Abstract

N-cyclohexylaminobenzothiazole-2rsulphenamide (CBS) reacts with acetone at ambient temperature to give 2 (benzothiazolylthio propan-2-one (1) 1 l-bis-(2 -benzothiazolylthio)-2-cydohexylaminoprop-l-ene (2) cyclohexylamine and a trace of 2-mercaptobenzothiazole (MET). 1 is an intermediate in the production of 2 as it reacts with CBS in the absence of acetone to give 2. 1 3-bis-(2-benzothiazolylthio) propan-2-one (3) and 1 l-bis-(2-benzothiazolylthio) propan-2-one (4) are also produced in the latter reaction. This reactivity of sulphenamide accelerators should be borne in mind when employing acetone extraction in the analysis of curatives in rubber compounds or vulcanisates.
