크롬산 암모늄 C화학적 특성, 용도, 생산
화학적 성질
Ammonium chromate is a yellow crystalline compound which can be used in solution, which is yellow with an ammonia odor.용도
Ammonium chromate, is used in photography as a sensitizer for gelatin coatings. It's often used in photography, textile printing, and fixing chromate dyes on wool. It is also used as an analytical reagent, catalyst.위험도
Toxic by inhalation, strong irritant. Con- firmed carcinogen.Safety Profile
A poison. Mutation data reported. See also CHROMIUM COMPOUNDS. A powerful oxidizer. An explosion hazard when shocked or heated. When heated to decomposition it emits toxic fumes of NH3, Cr03, and NOx. Incompatible with reducing agents.잠재적 노출
It is used to inhibit corrosion and in dyeing, photography and many chemical reactions. Used as a fungicide and fire retardant.운송 방법
UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.Purification Methods
Crystallise it from weak aqueous ammonia (ca 2.5mL/g) by cooling from room temperature. It loses NH3 on heating to form ammonium dichromate. POISONOUS.비 호환성
A strong oxidizer and an explosive. Contact with combustible, organic and other readily oxidizable substances may cause fire and explosions. Hydrazine, other reducing agents. Corrosive to metals.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. Addition of a large volume of a reducing agent solution (hypo, bisulfite or ferrous salt, and acidify with 3 M sulfuric acid). When reduction is complete, flush to drain with large volumes of water.크롬산 암모늄 준비 용품 및 원자재
