AMMONIUM CHROMATE Usage And Synthesis
Chemical PropertiesAmmonium chromate is a yellow crystalline compound which can be used in solution, which is yellow with an ammonia odor.
UsesSensitizing gelatin in photography, in textile printing pastes, in fixing chromate dyes on wool, and as a reagent in analytical chemistry.
HazardToxic by inhalation, strong irritant. Con- firmed carcinogen.
Safety ProfileA 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.
Potential ExposureIt is used to inhibit corrosion and in dyeing, photography and many chemical reactions. Used as a fungicide and fire retardant.
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 30 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
ShippingUN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Purification MethodsCrystallise it from weak aqueous ammonia (ca 2.5mL/g) by cooling from room temperature. It loses NH3 on heating to form ammonium dichromate. POISONOUS.
IncompatibilitiesA 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.
Waste DisposalConsult 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.
