Abstract

An organic compound containing nitrogen, oxygen and sulphur and thought to be the dimethylamide of benzthiazole-2-sulphuric acid of the formula <FORM:0642618/IV (b)/1> is prepared by oxidizing 2-mercaptobenzthiazole or 2 : 21-dibenzthiazyl disulphide in the presence of dimethylamine, e.g. in an aqueous solution. The oxidizing agent may be sodium chlorite, sodium hypochlorite or hydrogen peroxide. The reaction mixture may be allowed to stand until the organic compound crystallizes. The product yields benzthiazole and dimethylamine when treated with hot dilute hydrochloric acid, and 2-hydroxybenzthiazole, o-aminothiophenol and dimethylamine when treated with dilute sodium hydroxide. Specification 452,044 is referred to.ALSO:An organic compound containing nitrogen, sulphur and oxygen, prepared as in Group IV (b) and thought to be the dimethylamine of benzthiazole-2-sulphinic acid of the formula <FORM:0642618/V/1> is used as accelerator in the vulcanization of natural or synthetic rubber, e.g. G.R.S. In examples: (5) a mixture comprising natural rubber, zinc oxide, sulphur, stearic acid and the above organic compound is vulcanized; (6) a mixture similar to (5) and containing in addition "Cosmobile" black and pine tar is vulcanized; (7) G.R.S. rubber is used in place of the natural rubber in (6) and is vulcanized. Specification 452,044, [Group IV], is referred to.
