- Solvent effects in esterification of phthalic anhydride on sulfated titania-based solid acid
-
Esterification of phthalic anhydride with 2-octanol has been studied in the presence of sulfated titania. This study shows that sulfated titania has strong catalytic effects on esterification reactions. The catalyst was characterized with x-ray diffraction, FT-IR, Brunauer Emmett Teller, SEM and thermogravimetric methods. The effect of the type and volume of solvent has been investigated. Three solvents were used in this work: acetonitrile, dimethyl sulfoxide (DMSO) and an ionic liquid, 2-hydroxy ethylammonium formate. The results show that addition of various solvents has significant effects on the reaction rate of phthalic anhydride. DMSO and 2-hydroxy ethylammonium formate enhance the reaction rate but acetonitrile reduces it.
