화학적 성질

Cyanides comprise a wide range of compounds, all of which have a CN molecule and exist in either a solid, liquid, or gaseous form. Physical characteristics range froma colorless or pale blue liquid with a faint bitter almond-like odor (hydrogen cyanide, HCN) to a white solid, powder, or crystalline hygroscopic salt (sodium cyanide, NaCN) to a colorless toxic gas also with an almond-like odor (cyanogens, NCCN). Cyanide compounds are either organic or inorganic. Organic cyanides contain a noncovalent CN functional group and are typically called the cyano group or nitriles. A common nitrile is methyl cyanide, also known as acetonitrile (CH3CN). Inorganic cyanides have a negatively charged polyatomic cyanide ion (CN) and are generally referred to as cyanides. This group includes the cyanide salts (i.e., sodium cyanide, NaCN) which are considered the most toxic form. KCN and NaCN are white crystalline solids with a faint almond odor. Sodium cyanide also has a slight odor of hydrocyanic acid when damp. KCN: boiling point=1625℃ ; freezing/melting point=634℃ . NaCN: boiling point 1496℃; freezing/melting point=564℃ . NFPA 704 M Hazard identification (KCN and NaCN): Health 3, flammability 0 , reactivity 1. Soluble in water; slow decomposition releases highly toxic and flammable hydrogen cyanide gas.

안전 및 규제

규제 정보	Regulation (EC) No 178/2002 (amended)Cyanide: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces.

화재 위험	Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]:Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. UN1802, UN2032, UN3084, UN3093, UN1796 (above 50%), UN1826 (above 50%), and UN2031 (above 65%) may act as oxidizers. Also consult ERG Guide 140. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance may react with water (some violently), releasing corrosive and/or toxic gases and runoff. Corrosives in contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2024)
건강 유해성	Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]:TOXIC and/or CORROSIVEinhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air may release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental contamination. (ERG, 2024)
유해성 요약	Cyanide is used in a number of industries and is found at low levels in air from car exhaust. Cyanide is extremely toxic to humans. Chronic (long-term) inhalation exposure of humans to cyanide results primarily in effects on the central nervous system (CNS). Other effects in humans include cardiovascular and respiratory effects, an enlarged thyroid gland, and irritation to the eyes and skin. No data are available on the carcinogenic effects of cyanide in humans via inhalation. Animal studies have suggested that oral exposure to cassava (a cyanide-containing vegetable) may be associated with malformations in the fetus and low fetal body weights. EPA has classified cyanide as a Group D, not classifiable as to human carcinogenicity.

용도

Cyanide, standard solution is used to dissolve metals and their ores. It is also used in clinical chemistry and in waste water treatment facilities to determine the concentration of dissolved and particulate materials.
