摘要
在微波辐射下,以A lC l3.CuSO4固体超强酸为催化剂合成乙酸正戊酯。合成反应的最佳条件是:乙酸和正戊醇的物质的量比为1¨2.0,催化剂用量为1.50 g无水CuSO4和1.25 g无水A lC l3的混合物,微波输出功率为729W,反应时间为16 m in。在此反应条件下,乙酸的酯化率为95.6%,酯收率为89.6%。
The synthesis conditions of amyl acetate are studied in the presence of solid superacid AlCl3. CuSO4 as catalyst under microwave radiation. The best conditions are as follows：the mole ratio of acetic acid and 1-Pentanol is 1 ： 2.0 （mol/mol）, the amount of catalyst is the complex of Copper（Ⅱ） sulfate anhydrous 1.5 g and Aluminum chloride anhydrous 1.25 g,radiation power 729 W, reaction time 16 min. Under above conditions, 95. 6% of acetic acid is converted, the yield chloroacetates is 89.6 %.
