|Publication Date:||1 October 2005|
|ICS Code (Organic nitrogen compounds):||71.080.30|
This test method covers the determination of assay on mercaptobenzothiazol
Any free amine (HNR(2)) or weak acid salts of the corresponding amine (HX·HNR(2)) are titrated prior to reduction. This titer is used to calculate percent basic impurity (as free amine) in the sample.
With the indicated modifications, this test method is applicable to all MBT sulfenamides, that is,
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
