ISO 11235:2016 specifies the methods to be used for the evaluation of sulfenamide accelerators: - MBTS: benzothiazyl disulphide; - CBS: N-cyclohexylbenzothiazole-2-sulfenamide; - TBBS: N-tert-butylbenzothiazole-2-sulfenamide; - DIBS: N,N'-diisopropylbenzothiazole-2-sulfenamide; - DCBS: N,N'-dicyclohexylbenzothiazole-2-sulfenamide; - MBS: N-oxydiethylenebenzothiazole-2-sulfenamide. NOTE Although MBTS is not a sulfenamide, it is the primary decomposition product of these accelerators and quantitatively determined by the method specified in 5.2. The analytical methods are applicable for most commercial sulfenamide accelerators: - sulfenamides of primary amines (type I); - sulfenamides of unhindered secondary amines (type II); - sulfenamides of hindered secondary amines (type III). The method (5.2) to determine purity by high performance liquid chromatography (HPLC) is the preferred method.
