A cyanide is any chemical compound that contains the cyano group C≡N, with the carbon atom triple-bonded to the nitrogen atom. Inorganic cyanides contain the highly toxic cyanide ion CN-, and are the salts of the acid hydrogen cyanide (HCN). Organic cyanides contain the cyano group single-bonded to another carbon atom, and are also known as nitriles. The cyano group is also known as the nitrile group. Cyanide - Appearance and odour.

Cyanide - Absorption. The most usual route of absorption is by inhalation of hydrogen cyanide gas, which can be formed from alkaline cyanides and certain complex cyanides by the action of acid. Hydrogen cyanide poisoning is also common as a result of smoke inhalation after house fires. Ingestion is equally dangerous, although this route of absorption is usually deliberate (suicidal or criminal). Absorption through the skin is also possible, though rare. Cya ...

The cyanide ion, if used as poison, is generally delivered in the form of gaseous hydrogen cyanide or in the form of potassium cyanide (KCN) or sodium cyanide (NaCN). Zyklon B, the poison gas used in Nazi gas chambers during the Holocaust, works by delivering hydrogen cyanide gas. Cyanide is also the compound used in U.S. gas chambers for execution. Cyanides were stockpiled in both the Soviet and the United States chemical weapons arsenals in the 1950s and 1960s. During the Cold War, the Soviet Union was thought to be planning ...

Cyanides can be produced by certain bacteria, fungi, and algae, and are found in a number of foods and plants. In plants, cyanides are usually bound to sugar molecules in the form of cyanogenic glycosides and serve the plant as defense against herbivores. Cassava roots (aka manioc), an important potato-like food grown in tropical countries, contain cyanogenic glycosides and must be processed prior to consumption (usually by extended boiling). Fruits that have a pit, such as cherries and apricots, often contain either cyanides or cyanogenic g ...

A blood agent or cyanogen agent is a chemical compound, containing the cyanide group, that prevents the body from utilizing oxygen. The term "blood agent" is a misnomer, however, because these agents do not actually affect the blood in any way. Rather, they exert their toxic effect at the cellular level, by interrupting the electron transport chain in the inner membranes of mitochondria (see cyanide). The mechanism of action is nearly identical to that of carbon monoxide. Examples of blood agen ...

Zyklon B (IPA tsykloːn ˈbeː) was the tradename of a cyanide-based insecticide notorious for its use by Nazi Germany during the Holocaust to kill millions of people. It is also refered to as Cyclon B. It consisted of hydrocyanic acid (prussic acid), a stabilizer, and a warning odorant that were impregnated onto various substrates, typically small absorbant pellets, fiber discs, or diatomaceous earth. It was stored in airtight containers; when exposed to air, the substrates evolved gaseous hydrogen cyanide (HCN). Zyklon B is still in production in Czech Republic in Kolín under the tradename Uraga ...

The Tylenol murders occurred in the autumn of 1982, when seven people in the Chicago, Illinois area in the United States died after ingesting Extra Strength Tylenol medicine capsules which had been laced with cyanide poison. This incident was the first known case of death caused by deliberate product tampering. The perpetrator has never been caught, but the incident led to reforms in the packaging of over-the-counter substance and federal anti-tampering laws. 1982 Chicago Tylenol murders - The incidents.

The term vitamin B12 (or B12 for short) is used in two different ways. In a broader sense it refers to a group of Co-containing compounds known as cobalamins - cyanocobalamin (an artefact formed as a result of the use of cyanide in the purification procedures), hydroxocobalamin and the two coenzyme forms of B12, methylcobalamin (MeB12) and 5-deoxyadenosylcobalamin (adenosylcobalamin - AdoB12Including:

Cyanogen is a chemical compound (CN)2. The CN entity behaves like a halogen. As do halogens, it forms molecules consisting of two CN groups, N≡C-C≡N. Compounds containing the CN group are called cyanides, cyanates, and thiocyanates. "Cyanogen" refers to a single CN group in some molecules, such as cyanogen chloride (NCCl). Cyanogen at room temperature is a colourless gas with a pungent odour. Its melting point is -27.9°C (-18.2°F) whilst its boiling point is -20.1°C (-4.2°F). Its density is approximately twic ...

Potassium cyanide plays an important role in the Swedish classic novel Doctor Glas by Hjalmar Söderberg. It is also commonly used in the detective stories of Agatha Christie, for instance And Then There Were None; one of her novels, Sparkling Cyanide, was named for it. Although it was used incorrectly, it was also used to kill Yuka Nakagawa in Battle Royale. It is unconfirmed whether or not it was truly KCN that ki ...

As all cyanides, potassium cyanide is a potent poison blocking the cells' electron transport chain by forming a permanent bind with the iron atom in heme of cytochromes. The result is disruption of the cell's respiration. The effects of potassium cyanide are similar to sodium cyanide. Once more than 100–200 mg of potassium cyanide is consumed, consciousness is lost within one minute, sometimes within 10 seconds, depending on the strength of the body's immunity and the amount of food present in the stomach. After a span of about 45 m ...

Gold cyanidation - The Effect of pH. It is critical to avoid the release (volatilization) of cyanide as toxic hydrogen cyanide gas as free hydrogen cyanide gas is highly toxic; hydrogen cyanide boils at 26 °C, barely above room temperature. Cyanide ions may become hydrogen cyanide gas when they acquire free protons. CN- + H+ = HCN(g) Therefore the free proton concentration is kept low by the addition of alkali such as Lime (calcium hydroxide) or sodium hydroxide to ensure th ...

The use of cyanide as a fishing technique was first documented in the Philippines in 1962[1]. More than 150,000 kg of cyanide is believed to be used in the Philippines annually by the aquarium trade and more than a million kg have been used since the 1960’s[2][3]. The use of cyani ...
