| Abstract: | Dibutylphthalate has been prepared via esterification reaction in the presence of some solid acidic catalysts. Transition metal polyoxometalates with Keggin (K3[PMo6W6O40],
K3[PMo12O40], K4[SiMo12O40],
K4[SiW12O40], Na7[PW11O39]),
Wells-Dawson (K6[P2W18O62]), and
Preyssler structures (K14[NaP5W30O110])
have been synthesized and characterized. The reactivity of these catalysts has been studied for the preparation of dibutylphtalate by esterification reaction of
phthalic anhydride and 1-butanol. Among the various acidic catalyst used, K3[PMo6W6O40]
showed the
best reactivity and efficiency compared to other
catalysts. |
