liquid alkylated diphenylamine antioxidant - b. f. goodrich

Liquid alkylated diphenylamine antioxidant - B. F. Goodrich

The alkylation reaction with diphenylamine and the more reactive olefin converts the residual of less than 25, 20, or 15 wt. % diphenylamine to alkylated diphenylamine. If a temperature above 160° C. is used the reaction time is desirably less than 30 minutes or 1 hour so that the amount of octyl group cracking to butyl groups is minimized.

The activities of these three classes of antioxidant were compared in a fully formulated oil using a bench oxidation test at 165°C with soluble iron as a catalyst [91]. An alkylated diphenylamine was found to be marginally better than a hindered phenol, but a hindered cyclic secondary amine showed negligible activity.

Overview of commonly used materials for coal spontaneous

Overall, antioxidants capture free radicals and disrupt the chain reaction process to suppress CSC. However, certain antioxidants aggravate the risk of CSC because of their high activity. For example, diphenylamine powders in the air are susceptible to explosions. PEG and vitamin C oxidise at certain temperatures, which may exacerbate CSC. 4.2.
