Abstract: Amorphous carbon-based material prepared from expanded starch and p-toluene sulfonic acid has been examined as a novel strong solid acid catalyst. The catalytic performances were studied on esterification of oleic acids with ethanol. The effects of molar ratio of alcohol with oleic acid, catalyst concentration and reaction time were discussed. The results of XRD and acid-base titration indicated the incompletely carbonization of the mixtures of expanded starch and p-toluene sulfonic acid results in amorphous carbon consisting of small polycyclic aromatic carbon sheets. The results indicate that carbon-based catalysts are highly effective, minimally polluting and reusable catalysts that are highly suited to the production of biodiesel from waste oils with a high acid value. When the esterification reaction was carried out with molar ratio of ethanol to oleic acid of 8∶1, reaction time of 6.0 h and w(catalyst) 5.0%,the maximum yield of ethyl oleate was 83.78%. There was very little change in the catalytic activity of the regenerated catalyst, even after six cycles.
