Description
Summary:•Solid basic catalysts are used in transesterification reaction of acrylates.•Solid basic catalysts proved to be active and selective.•Ca(NO3)2/γAl2O3 was shown to be the most selective and could be reused up to 4 cycles.•Transesterification reaction of acrylates would be favoured by weakest basic sites. Different solid basic catalysts including CsF/αAl2O3, KF/αAl2O3, Ca(NO3)2/γAl2O3, NaNO3/γAl2O3, LiNO3/γAl2O3 were evaluated for the transesterification of ethyl acrylate by n-hexanol. All of them are active and selective in the transesterification reaction under mild conditions and without solvent, using a 1/1 molar ratio of reactants. Ca/γAl2O3 was shown to be the most selective of this set of catalysts and it could be recycled three times without lost of selectivity.
