ZnO/ionic liquid catalyzed biodiesel production from renewable and waste lipids as feedstocks [PDF]

open access: yes, 2019
A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as a heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer ...
