Abstract
Catalytic activity of silica gel and aluminium oxide impregnated with sulphuric acid (H+-SiO2 and H+-Al2O3, respectively) in the reaction of acid-catalysed isomerization of caryophyllen oxide was investigated. It was established that the activity of H+-SiO2 is much higher than that of H+-Al2O3 and is comparable with the activity of concentrated sulphuric acid. For silica gel H+-SiO2, the dependence between the catalytic activity and the size of silica gel particles was revealed.
