Abstract

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.
