Abstract

KBr3 oxidation of xylose, in presence of H2SO4, follows first order kinetics in [KBrO3] and [xylose], and second order in [H2SO4]. The acid-catalyzed reaction gives aldonic acid as product. A mechanism consistent with temperature, solvent, higher acidity and salt effects has been proposed. Thermodynamic constants have been calculated.

Abstract

Окисление ксилозы KBrO3 в присутствии H2SO4 подчиняется кинетике первого порядка по [KBrO3] и [ксилоза] и второго порядка по [H2SO4]. Кислотно-катализированная реакция результирует альдоновую кислоту в качестве продукта. Предложен механизм, согласующийся с влиянием температуры, растворителя, высокой кислотности и солей. Рассчитаны термодинамические константы.
