Hydrogen cyanide - Wikipedia
WEBHydrogen cyanide (once known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N. It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).
Prussic Acid Poisoning | Oklahoma State University
WEBSummary. It was discovered in the early 1900s that under certain conditions, sorghum is capable of releasing hydrocyanic acid (HCN or prussic acid), which makes them potentially dangerous for grazing. In the plant, HCN is attached to a larger molecule, a cyanogenic glucoside called dhurrin.
Hydrogen cyanide | Description, Uses, Effects, & Facts
WEBApr 27, 2024 · Hydrogen cyanide, a highly volatile, colorless, and extremely poisonous liquid. A solution of hydrogen cyanide in water is called hydrocyanic acid, or prussic acid. It was discovered in 1782 by a Swedish chemist, Carl Wilhelm Scheele, who prepared it from the pigment Prussian blue.
Prussic Acid Poisoning - SDSU Extension
WEBNov 18, 2021 · What is Prussic Acid and How Does Poisoning Occur? Prussic acid, also known as hydrocyanic acid or cyanide, is a rapidly acting, lethal toxin. Prussic acid inhibits oxygen utilization by the animal at the cellular level resulting in suffocation. Ruminants are more susceptible because the rumen microbes have enzymes that release the …
Prussic acid toxicity explained as recent drought ramps up risk
WEBJun 27, 2022 · Clinical signs of prussic acid toxicity are: Muscle tremors; Increased respiration rate; Excess salivation; Staggering; Convulsions; Collapse; Producers should note prussic acid levels are highest in the leaves of young plants, and the upper leaves contain the most toxin.
Cyanide poisoning - Wikipedia
WEBCyanide poisoning can result from the ingestion of cyanide salts; imbibing pure liquid prussic acid; skin absorption of prussic acid; intravenous infusion of nitroprusside for hypertensive crisis; or the inhalation of hydrogen cyanide gas. The last typically occurs through one of three mechanisms:

WEBAqueous solutions are referred to as hydrocyanic acid and prussic acid. Persons whose clothing or skin is contaminated with cyanide-containing solutions can secondarily contaminate response personnel by direct contact or through off-gassing vapor. Hydrogen cyanide is a colorless or pale-blue liquid at room temperature.
