Abstract
2-Mercaptobenzthiazole, its homologues or substitution products are subjected in dry powdered form to oxidation by a gaseous mixture containing oxygen and nitrous gases to give the corresponding disulphides. As the oxygen-containing gas air may be used and other gases which do not interfere with the reaction may be present. In examples 2-mercaptobenzthiazole and 6-methyl-2-mercaptobenzthiazole in the form of fine powders are treated at 18--25 DEG C. with a mixture of cold air and nitrous gases such as are obtained by burning ammonia; the disulphides are formed quantitatively.
