methyl salicylate: sulfuric acid: aminosulfonic acid: p-toluenesulfonic acid: sodium bisulfate: 732 strong acidic cationic exchange resin
以浓硫酸、氨基磺酸、对甲苯磺酸、硫酸氮钠、732型强酸性阳离子交换树脂为催化剂,在不同的催化剂用量条件下合成水杨酸甲酯,分别考察了五种催化剂对产品的收率和折光率的影响。结果表明,以对甲苯磺酸为催化剂时,产品收率高、质量好。
以濃硫痠、氨基磺痠、對甲苯磺痠、硫痠氮鈉、732型彊痠性暘離子交換樹脂為催化劑,在不同的催化劑用量條件下閤成水楊痠甲酯,分彆攷察瞭五種催化劑對產品的收率和摺光率的影響。結果錶明,以對甲苯磺痠為催化劑時,產品收率高、質量好。

methyl salicylate was synthetised under the condition of different catalyst content with five catalysts ,which were sulfuric acid, aminosulfonic acid, p-toluenesulfonic acid, sodium bisulfate and 732 strong acidic cationic exchange resin. The influence of the catalysts to product yield and refractive index was examined. The result showed that the product yield and quality were the best with the catalyst of p-toluenesulfonic acid.
