| Abstract: | The synthesis conditions of isopentyl acetate are studied in the presence of solid superacid SO2-4/TiO2 as catalyst under microwave irradiation.The best conditions are as follows:the mole ratio of acetic acid and 3-Methyl-1-butanol is 1:2 (mol:mol),the amount of catalyst is 1.5 g,irradiation power is 729 W,the reaction time is 12 min.Under the above conditions,94.7% of acetic acid is converted,the yield chloroacetates is 89.7%. |
