| Abstract: | A cheap cellulose-derived solid acid catalyst (Cellulose-SO3H), containing SO3H groups (1.69 mmol/g), was successfully prepared through sulfonation of incompletely carbonized cellulose. Various preparation variables exerted remarkable effects on the catalytic activity of the prepared catalyst, and the optimal preparation conditions were found as follows: carbonization at 400 oC for 15 h and subsequent sulfonation at 150 oC for 15 h. The resulting catalyst showed significantly higher activity for esterificat... |
