구리 아아세토아르센산 화학적 특성, 용도, 생산

• 화학적 성질

  Paris green (copper acetoarsenite) is an odorless emerald green crystalline powder which decomposes upon heating.

• 용도

  Insecticide; wood preservative; as pigment, particularly for ships and submarines.

• 제조 방법

  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.

• 정의

  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.

• 일반 설명

  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.

• 공기와 물의 반응

  Insoluble in water. Decomposes on prolonged heating in water [Merck].

• 반응 프로필

  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.

• 위험도

  Toxic by ingestion.

• 건강위험

  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.

• 화재위험

  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.

• Safety Profile

  Poison by ingestion and possibly other routes. An insecticide. When heated to decomposition it emits very toxic fumes of As. See also ARSENIC

• 잠재적 노출

  This material, and organoarsenic compound, is used primarily as an insecticide; it may be used as a wood preservative and a pigment, particularly for ships and submarines; and also finds use as an anthelmintic.

• 운송 방법

• 비 호환성

  Can react vigorously with oxidizers. Emits highly toxic arsenic fumes on contact with acid or acid fumes; and in elevated temperatures.

• 폐기물 처리

  Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
