ARSENIC (III) SULFIDE Chemical Properties,Uses,Production
Chemical Properties
Orpiment, As2S3, deep orange crystals to over 1 cm in a small group
Physical properties
Yellow or orange monoclinic crystal or powder; a red allotrope modification also known; density 3.46 g/cm3; melts at 310°C; boils at 707°C; insoluble in water; soluble in liquid ammonia and alkalies.
Occurrence
Arsenic sesquisulfide occurs in nature as the mineral orpiment. It is used as a pigment; in the manufacture of infrared-transmitting glass; in semiconductors and photoconductors; in pyrotechnics; in linoleum and oil cloth; for the removal of hairs from hides; and as a reducing agent.
Uses
manufacture of glass, particularly infrared-transmitting glass; manufacture of oil cloth, linoleum; in electrical semiconductors, photoconductors; as pigment; for depilating hides; in pyrotechnics.
Preparation
Arsenic sesquioxide may be prepared by heating arsenic trioxide with hydrogen sulfide:
As2O3 + 3 H2S → As2S3 + 3 H2O
Alternatively, it may be precipitated out from a solution of arsenous acid or arsenic trioxide in dilute hydrochloric acid by passing hydrogen sulfide into the solution:
2H3AsO3 + 3H2S → As2S3 + 6H2O.
Definition
Arsenic(III) sulfide (Arsenic tri-sulfide glass) is a glassy material. It is important as the window of a cell for a sample containing water.
General Description
A yellow or red crystalline solid or powder. Combustible. Insoluble in water. Toxic by inhalation (dust) and ingestion.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
ARSENIC (III) SULFIDE is dissolved by alkalis and by hydrochloric acid (slowly). Decomposed by nitric acid. May react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. The reactions may be violent. ARSENIC (III) SULFIDE reacts with concentrated solutions of chloric acid with incandescence [Mellor Supp. II Part I:584 1956]. Generates toxic gaseous hydrogen sulfide on contact with acids.
Health Hazard
(Acute and sub-acute poisoning are not common.) Repeated inhalation causes irritation of nose, laryngitis, mild bronchitis. Ingestion causes weakness, loss of appetite, gastrointestinal disturbances, peripheral neuritis, occasional hepatitis. Contact with eyes causes irritation. Irritates skin, especially where moist; if not treated, may cause ulceration.
Fire Hazard
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Industrial uses
As2S3 (orpiment) and As2S2 (realgar) have been used as early as 2000 BC as drugs, for example, to cure cancerous tumours, ulcers and other diseases of the time. Later, Galen (130 200 AD) recommended the application of a paste of arsenic sulfide against ulcers.
Safety Profile
Confirmed human carcinogen with experimental tumorigenic data. A poison. Reacts violently with H202, (m03 + S). When heated to decomposition or on contact with acid or acid fumes it emits highly toxic fumes of S02, H2S, and As. Reacts with water or steam to emit toxic and flammable vapors.
Toxicology
Arsenic trisulfide is obtained by fusing arsenic trioxide with sulfur is marketed as orpiment. Or piment always contains unchanged arsenic tri oxide and, unlike the pure sulfide, is poisonous.
Potential Exposure
Arsenic trisulfide is used in the manufacture of glass, oil cloth, linoleum, electrical semiconductors, fireworks and used as a pigment.
Shipping
UN1557 Arsenic compounds, solid, n.o.s. inorganic, including arsenates, n.o.s.; arsenites, n.o.s.; arsenic sulfides, n.o.s.; and organic compounds of arsenic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
A strong reducing agent; avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and potassium nitrate mixed with sulfur, since violent reactions occur. Water contact forms hydrogen sulfide. Incompatible with acids, halogens. Contact with acids or acid mists releases deadly arsine gas.
Waste Disposal
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.
