The oxidation products obtained in aerated, aqueous alpha-D-glucose solutions after irradiation with ultrasonic waves and gamma-rays were compared. Separation and identification were performed by gas chromatography/mass spectrometry and three methods for the derivatization of the products were used: (1) trimethylsilylation of the OH groups; (2) methoximation of the carbonyl groups followed by trimethylsilylation of the OH groups; (3) reduction of the carbonyl and carboxyl groups to alcohols by sodium borodeuteride, followed by trimethylsilylation of the OH groups. When using ultrasound and gamma-irradiation identical products were observed: D-glucono-1,4-lactone, D-glucono-1,5-lactone, D-arabino-hexos-2-ulose, D-ribo-hexos-3-ulose, D-xylo-hexos-4-ulose, D-xylo-hexos-5-ulose, D-glucohexodialdose and arabino-1,4-lactone. From the results it was concluded that in ultrasound and gamma-irradiation the same primary species and consecutive reactions are involved in product formation.
比较了在充氧的α-D-葡萄糖水溶液中，经超声波和γ射线辐照后得到的氧化产物。通过气相色谱/质谱进行分离和鉴定，并使用了三种产物衍生化方法：(1) OH基团的三甲基硅烷化；(2) 羰基的甲氧肟化，随后是OH基团的三甲基硅烷化；(3) 用硼氘化钠将羰基和羧基还原为醇，随后是OH基团的三甲基硅烷化。使用超声波和γ射线辐照时，观察到了相同的产物：D-葡萄糖酸-1,4-内酯、D-葡萄糖酸-1,5-内酯、D-阿拉伯己糖-2-酮糖、D-核糖己糖-3-酮糖、D-木糖己糖-4-酮糖、D-木糖己糖-5-酮糖、D-葡萄糖己二醛和阿拉伯糖-1,4-内酯。从结果得出结论，在超声波和γ射线辐照中，产物形成涉及相同的初级物种和连续反应。
