本研究旨在阐明过氧苯甲酰（BPO）在某些溶剂中的稳定性。将BPO溶解于丙酮、乙腈（AcCN）、50%乙腈-50%蒸馏水（50%AcCN）、乙醇（EtOH）和甲醇（MeOH）中。将含有BPO的溶液在25 ℃下孵育8天。在甲醇中，BPO迅速分解为苯甲酸（BA）和苯甲酸甲酯（MeBA）的时间依赖性，而在丙酮，AcCN和50% AcCN中的BPO是相对稳定的。虽然BPO在EtOH中在最初的24小时内稍微稳定，但它随时间分解，从而产生作为BPO分解产物的BA和EtBA。这些结果表明，BPO在溶液中的稳定性依赖于溶剂，溶解在MeOH中的BPO分解速度最快。这些表明，BPO甚至可以在低于活化温度下通过溶剂分解以用于其溶解。
The purpose of this study was to clarify the stability of benzoyl peroxide (BPO) in some solvents. BPO was dissolved in acetone, acetonitrile (AcCN), 50% acetonitrile-50% distilled water (50% AcCN), ethyl alcohol (EtOH), and methyl alcohol (MeOH). Solutions containing BPO were incubated for eight days at 25 degrees C. In MeOH, BPO rapidly decomposed into benzoic acid (BA) and methyl benzoate (MeBA) time-dependently, whereas BPO in acetone, AcCN, and 50% AcCN was relatively stable. Although BPO in EtOH was slightly stable within the first 24 hours, it decomposed time-dependently such that BA and EtBA as decomposition products of BPO were produced. These results indicated that the stability of BPO in a solution was dependent on the solvent and the decomposition rate of BPO dissolved in MeOH was the fastest. These suggest that BPO can decompose even in lower-than-activation temperature by the solvent to use for its dissolution.
