Sodium chromate tetrahydrate Chemical Properties,Uses,Production
Chemical Properties
yellow deliquescent crystals
Uses
Corrosion inhibitor, pigment manufactureSodium chromate tetrahydrate is used as a corrosion inhibitor, wood preservative and an auxiliary in textile industry. It serves as an oxidant, which is used to prepare carboxylic acids and ketones from primary and secondary alcohols respectively. Further, it is used as a starting material to prepare other chromium compounds and as a catalyst in organic synthesis especially pharmaceuticals and agro chemicals.
General Description
Odorless bright yellow deliquescent crystals. Aqueous solutions are alkaline.
Air & Water Reactions
Deliquescent. Water soluble.
Reactivity Profile
Sodium chromate tetrahydrate is a strong oxidizing agent. Incompatible with strong acids . Contact with combustible materials may lead to a fire. Toxic chromium oxide fumes may form in fire [USCG, 1999].
Fire Hazard
Literature sources indicate that Sodium chromate tetrahydrate is nonflammable.
Potential Exposure
Used to make dyes, inks, pigments, and other chromates; in leather tanning, a corrosion inhibitor in circulating water systems; metal treatment; a drilling mud additive; chemical intermediate for chromium catalysts; colorimetry, oxidizing agent; bleaching agent; an algicide, fungicide, insecticide; in wood preservation.
Shipping
UN3087 Oxidizing solid, toxic, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, 6.1-Poisonous materials, Technical Name Required. UN3085 Oxidizing solid, corrosive, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, 8-Corrosive material, Technical Name Required.
Purification Methods
Crystallise the chromate from hot water (0.8mL/g). It is deliquescent.
Incompatibilities
Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, alcohols, and carbon dioxide, releasing highly toxic and flammable hydrogen cyanide gas. Aqueous solution is a strong base; it reacts violently with acid and is corrosive. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Absorbs moisture from the air forming a corrosive syrup. Corrosive to active metals, such as aluminum, copper, and zinc. Under acid conditions, sarin hydrolyzes to form hydrofluoric acid.
Waste Disposal
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to 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. Add strong alkaline hypochlorite and react for 24 hours. Then flush to sewer with large volumes of water.
