Convenient reagent for the reduction of ketones to secondary alcohols.
Thioure a dioxide is an effective bleach when used alone or when used after hydro gen peroxide in a full bleaching process (Duffield, 1986; Cegarra et al, 1988). Bleaching with thioure a dioxide is not common practice but it is effective when used alone, and the process compares favorably with hydro gen peroxide bleaching. A formulation can include a commercial thioure a dioxide product, wetting agent and EDTA sequestering agent. Reductive bleaching is carried out at pH 7.0 at 70°C for 60 min (Duffield,
1986).

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, ammo nia, carbon mono xide, 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.
