چکیده
|
This paper reports the preparation of so 4 2-/ fe 2o 3-tio 2-nd 2o 3 (designated as sftn) by combustion method,which were characterized by ft-ir and nh3-tpd techniques respectively. the results showed that sftn kept the typical covalence s=o bond structure of so 4 2-/m xo y(sm) solid acids,and both lewis and brønsted acid sites existed; sftn exhibited higher activity for the esterification of acetic acid and menthol,with 98.30% yield of menthyl acetate. the higher activity was attribute to the enhancement of acidic properties of the catalyst by the addition of nd 2o 3 to so 42-/fe 2o 3-tio 2 (sft).
