| Abstract: | The catalytic properties of SO 2- _4/Fe_2O_3-SiO_2 solid superacid in the esterification of acetic acid and butanol were systematically studied. The optimal reaction conditions were obtained: mole ratio of Fe to Si in mixed oxides = 1∶2, impregnant concentration of H_2SO_4=1 mol/L, calcining at 500 ℃ for 3 h, amount of catalyst 0.8 g, reaction time 4 h, conversation of HAc 96.3%. Under these conditions S_2O 2- _8/Fe_2O_3-SiO_2 solid superacid were prepared and the catalytic activity were also studied , it was found that this solid superacid has higher catalytic activity than SO 2- _4/Fe_2O_3-SiO_2, the conversation of HAc reached 98.6%. |
