ZINC CHLORATE

Chemical properties

Colorless to yellowish crystals. Deliquescent, decomposes at 60C. Soluble in water, alcohol, glycerol, and ether

General Description

A white crystalline solid. May explode under prolonged exposure to heat or fire.

Air & Water Reactions

Water soluble.

Reactivity Profile

ZINC CHLORATE is an oxidizing agent. Forms flammable mixtures with combustible materials; these mixtures may be explosive if the combustible material is finely divided. Contact with concentrated sulfuric acid can cause fires or explosions. Heating with a moist dibasic organic acid liberates chlorine dioxide and carbon dioxide [Bretherick 1979. p. 100] 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]. A mixture with charcoal (or other finely divided organic material) may ignite or explode. Ignition or explosion may also be caused by friction or shock [U.S. Army Ordnance Safety Manual 1951].

Health Hazard

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile

A powerful oxidizer. Probably a skin, eye, and mucous membrane irritant. The tetrahydrated salt explodes at 60°C. Explosive reaction with copper(II) sulfide. Can react violently with Al, Sb2S3, As, C, charcoal, Cu, MnO2, metal sulfides, dibasic organic acids, organic matter, P, S, H2SO4. Incandescent reaction with antimony(III) sulfide, arsenic(III) sulfide, tinpI) sulfide, tin(IV> sulfide. When heated to decomposition it emits toxic fumes of CT and ZnO.
