Full TextAbstract
H4[SiW12O40], H6[P2W18O62] and H14[NaP5W30O110] were investigated. The mentioned heteropolyacids were prepared by the reaction between sodium molybdate and/ or tungstate in presence of PO4 3- or SiO3 2- ions, and then were characterized by UV-Vis and IR spectroscopy. Consequently, catalytic application synthesized heteropolyacids were noticed in esterification of phthalic anhydride at presence of 1-butanol. The reaction time and the amount of catalyst were varied in the range of 2- 6 h and 0.1-0.8 g, respectively. The H6[P2W18O62] catalyst had the best reactivity and efficiency among the investigated catalysts. It is to be noted that H3[PMo12O40] showed lower activity. Then, reaction conversion reaches to about 96% conversion within 5 h and 0.7 g using H6[P2W18O62] catalyst. Finally, it can be concluded that application of those heteropolyacids caused relatively simplification of the esterification process, easy to work-up, lower cost, and lowering the acidic wastes, which all is environmentally greener.
