flowing scalable production of sulfenamides by active site-tuned

Flowing scalable production of sulfenamides by active site-tuned

The flowing production of sulfenamide rubber additives with performance beyond industry norms is inspiring, yet it remains challenging to conquer the generally low efficiency, harsh reaction conditions, and complex equipment needed in the traditional industrial synthesis process.

Select Accelerators for Rubbers

The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines. Part or all of the sulfur may be replaced by an accelerator that is also a sulfur donor such as a thiuram disulfide.

n-cyclohexylbenzothiazol-2-sulphenamide

N-Cyclohexylbenzothiazol-2-sulphenamide

CBS is exclusively used as vulcanization accelerator in rubber goods manufacture. Vulcanization transforms the rubber from the thermoplastic into the elastomeric state at temperatures between 150 and 200 ¡ãC. CBS is loaded to the rubber in concentrations of 0.5¨C 1% (ww) but it breaks down during the curing process.
