| Abstract: | With phosphoungstic acid as a catalyzer and 4A mo lecular sieve as dehydrator and microwave irradiation, ethanoic acid and buryl alcohol were directly synthesized into butyl acetate. The amount of catalyzer, microwave irradiation power and time, the ratio of ethanoi cacid and bu ryl acohol and its ethanoic for the conversion rate were examined. The optimum r eaction conditions were as follows: the ratio of number of moles ethanoi acid an d phosphotungstic was1:0.001664, microwave irradiation power and time were 335 W and 15 min. respectively. The ratio of number of moles ethanoic acid and buryl alcohol was 1∶1.5. The conversion rate under the condition was 96%. |
