transesterification, the free water and produced water in the
greases did not affect the conversion of biodiesel since
GDTCSA had a strong hydrophobicity.

Conclusions
In summary, the carbon-based solid acid Functionalized with
NH2+ and SO3H Groups was used as a highly activity catalyst for
transesterification. The carbon material showed broad
substrate scopes for transesterification under mild reaction
conditions. What’s more, the carbon-based solid acid could be
used to catalyze vegetable oil and animal fat to prepare
biodiesel by the simultaneous esterification and
transesterification. And the catalyst could be recovered and
recycled without any significant loss in activity during ten
cycles.
