CN106316981A Preparation method of N-cyclohexyl-2
The invention belongs to the technical field of fine chemical engineering, and concretely relates to an oxidant-free preparation method of N-cyclohexyl-2-benzothiazolesulfenamide (CBS). The CBS is synthesized from benzothiazole disulfide (a sulfuration promoter DM) and cyclohexylamine by using an inorganic or organic alkaline catalyst, no oxidant is needed in the reaction

Accelerant Wikipedia
Accelerants are substances that can bond, mix or disturb another substance and cause an increase in the speed of a natural, or artificial chemical process. Accelerants play a major role in chemistry—most chemical reactions can be hastened with an accelerant. Accelerants alter a chemical bond, speed up a chemical process, or bring organisms back to homeostasis.

Vulcanization & Accelerators Nocil
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 vulcanizationand thus improving 'aged'
