固体超强酸TiO_2/SO_4^(2-)催化合成乙酸戊酯的研究

Catalytic Synthesis of Amyl Acetate with Solid Superacid TiO_2/SO_4^(2-)

对以固体超强酸TiO_2/SO_4^(2-)为催化剂,冰醋酸和戊醇为原料,催化合成乙酸戊酯的反应进行了研究,探讨了催化剂用量、醇酸比、反应时间等对酯化反应的影响。结果表明:醇酸摩尔比为1∶3,催化剂用量为1.5g,反应时间为1.5h,酯的产率达94.6％。

Using solid superacid TiO_2/SO_4^(2-) as catalyst , acetic acid and amyl alcohl as material , the synthesis of amyl acetate was studied. The influence factore, such as amount of catalyst, ratio of amyl alcohl and acetic acid , and reaction time,were also studied. The results showed that under the optimum conditions, the yield of esterfication was up to 94.6%.
