Abstract

TI(III) oxidation of cellobiose in the presence of H2SO4 in aqueous acetic acid is first order in each reactant and is acid catalyzed. TI(OAc) 2 + is the active species. Products identified are gluconic acid and glucose. A mechanism consistent with the temperature, solvent, acidity and salt effects is been proposed.

Abstract

Окисление целлобиозы TI(III) в присутствии H2SO4 в водной уксусной кислоте подчиняется закону первого порядка по каждому реагенту и катализизируется кислотами. Активными частицами являются TI(OAc) 2 + . Глюконовая кислота и глюкоза идентифицировались в качестве продуктов. Предлагается механизм, согласующийся с эффектами температуры, растворителя, кислотности и солей.
