Abstract : Earlier research has shown that compounds of the naphthalene series display more favorable oxidation inhibiting properties than the compounds of the phenol series. In this research individual alkylnaphthols were synthesized and their oxidation inhibiting properties were investigated. It was shown when methyl groups are introduced into alpha- and beta-naphthols the oxidation inhibiting property of the alkylnaphthol series increases. The oxidation inhibiting property is further enhanced by the introduction of an isopropyl group. The position of the methyl group in the napthol series has a significant effect on the oxidation inhibiting properties of alkylnaphthols. In this connection it was found that 4-methyl-1-naphthol and 6-methyl-2-naphthol have the strongest oxidation inhibiting properties. Among other compounds 7-methyl-1-naphthol, 4-methyl-1-naphthol and 5-isopropyl-7-methyl-1-naphthol are superior in their oxidation inhibiting properties to the antioxidants which are presently used in industry and may be new effective chain reaction inhibitors. In this investigation the oxidation inhibiting property of a substance was evaluated from the effect which it produces on the induction period of oxidation of paraffin at 170C.
