Abstract:Esterification of oleic acid (OA) and glycerol (GLY) is studied in the absence and in the presence of the organotin(IV) catalysts (CAT) dibutyltin dichloride (Bu2SnCl2), butyltin trichloride (BuSnCl3), dibutyltin dilaurate (Bu2SnLau2), butyl stannoic acid (BuSnO(OH)), and di‐n‐butyl‐oxo‐stannane (Bu2SnO). The reactivity order observed at 180 °C using a OA/GLY/CAT molar ratio of 1/1/0.01 was BuSnCl3 > Bu2SnLau2 > Bu2SnCl2 > Bu2SnO > BuSnO(OH), and a kap of −0.6237 h−1 is obtained for BuSnCl3. The estimated acti… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
