The Analysis of Rubber Vulcanizates—Identification of Amine Residues from Sulfenamide Accelerators by Thin Layer Chromatography

Abstract
The amine residues from sulfenamide accelerators can be identified in rubber vulcanizates by treatment of the latter with 4-chloro-7-nitrobenzo-2,1,3-oxadiazole (NBD-Cl) and examination of the products by thin-layer chromatography.
