ASTM D4936

Description 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 (H 2 S) or 2-mercaptobenzothiazole 1 2 Any free amine (HNR 2) or weak acid salts of the corresponding amine (HX-HNR 2) are titrated prior to reduction
