Ketalization of ketones with diols catalyzed by metal(IV) phosphates as solid acid catalysts

Metal(W) phosphates of tin, zirconium and titanium in different morphological forms, viz. amorphous, calcined and crystalline, have been used as catalysts for selective ketalization of ketones. A comparative study of the catalysts for the aforementioned reaction has been carried out to understand the effect of the composition and morphology on their catalytic activity.
