【摘要】利用纳米固载型杂多酸HPA/TiO2 WO3为催化剂,在微波辐射下快速合成了丁酸丁酯。实验结果显示,当微波功率为800W,催化剂用量为0 2g,醇酸比为2 6∶1,反应时间为20min,酯收率超过94%。更多还原

【Abstract】 n-Butyl butyrate was synthesized by supported heteropolyacid catalyst HPA/TiO₂-WO₃ under microwave irradiation. The experiment show that when the power of microwave irradiation was 800 W, amount of catalyst was 0.2 g, molar ratio of alcohol to acid was 2.6/1, reaction time was 20 min, yield of the product was 94%.更多还原
