3. Use and Manufacturing
4.1 Definition
ammonium thiocyanate: A colourless, soluble crystalline compound,NH4NCS. It is made by theaction of hydrogen cyanide on ammoniumsulphide or from ammoniaand carbon disulphide in ethanol. Onheating, it turns into its isomerthiourea, SC(NH2)2. Its solutions givea characteristic blood-red colour withiron(III) compounds and so are employedas a test for ferric iron. Ammoniumthiocyanate is used as arapid fixative in photography and asan ingredient in making explosives.
4.2 General Description
Ammonium thiocyanate is a colorless crystalline solid. Ammonium thiocyanate is soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium thiocyanate is used in chemical analysis, in photography, as a fertilizer, and for many other uses.
4.3 Potential Exposure
It has many uses in making matches,fabric processing; metals processing; chemical manufacturing,electroplating; zinc coating; liquid rocket propellents,fabric dyeing, polymerization catalyst, in photography.Used as a laboratory chemical. May be used as an agriculturalchemical: herbicides, weed killers, defoliants.
4.4 Produe Method
Ammonium thiocyanate (plus ammonium sulfide) [CAS: 12135-76-1] may be made by reaction of ammonia and carbon disulfide, a reaction which probably accounts for the presence of ammonium thiocyanate in the products of the destructive distillation of coal. This reaction corresponds to the formation of ammonium cyanate from ammonia and carbon dioxide.
4.5 Purification Methods
Crystallise it three times from dilute HClO4 to give material optically transparent at wavelengths longer than 270nm. It has also been crystallised from absolute MeOH or from acetonitrile.

5.2 Fire Hazard
Special Hazards of Combustion Products: Decomposes to form ammonia, hydrogen sulfide, and hydrogen cyanide. Oxides of nitrogen may also form. All of these products are toxic.
5.3 Other Preventative Measures
If material not on fire and not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Personnel protection: Keep upwind. ... Avoid breathing vapors. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
5.4 Cleanup Methods
A waste solution containing ammonium thiocyanate from a coke oven is sprayed into a combustion furnace and converted to gypsum by air oxidation.
Environmental considerations: Water spill: Neutralize with dilute acid or removable strong acid. Add calcium hypochlorite. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Environmental considerations: Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be contained with a flexible impermeable membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Remove slowly into a large container of water. Add soda ash slightly by stirring. After 24 hr, decant or siphon into another container. Neutralize with 6M-HCl.
5.5 DisposalMethods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material=s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
5.6 RIDADR

5.6 Fire Fighting Procedures
Extinguish with water.
If material on fire or involved in fire: Extingiush fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
/During fire fighting/ wear goggles and self-contained breathing apparatus.

7.16 Air & Water Reactions
Water soluble.
7.17 Reactivity Profile
Ammonium thiocyanate can release ammonia vapors if mixed with a chemical base or with an acid. Violent or explosive reactions have occurred when thiocyanates are mixed with oxidizing agents (such as chlorates(potassium chlorate), nitrates, nitric acid, and peroxides). Nitric acid violently oxidized a thiocyanate solution [Bretherick 1979 p. 121]. An explosion of guanidine nitrate demolished an autoclave built to withstand 50 atmospheres, in which Ammonium thiocyanate was being made from Ammonium thiocyanate and lead nitrate [C. Angew.

7.18 Health Hazard
Inhalation of dust causes irritation of nose and throat. Ingestion causes dizziness, cramps, nervous disturbances. Dust irritates eyes. Can be absorbed through skin; prolonged contact may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system.
7.19 Fire Hazard
Special Hazards of Combustion Products: Decomposes to form ammonia, hydrogen sulfide, and hydrogen cyanide. Oxides of nitrogen may also form. All of these products are toxic.

Used as a laboratory chemical. May be used as an agricultural chemical: herbicides, weed killers, defoliants.
7.22 First aid
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
