| 摘 要： | 以硫酸处理杭锦2^#土制得的活性白土为载体，采用传统漫渍法制备了SO4^2-／杭锦2^#土固体超强酸，将该固体酸催化剂用于冰乙酸和正丁醇的酯化反应，考察了反应条件对酯化率的影响．结果表明：在醇、酸摩尔比为2：1．催化剂用量为0．6g，反应温度为90℃。反应时间为2h时，酯化率可达99．2％．显示出与硫酸为催化剂相当的活性。且催化剂可重复使用． |

| Abstract: | SO4^2-/Hangjin 2^# clay solid superacid catalyst was prepared by impregnation method using activated clay （sulfuric acid-treated hangjin 2^# clay） as the support, n-butyl acetate was synthesized from n-butanol and acetic acid with SO4^2-/Hangjin 2^# clay as catalyst, The influences of reaction condition on the conversion of ester were investigated. The results reveal that the optimum conditions are：the mass of catalyst is 0.6g; the molar ratio of n-butanol to acetic acid is 2：1, reaction temperature is 90℃,reaetion time is 2 h. Under these conditions, the conversion of ester is 99.2%.catalytic activity of SO4^2-/Hangjin 2^# clay is almost equal to sulfuric acid and the catalyst can be used repeatedly. |
