  • What is the function of antioxidant IPPD?
  • Function mechanism of antioxidant IPPD ( R represents alkyl) According to Scheme 3, we can conclude that the 1 mol antioxidant IPPDs (molecular weight = 226) contain 2 mol labile hydrogens, each of which can scavenge 1 mol peroxy radicals to terminate 1 mol free radical chain reactions.
  • Does P-ASALA protect Nr against autoxidation?
  • Except for functioning as a labile-hydrogen donor which is similar to antioxidant IPPD in protecting NR against autoxidation, p -ASALa has strong coordination abilities and large coordination numbers, resulting in the high efficiency in enhancing the thermal-oxidative stability of NR.
  • Does P-ASALA improve thermal oxidative stability of NR?
  • After aging at 353 K for 144 h, the fractions of oxygenic carbon atoms in Sample B are all lower than those in Sample A, indicating that p -ASALa is effective in improving the thermal-oxidative stability of NR by delaying the generation of thermal-oxidative aging products, e.g., ketone, ether, and ester.
  • Can mixed Antioxidants improve thermal-oxidative stability of NR?
  • The results all showed that, compared with pure antioxidant IPPD, the same mass of mixed antioxidants could indeed improve the thermal-oxidative stability of NR.
