Thiourea dioxide Usage And Synthesis
Chemical Properties white crystalline powder
Usage Convenient reagent for the reduction of ketones to secondary alcohols.
General Description A white or light-yellow odorless crystalline powder. Mp:126°C. Soluble in water (27 g / L at room temperature). Decomposes exothermically at temperatures above 126°C with the emission of noxious gases (sulfur oxides, ammonia, carbon monoxide, nitrogen oxides and hydrogen sulfide) and carbon dioxide. Extended exposure to temperatures above 50°C and moisture may cause visible decomposition. Irritating to skin and mucous membranes. Corrosive to eye tissue. Used in leather processing, the paper industry, photographic industry, and in textile processing as a bleaching agent.
Air & Water Reactions Soluble in water
Reactivity Profile Thiourea dioxide is a reducing agent and a derivative of sulfinic acid (a weak inorganic acid). Decolorizes and bleaches materials by chemical reduction. Stable under normal temperatures and pressures. May decompose on exposure to moist air or water. Incompatible with strong oxidizing agents, strong bases. Aqueous solutions are acidic and corrosive.
Health Hazard Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
Fire Hazard Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
