Vulcanization & Accelerators
•An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. •Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization thus improving 'aged' properties of the rubber vulcanizates.
ACETONE DIPHENYLAMINE. The reaction rate, or carbocation stability, in S N 1 mechanism is 3° > 2° > 1° > CH 3 (no S N 1) so, tertiary alkyl moiety exists in lots of phenolic antioxidant compounds. Primary antioxidants are free radical scavengers which combine with peroxy radicals and break autocatalytic cycle.
