Abstract: This paper presents a green methodology for synthesis of alkylated cardanol based on the green chemical principles, which incorporates environmental factors into the Friedel-Crafts alkylation reactions. Cardanol was used as a renewable source of phenol. The synthesised alkylphenols were characterised by gas chromatography mass spectrometry and their antioxidant potentialities were evaluated by using accelerated oxidation test. After the oxidation period (96 h and 120 h), the samples were analysed by ultraviolet-visible spectroscopy and the results showed that naphthenic hydrogenated 10, in the presence of the alkylphenols, exhibited reduction on the oxidative degradation. The proposed methodology considered the adoption of the first, fifth, sixth and seventh green chemical principles.
