[är′sēn] (inorganic chemistry) H₃ As A colorless, highly poisonous gas with an unpleasant odor.

Arsine

AsH₃, a colorless, odorless gas (impurities usually produce an odor of garlic). Boiling point, —62.4°C; melting point, -113.5°C. Discovered in 1775 by K. W. Scheele. Pure arsine is produced by the action of water on sodium arsenide, Na₃As. The reduction of acid-soluble arsenic compounds by hydrogen results in the formation of a mixture of arsine and hydrogen at the moment of liberation—for example:

As₂O₃ + 6Zn + 6H₂SO₄ = 2AsH₃ + 6ZnSO₄ + 3H₂O

If the mixture is passed through a glass tube heated to 400°-500°C, the arsine will decompose into hydrogen and arsenic, which forms a black film with a vitreous luster along the cool sections of the tube. The test is used to determine the presence of arsenic in various substances; it was developed in 1836 by the English chemist J. Marsh (1794–1846).

Arsine is one of the most poisonous commercial toxins known. It generally induces acute poisoning. It has a primarily hemolytic effect. The latent period lasts two to eight hours, toward the end of which headache, dizziness, rigor, vomiting, and abdominal pain occur. The skin takes on a sunburned appearance, and body temperature initially rises to 38°-39°C. The patient may go into a coma after a certain period of time. Preventive measures against arsine poisoning include the use of arsenic-free metals and acids, the mechanization of production processes, the sealing of industrial equipment, and the creation of an effective ventilation system.

arsine

[ahr´sēn] any of several colorless, volatile arsenical bases that are highly toxic and carcinogenic; the most common one is AsH₃, arsenous hydride. Some of their compounds have been used in warfare, and a major industrial use is in the production of microelectronic components. Inhalation leads to massive red blood cell hemolysis with secondary renal failure and jaundice. A garliclike odor may be noted with high concentrations.

ar·sine

(ar'sēn), A cell and blood poison, many organic derivatives of which have been used in chemical warfare. Synonym(s): arsenic trihydride, arseniureted hydrogen, arsenous hydride
