Description

<jats:title>Abstract</jats:title> <jats:p>Cs2.5H0.5PW12O40–SiO2 composite combined with (3-aminopropyl)triethoxysilane exhibited greater activity and selectivity for hydration of α-pinene at 333 K in a triphasic system (α-pinene/water/solid acid) compared to previously reported water-tolerant catalysts such as zeolites, polymer-resins (Amberlyst 15 and Nafion-H), oxides, and liquid acids such as H3PW12O40 and H2SO4. The selectivity toward alcohols, including mono- and dialcohols, was approximately 80% over Cs2.5H0.5PW12O40–SiO2 composite.</jats:p>
