SiO-SOH, with a surface area of 115 m/g and pore volume of 0.38 cmg, and 1.32 mmol H/g was used as a 20% / catalyst for the preparation of methyl salicylate (wintergreen oil or MS) from acetylsalicylic acid (ASA). A 94% conversion was achieved in a microwave reactor over 40 min at 120 °C in MeOH. The resulting crude product was purified by flash chromatography. The catalyst could be reused three times.
SiO-SOH，比表面积为 115 m²/g，孔体积为 0.38 cm³/g，氢量为 1.32 mmol/g，用作乙酰水杨酸（ASA）制备水杨酸甲酯（冬青油或 MS）的 20% /催化剂。在甲醇中于 120°C 下在微波反应器中反应 40 分钟即可实现 94%的转化率。所得粗产物通过快速色谱法纯化。催化剂可重复使用三次。
