Abstract

1. A process for the production of benzothiazolesulfenamides from mercaptobenzothiazole or its salts and primary amines by oxidation in aqueous medium and filtration, characterized in that the oxidation is carried out to a conversion of the mercaptobenzothiazole or its salts of at most 95%.
