Three series of cesium salts of Keggin-type heteropoly acids (CsxH3+n-xPMo12-nVnO40, n=0, 1, 2, x=0.5~3.0) prepared by a solid synthesis method have been employed in the catalytic hydroxylation of benzene to phenol with H2O2. The effects of vanadium substitution number and cesium content on the catalytic activity, redox ability and hydrophobicity of the catalysts were studied. Cs2H3PMo10V2O40 exhibits high phenol yield (19.2%) and good reusability among the CsxH3+n-x- PMo12-nVnO40 catalysts.

Key words: heteropoly acid, cesium salt, benzene, hydroxylation, phenol
