Abstract The kinetics of oxidation of some aldoses, amino sugars and methylated sugars by tris(pyridine-2-carboxylato)manganese(III) have been studied spectrophotometrically in sodium picolinate–picolinic acid buffer medium. The reactions are first-order with respect to both manganese(III) and sugar concentrations, but independent with respect to sodium picolinate–picolinic acid buffer medium. The
摘要在吡啶甲酸钠-吡啶甲酸缓冲液中分光光度法研究了三(吡啶-2-羧甲基)锰(III)对某些醛糖,氨基糖和甲基化糖的氧化动力学。对于锰(III)和糖浓度而言,反应均为一级反应,但对于吡啶甲酸钠-吡啶甲酸缓冲液而言,反应是独立的。讨论了反应机理。
