| Abstract: | Esterification reaction,performed with propionic acid and 1-butanol,was researched,the solid superacid SO42-/Fe2O3 was preparek by calcining Fe2SO4.7H2O directly.The results indicate that the catalytic activity and selectivity and better solid acidity of SO42-/Fe2O3.Appropriate reaction condition is proposed,the molar ratio of alcohol,acid is 1.0∶1.2,catalyst consumption is 8 g per molar hexanol,reaction time is 2 h,and the esterification rate is above 96%. |
