亜ひ酸銅(II) 化学特性,用途語,生産方法
解説
亜ひ酸銅(II)，暗黄緑色固体。塩化銅 (II) と亜ヒ酸銅カリウムをエチルアルコール-水系の溶媒中で混合し沈殿物として得られる。水で分解する。 。これも亜ヒ酸銅といわれる。これを乾燥したものが K.W.シェーレの緑色顔料 (Scheele's green) として古くから知られている。水，エチルアルコールに不溶。希酸，アンモニア水に可溶。有毒で殺虫剤，防腐剤に用いられる。

化学的特性
An odorless, yellow-green powder. Low vapor pressure.
使用
As pigment, wood preservative, insecticide, fungicide, rodenticide.
一般的な説明
COPPER (II) ARSENITE is a fine, light-green powder. COPPER (II) ARSENITE is insoluble in water. COPPER (II) ARSENITE is very toxic by ingestion. COPPER (II) ARSENITE is used as an insecticide and fungicide.
空気と水の反応
Insoluble in water.
反応プロフィール
COPPER (II) ARSENITE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
健康ハザード
Dust irritates eyes. Ingestion causes gastric disturbance, tremors, muscular cramps, and nervous collapse that may cause death.
火災危険
Special Hazards of Combustion Products: Poisonous, volatile arsenic oxides may be formed in fires.
安全性プロファイル
Confirmed human
carcinogen. Poison. When heated to
decomposition it emits toxic fumes of As.

職業ばく露
Formerly used in agriculture as insecticide, rodenticide, and fungicide. Also used in pigments and animal medications. Not currently registered for use in the United States
輸送方法
UN1586 copper arsenite, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. Use dry chemical, carbon dioxide; water spray; or foam extinguishers. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors, or shows any signs of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156. The only respirators recommended for firefighting are SCBAs that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.
廃棄物の処理
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill
