摘要
研究了以ZrO2 /SO2 - 4固体超强酸催化水杨酸与甲醇合成水杨酸甲酯的反应。在沸腾条件下连续滴加甲醇 ,控制甲醇的滴加速度与甲醇的馏出速度相等 ,反应 6h ,水杨酸的转化率达81 6%。
The reaction of methol and salicylic acid with solid superacid ZrO 2/SO 2- 4 as catalyst was studied. Continuously dropped methol under boiling condition, and controlled the speed of dropping and distilling to be same for 6?h. The conversion of salicylic acid reaches to 81.6%.
