| Abstract: | The esterification of anhydride with n-butanol over solid acid catalyst using zeolites as supporter was studied. The effects of catalytic activity, selectivity and stability were investigated. The experimental results show that the conversion of anhydride can reach 98% and the selectivity of DBP is 100% under optimum. Moreover the catalyst can be used repetitively. The structure and acidic properties are characterized by IR in frame work region, XRD, Py IR and NH 3 TPD. |
