoropropoxide, 1- or 2-fluoriminoperfluoropropane, graphite, halocarbons (e.g., carbon tetrachloride, chloroform, perfluorocyclobutane, iodoform, 1,2-dichlorotetrafluoroethane), liquid hydrocarbons (e.g., anthracene, turpentine), hydrogen, hydrogen -I- oxygen, hydrogen fluoride + seleninyl fluoride + heat, nitric acid, silver cyanide, sulfur dioxide, carbon monoxide, sodium acetate, sodium bromate, stainless steel, water. 

Virtually all organic chemicals are made wholly or in part from petroleum and natural gas. Methane, ethane, propane, butane, ethylene, propylene, butylenes, cyclohexane, and other nonaromatic hydrocarbons and their derivatives are made entirely from petroleum and natural gas. Toluene, xylenes, cresylic acids, ammonia, cyclopentadiene, and their derivatives are made principally, although not entirely, from petroleum and natural gas. Benzene, acetylene, hydrogen cyanide, sulfur, and their derivatives are made in part from petroleum and natural gas, although other sources are more important. As a matter of fact, there are very few organic chemicals which are not made wholly or in part from petroleum or natural gas. A few examples of chemicals not made from petroleum or natural gas are naphthols, regenerated cellulose, fatty acids, toxaphene, furfural, glutamic acid, and sorbitol.
