Abstract

2-(tert-butyl)-4-(((4-methoxyphenyl)-phenol (Ia) and 2-(tert-butyl)-4-(4-nitrophenyl)diazenyl(Ib) were produced as the local oil supply antioxidant and examined. The structures were clarified using standard analytical techniques (elemental analysis FT-IR, 1H-NMR and mass spectroscopy). Oxidation stability was investigated before and after adding various Ia and Ib concentrations through change in total acid number (TAN) and viscosity. The findings were discussed and the effectiveness classified as follows: Ia > Ib. Ia > Ib. A good agreement with the experimental findings was shown by the quantum chemical calculations (E-HOMO, E-LUMO and E-LUMO-E-HOMO).
