Variation of stoichiometric factor n: (A) during the autoxidation of Cumene (1.8 M) initiated by AIBN (0.05 M) in acetonitrile at 30° C (red), and upon addition of: 1% water (black), HNTs 0.25 mg/mL (green), 1% water and HNTs 0.25 mg/mL (pink) inhibited by variable amount of AH2 (7.0 × 10−7 M to 6.4 × 10−5 M, red, black, green, and pink), or inhibited by HNT/AH2 (blue); (B) during the autoxidation of THF (3.1 M) initiated by AAPH (25 mM) in phosphate buffer 0.1 M pH = 7.4 at 30 °C (black) and upon addition of HNTs 0.25 mg/mL (green), inhibited by variable amount of antioxidant AH2 (1.4 × 10−6 M to 8.1 × 10−5 M, black and green) or inhibited by HNT/AH2 (blue).
