1. normal- and pseudo-Dihydrothiamine were oxidized by various organic and inorganic oxidants having high redox-potential.
2. normal- and pseudo-Dihydrothiamine were oxidized by the dyes having the redox potentials higher than +0.40, +0.36, and +0.23V at pH 2.2, 5.0, and 7.0 respectively.
3. The absolute yield of thiamine produced by the oxidation of dihydrothiamine was about 50per cent under the experimental conditions described in this paper.
