XRD patterns show that the pillated derivative possesses a gallery height of 0.98nm. IR spectra exhibit that the Keggin structure of intercalated heteropolyanion is remained. The new material was found to be catalytically efficient for the esterification of phthalic anhydride with 2-ethyl hexanol.展开更多
