化学的特性
Paris green (copper acetoarsenite) is an
odorless emerald green crystalline powder which decomposes
upon heating.
使用
Insecticide; wood preservative; as pigment, particularly for ships and submarines.
製造方法
Copper(II) acetoarsenite, Cu(C2H3O2)2·3Cu(AsO2)2, is a water-insoluble emerald green, poisonous powder. It is also known as paris green. Copper(II) acetoarsenite is produced by the reaction of a solution of copper(II) sulfate with arsenic(III) oxide, sodium carbonate, and acetic acid. It can also be prepared by reaction of copper(II) oxide with a hot solution of acetic acid and arsenic(III) oxide or by reaction of copper(II) acetate with arsenic(III) oxide. It has limited application as an antifouling pigment, in the preservation of wood, and as an insecticide.
定義
Emerald: The green gem variety ofberyl: one of the most highly prizedgemstones. The finest specimensoccur in the Muzo mines, Colombia.Other occurrences include the UralMountains, the Transvaal in SouthAfrica, and Kaligunan in India. Emeraldscan also be successfully synthesized.
一般的な説明
An emerald-green powder. Usually contains some water. Insoluble in water. Toxic by inhalation and by ingestion. Used as a wood preservative, insecticide, and pigment.
空気と水の反応
Insoluble in water. Decomposes on prolonged heating in water [Merck].
反応プロフィール
Copper acetoarsenite is soluble in acids. Is unstable in acids, bases and toward hydrogen sulfide [Merck]. Has weak oxidizing or reducing powers. Redox reactions can however still occur.
危険性
Toxic by ingestion.
健康ハザード
Copper acetoarsenite is extremely toxic; the probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 150-lb. person. Some absorption may occur through the skin and by inhalation, but most poisonings result from ingestion. It may cause eye and respiratory tract irritation. Industrial exposure may cause dermatitis.
火災危険
Poisonous, volatile arsenic oxide may be formed in fires. Exposure of dust to flame may cause explosion. When heated, or on contact with acid or acid fumes, Copper acetoarsenite emits highly toxic fumes. Decomposes readily in the presence of water and carbon dioxide to yield phytotoxic arsenical compounds. Can react vigorously with oxidizing materials. Unstable in acids and bases. Hazardous polymerization may not occur.
安全性プロファイル
Poison by ingestion and
possibly other routes. An insecticide. When
heated to decomposition it emits very toxic
fumes of As. See also ARSENIC
職業ばく露
