Acidic properties of CaO-SiO₂ binary oxide catalyst and activity for acid catalysis

A series of CaO-SiO₂ catalysts were prepared by coprecipitation from the mixed solution of calcium chloride and sodium silicate. The addition of CaO to SiO₂ caused the increase of acidity and the shift of O-H and Si-O stretching bands of the silanol group to a lower frequency in proportion to the CaO content. The acid structure of CaO-SiO₂ agreed with that proposed by Tanabe et al.. Catalytic activity for 2-propanol dehydration and cumene dealkylation increased in relation to the increase of acidity and band shift to a lower frequency.

Keywords:CaO-SiO₂ catalyst;Acid structure;2-propanol dehydration;Cumene dealkylation;Acidity
