reagents, still it has not fully been exploited by synthetic chemists since anhydrous (let alone pure) hydrogen peroxide requires hazardous preparation protocols. We have recently reported on the crystallization of serine and other amino acid perhydrates, thus paving the way for a new method for laboratory-scale production of anhydrous hydrogen peroxide solutions. Serine is insoluble in most organic solvents
过氧化氢是最通用的氧化试剂之一,由于无水(更不用说是纯净的)过氧化氢需要危险的制备方案,合成化学家仍未对其进行充分开发。我们最近报道了丝氨酸和其他氨基酸过水合物的结晶,从而为实验室规模生产无水过氧化氢溶液的新方法铺平了道路。丝氨酸不溶于大多数容易溶解过氧化氢的有机溶剂(例如甲醇,乙酸乙酯和乙酸甲酯)。而且,由于过氧化氢和丝氨酸的加合物在这些有机溶剂中不稳定,因此结晶的丝氨酸过水合物易于分解,得到过氧化氢和氨基酸的结晶沉淀物的无水溶液。然后,该步骤可在单个步骤中产生无水过氧化氢溶液。此外,氨基酸的过滤和挥发性溶剂(例如乙酸甲酯)的室温蒸发产生超过99%的过氧化氢。
