Improving synthetic hindered phenol antioxidants: learning
Most commercial synthetic hindered phenolic antioxidants are based upon 2, 6-di-tert-butyl-4-methyl-phenol (BHT). We compared the antioxidant e†ciency of BHT with that of 2, 6-di-tert-butyl-4-methoxyphenol (BHA) and found that BHA was 94% more e†cient. This implies that it may be advantageous to make new commercial hindered phenolic anti-
Interaction of a Synthetic Hindered-Phenol with Natural Fuel
The synthetic hindered-phenol antioxidant BHT is added at concentrations of 3−50 mg/L. The individual and combined effects of natural and synthetic antioxidants on paraffin autoxidation are determined on the basis of increased reaction time required to deplete initial dissolved O 2 by 50%.
Improving synthetic hindered phenol antioxidants: learning
Many synthetic hindered phenol type antioxidants such as Irganox® 1010, 1330, 3114, 1076, 259, 1098 and 3125 rely on the BHT functionality for their antioxidant properties. The synthetic hindered phenols are made by joining BHT units together to increase the molecular weight and thus decrease the volatility and extractability of such antioxidants.

Strategically designed macromolecules as additives for high
The thermal cracking performance of JP-10 under supercritical condition with the macromolecules was evaluated in a tube reactor. Two widely used conventional hindered phenol antioxidants, 2,6-di-tert-butyl-4-methylphenol (BHT) and 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate (Antioxidant 1076), were chosen for comparison. 2. Experiment 2.1.
Interaction of a Synthetic Hindered-Phenol with Natural Fuel
We report empirical changes in autoxidation caused by (1) introducing a hindered phenol antioxidant (BHT), (2) adding a phenylenediamine antioxidant mixture (A0−24), (3) introducing natural fuel
Analysis of the antioxidant butylated hydroxytoluene (BHT)
The antioxidant 3,5-di-tert-butyl-4-hydroxy-toluene (BHT) is widely used as an additive to increase the tenability of food and plastics. BHT is degraded to 3,5-di-tert-butyl-4-hydroxybenzaldehyde
