Abstract
The conversion of caryophyllene upon contact with Al2O3 and SiO2 impregnated with sulfuric acid was carried out, and the components of the resulting mixtures were identified. Having in hands such “standard” mixtures greatly facilitates identification of components of sesquiterpene fractions of essential oils and other mixtures of natural origin. The catalytic activity of silica gel impregnated with sulfuric acid (H+-SiO2) in the acid-catalyzed isomerization of caryophyllene is significantly higher than that for H+-Al2O3 and is comparable with the activity of concentrated sulfuric acid.
