General Description
White crystalline solid. Insoluble in water. Specific gravity 0.85. Hence floats on water.

Hazards

Reactivity Alerts
none
Air & Water Reactions
Dust explosion is possible. (USCG, 1999). Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Dust explosion is possible. (USCG, 1999)
Health Hazard
May be harmful by inhalation, ingestion or skin absorption. Material is irritating to mucous membrane and upper respiratory tract. Causes eye and skin irritation. (USCG, 1999)
Reactivity Profile
A weak carboxylic acid. Neutralizes bases with the evolution of substantial amounts of heat to produce water plus a salt. Reacts with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Can generate flammable and/or toxic gases and heat by reaction with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Reacts in with aqueous solutions of nitrites and thiosulfates (to give H2S and SO3) and dithionites (to give SO2) and heat. Reaction with solutions of carbonates and bicarbonates generate a harmless gas (carbon dioxide) but still heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. May initiate polymerization reactions. May serve as a catalyst.
