Ma, Tian's first work related to ionic liquids catalzed in-situ transesterification of wet algae for biodiesel production has been published as full article in ACS Sustainable Chemistry & Engineering, 2020, 8:4647-4657.https://pubs.acs.org/doi/10.1021/acssuschemeng.0c00730
In this study, we are trying to maximize the H-bonding interactions of BAILs-cellulose to neutralize the negative effect of water on in-situ transesterification via enhancing the cellulose extractions of BAILs. For this reason, the effects of H-bonds between BAILs including [Bmim][H2PO4], [Bmim]2[HPO4], [Bmim][HSO4] and cellulose under different methanol and water conditions on cellulose extractions are experimentally and theoretically investigated.
Four significant outcomes of this work are: (1) The amount of cellulose extracted in BAILs decreasing in the order of [Bmim][H2PO4] > [Bmim]2[HPO4] > [Bmim][HSO4], is contrary to the variation of their thermal stabilities and crystallinities caused by varied H-bonding of BAILs-cellulose. (2) The increase of methanol is positive to cellulose extractions in [Bmim][HSO4] while negative to those in [Bmim][H2PO4] and [Bmim]2[HPO4]. (3) The results of DFT calculations are consistent with the variations of cellulose extractions in different BAILs. (4) The biodiesel yields are varied differently due to the competition of H-bonding of BAILs-cellobiose and deprotonation of BAILs under different methanol and water conditions.
Congrats to him, and we wish him a great breakthrough next time!
