As2O3
formula, see observation
1327-53-3
CAS number
DEF

A chemical product in the form of a white, odourless, tasteless powder which is slightly soluble in water, is soluble in acids, alkalies and glycenol, is derived by smelting of copper and lead concentrates and is used in pigments, ceramic enamels, aniline colours, as a decolourizing agent in glass, as an insecticide, rodenticide, herbicide and preservative.

OBS

Condensation gives product of varying purity called crude arsenic (90-95% pure). A higher-purity oxide called white arsenic is obtained by resubliming the crude As2O3 (99+%pure).

OBS

arsenic trioxide: obsolete form.

CONT

Anhydride arsénieux [...]. C'est le plus important des composés de l'arsenic; on le désigne communément, à tort, sous le nom d'«arsenic blanc», ou même d'«arsenic». Il se présente habituellement sous l'aspect d'une poudre blanche, inodore, qui se sublime au rouge sombre, peu soluble dans l'eau. Il en existe trois variétés, dont deux cristallisées [...]

OBS

Ce produit entre dans la composition des arsenicaux, des colorants, de la céramique, des insecticides, de la mort-aux-rats, du mordant, des substances thérapeutiques.

OBS

Bien que «mort-aux-rats» soit utilisé comme synonyme d'«anhydride arsénieux», ce terme désigne, en général, tout raticide.
