Calcium chlorate Usage And Synthesis
Chemical PropertiesCalcium chlorate forms white to yellow deliquescent crystals.
UsesPhotography, pyrotechnics, dusting powder to kill poison ivy, herbicide.
General DescriptionA white crystalline solid. Calcium chlorate forms a very flammable mixture with combustible materials and this mixture may be explosive if the combustible material is finely divided. The mixture can be ignited by friction. Contact with strong sulfuric acid can cause fires or explosions. When mixed with ammonium salts, spontaneous decomposition and ignition may result. Prolonged exposure of the material to fire or heat can result in an explosion. Calcium chlorate is used in photography, in pyrotechnics, and as a herbicide.
Air & Water ReactionsWater soluble.
Reactivity ProfileAn oxidizing agent. Liberates explosive chlorine dioxide gas in the presence of strong acid. Heating a moist mixture with a dibasic organic acid liberates chlorine dioxide and carbon dioxide. Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination with finely divided aluminum can explode by heat, percussion, or friction [Mellor 2:310 1946-47].
HazardOxidizer, dangerous fire risk, forms explo- sive mixtures with combustible materials.
Health HazardInhalation of dust causes irritation of upper respiratory system. Dust irritates eyes and skin. Ingestion causes abdominal pain, nausea, vomiting, diarrhea, pallor, shortness of breath, unconsciousness.
Fire HazardBehavior in Fire: When involved in a fire, may cause an explosion. Irritating gases may be generated when heated.
Safety ProfileModerately toxic by ingestion and intraperitoneal routes. A powerful oxidant. Incompatible with Al, As, C, Cu, charcoal, MnO2, metal sulfides, S, dibasic organic acids, organic matter, P. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORATES for fire, disaster, and explosion hazards.
Potential ExposureCalcium chlorate is used in making fireworks, herbicides (weed killers) and in photography. Incompatibilities: A strong oxidizer. Reacts, possibly with risk of fire and explosion, with acids (especially organic acids), reducing agents; aluminum, arsenic, chemically active metals; combustible materials; ammonium compounds; charcoal, copper, cyanides; manganese dioxide, metal sulfides; phosphorus, sulfur
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 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.
ShippingUN1452 Calcium chlorate, Hazard Class: 5.1; Labels: 5.1-Oxidizer. UN2429 Calcium chlorate, aqueous solution, Hazard Class: 5.1; Labels: 5.1-Oxidizer
IncompatibilitiesCalcium chlorate is used in making fireworks, herbicides (weed killers) and in photography. Incompatibilities: A strong oxidizer. Reacts, possibly with risk of fire and explosion, with acids (especially organic acids), reducing agents; aluminum, arsenic, chemically active metals; combustible materials; ammonium compounds; charcoal, copper, cyanides; manganese dioxide, metal sulfides; phosphorus, sulfur
Waste DisposalFor barium chlorate, the UN recommends using a vast volume of a reducing agent (bisulfites, ferrous salts or hypo) followed by neutralization and flushing to the sewer with abundant water. This should be applicable here as well.
