Industrial grade cardanol is a yellow oil containing mostly cardanol with s
maller percentages of cardol and methylcardol, obtained by thermal treatmen
t and subsequent distillation of cashew nut shell liquid available in large
amounts in some developing countries. In order to find useful applications
of this widely available and renewable raw material in fine chemical proce
sses we undertook a kinetic investigation of the antioxidant activity of so
me hydrogenated cardanol and cardol derivatives, compared with that of anal
ogous commercial products.
