摘要
Pore-engineered silica-alumina was synthesized for the conversion of longifolene to isolongifolene, and the effects of texture and surface properties on the activity were examined. The acidity and texture of the modified silica-alumina play a vital role in governing the catalytic isomerization of longifolene to isolongifolene. A conversion of 97% of longifolene with 95% selectivity has been achieved.
