Quantitative estimation of stabilizers in petroleum and its compounds using a model reaction

The possible application of a kinetic model for the quantitative estimation of the inhibiting ability of natural compounds of unknown composition and structure has been studied. The antioxidative ability of several petroleums and their high-molecular weight components has been quantitatively estimated. Petroleums of different types possess an inhibiting activity, which is mainly determined by their tar components. In their antioxidative ability these substances equal and sometimes even surpass the activity of known commercial stabilizers.
