Dibutyl-4-methylphenol

Oxidation of isoeugenol with (BPA)Cu(II)Clzin ethanol gave the ortho-ortho coupling dimer and the aldehyde derivatives, On the other hands, oxidation of isoeugenol in acetic acid Hz O gave the adduct of two molar isoeugenol and one molar acetic acid. When 2,6-dibutyl-4-methylphenol was oxidized in the system of copper(II) acetate-pyridine quinone methide derivatives were produced.

The antioxidative effect of the obtained phenolics fractions on a selected diester DBS (dibutyl sebacate) was carried out following the ASTM D 4871 standard. This universal test allows the examination of oxidation stability of a liquid test sample. The samples of uninhibited DBS and after addition of ca. 1,000 ppm of a selected antioxidant agent (BHT, extract A, extract B) were prepared and examined. Commercial BHT (2,6-ditertbutyl-4-methylphenol) was used as a standard antioxidant for comparison. Investigated samples with a mass of 100 g were subsequently placed in the reaction vessel and oxidized at 150°C by flowing air stream (100 cmVmin).
