Significance and Use | ||||
The test method is designed to assess the purity of MBTS, which is used for rubber and latex vulcanization acceleration. The amount of MBTS is of importance in predicting performance in rubber compounds and for raw material purchase and control. This test method may be used as a quality control tool and for research and development work. |

1. Scope | ||||
1.1 This test method covers the determination of assay of benzothiazyl disulfide (MBTS). It is based on a titration of free iodine liberated upon reduction of MBTS, with potassium iodide (KI) in acid medium. 1.2 The assay is determined as mass percent. 1.3 Free 2-mercaptobenzothiazole (MBT) content is not determined. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
