| Description | 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: Boilingpoint=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 [(4) gas], Reactivity 1 [(2) gas].Soluble in water. | | Chemical Properties | 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. | | Uses | Fumigants, soil sterilizers, fertilizers, rodenticides. | | Uses | 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. | | Production Methods | Hydrogen cyanide is generally produced at point of use.
Production is covered under 40 CFR 415.420, applicability;
description of the hydrogen cyanide production subcategory. | | Definition | cyanide: 1. An inorganic salt containingthe cyanide ion CN–. Cyanidesare extremely poisonousbecause of the ability of the CN– ionto coordinate with the iron inhaemoglobin, thereby blocking theuptake of oxygen by the blood. 2. Ametal coordination complex formedwith cyanide ions. | | Definition | ChEBI: A pseudohalide anion that is the conjugate base of hydrogen cyanide. | | General Description | Aqueous solutions with a faint odor of bitter almonds. Toxic by skin absorption, by ingestion, and inhalation of the hydrogen cyanide from the decomposition of the material. Toxic oxides of nitrogen are produced in fires involving Methyl4-(cyanomethyl)benzoate. Obtain the technical name of the material from the shipping papers and contact CHEMTREC, 800-424-9300 for specific response information. | | Air & Water Reactions | Water soluble. Inorganic cyanides react slowly with water to evolve gaseous hydrogen cyanide (HCN). | | Reactivity Profile | CYANIDE SOLUTIONS slowly evolve hydrogen cyanide, a flammable and poisonous gas. Acids cause the rapid evolution of HCN. Carbon dioxide from the air is sufficiently acidic to liberate HCN from solutions of cyanides. Incompatible with isocyanates, nitrides, and peroxides. Mayinitiate polymerization reactions of epoxides. May react exothermically with metal salts to produce explosive products or evolve gaseous hydrogen. | | Hazard | Cellular asphyxiation, respiration inhibition, highly toxic; very poisonous. | | Health Hazard | TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will 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 pollution. | | Fire Hazard | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | | Safety Profile | Very poisonous by
most routes. Cyanide directly stimulates the
chemoreceptors of the carotid and aortic
bodies with a resultant hyperpnea (increase
in the depth and rate of respiration). Cardac
irregularities are often noted, but the heart
invariably outlasts the respirations. Death is
due to respiratory arrest of central origm. It
can occur withn seconds or minutes of the
inhalation of htgh concentrations of HCN
gas. Because of slower absorption, death
may be more delayed after the ingestion of
cyanide salts, but the critical events sdl
occur within the first hour. Two other
sources of cyanide have been responsible for
human poisoning: the naturally occurring
amygdalin and the drug nitroprusside.
Amygdalin is a cyanogenic glycoside found
in apricot, peach, and similar fruit pits and in
sweet almonds (Sayre and Kaymakcalan, | | Potential Exposure | Sodium and potassium cyanides are
used primarily in the extraction of ores, electroplating,
metal treatment, and various manufacturing processes.
Iodine cyanide: Used generally for destroying all lower
forms of life; in taxidermy to preserve insects, etc. | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If this chemicalhas been inhaled, remove from exposure, begin rescuebreathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit. Keep under observationfor 24-48 h as symptoms may return.Note: Use amyl nitrate capsules if symptoms develop. Allarea employees should be trained regularly in emergencymeasures for cyanide poisoning and in CPR. A cyanideantidote kit should be kept in the immediate work area andMUST be rapidly available. Kit ingredients should bereplaced every 1-2 years to ensure freshness. Personstrained in the use of this kit, oxygen use, and CPR must bequickly available.
Note to physician: Consider the administration ofKetocyanor (cobalt edetate) in dose of 300-600 mg i.v. initially. If recovery does not occur quickly (in 1-2 min) givea second dose of 300 mg, followed by i.v. glucose 5%.Alternatively, administer sodium nitrite (3%) in an i.v. doseof 10 mL over 3 min. | | Carcinogenicity | There is no evidence that exposure
to cyanide causes cancer. USEPA lists cyanide as not
classifiable with respect to its potential to cause cancer in
humans. However, certain compounds included in the cyanide
group may be human carcinogens. For example, acrylonitrile
has been judged to be a probable human carcinogen.
Details of these effects are provided in the appropriate
sections where individual compounds are discussed. | | storage | Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with cyanidesyou should be trained on its proper handling and storage. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. Protect against physical damage. Store in cool dry place. Separate from other storageand protect from acids and oxidizing materials. | | Shipping | UN1588 Cyanides, inorganic, solid, n.o.s.,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN1935 | | Incompatibilities | Soluble in water; slow decomposition
releases highly toxic and flammable hydrogen cyanide gas.
The aqueous solution of potassium and sodium cyanide are
highly corrosive, and strong bases. KCN and NaCN react
violently with acids, releasing highly flammable hydrogen
cyanide. Potassium and sodium cyanide are incompatible
with strong oxidizers (such as acids, acid salts; chlorates,
nitrates), organic anhydrides; isocyanates, alkylene oxides;
epichlorohydrin, aldehydes, alcohols, glycols, phenols, cre-
sols, caprolactum. Attacks aluminum, copper, zinc in the
presence of moisture. KCN and NaCN absorb moisture
from the air forming a corrosive syrup. | | Waste Disposal | Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal. In
accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers. Must be
disposed properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office. Add
strong alkaline hypochlorite and react for 24 hours. Then
flush to sewer with large volumes of water
