ASTM D4936-10(2019) 巯基苯并噻唑亚磺酰胺通过还原/滴定法测定的标准测试方法

1.1 This test method covers the determination of assay on mercaptobenzothiazole (MBT) sulfenamides. It is based on a titration of the basic amines liberated upon reduction of the sulfenamides with hydrogen sulfide gas (H2S)2,3 or 2-mercaptobenzothiazole. 1.2 Any free amine (HNR2) or weak acid salts of the corresponding amine (HX·HNR2) are titrated prior to reduction. This titer is used to calculate percent basic impurity (as free amine) in the sample. 1.3 With the indicated modifications, this test method is applicable to all MBT sulfenamides, that is, N-cyclohexyl-2benzothiazolesulfenamide (CBS), N,N-diisopropyl-2benzothiazyl sulfenamide (DIBS), 2 (morpholinothio) benzothiazole (MBS), N,N-dicylohexyl-2-benzothiazyl sulfenamide (DCBS), N-tert-butyl-benzothiazole-sulfenamide (TBBS), and 4-morpholinyl-2-benzothiazyl disulfide (MBSS). 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
