Description

Convenient reagent for the reduction of ketones to secondary alcohols.
Thiourea dioxide is an effective bleach when used alone or when used after hydrogen peroxide in a full bleaching process (Duffield, 1986; Cegarra et al, 1988). Bleaching with thiourea dioxide is not common practice but it is effective when used alone, and the process compares favorably with hydrogen peroxide bleaching. A formulation can include a commercial thiourea 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).
