| abstract | The condensation products of such accelerators as mercapto benzothiazole, dithiocarbamates or their analogues with aliphatic radicals substituted by an aromatic nucleus and carrying a reactive halogen in the aliphatic chain are used as vulcanization accelerators. The term analogues is defined as meaning compounds containing the grouping CSSX, where X represents hydrogen or the equivalent weight of a metal or complex radical such as a substituted ammonia or ammonium. In examples, (1) diethylammonium diethyldithiocarbamate is heated with alcoholic potash until all the diethylamine is evolved, p-nitrobenzyl chloride added and the mixture boiled under a reflux when a red oil separates out and is purified. (2) Mercaptobenzothiazole is reacted with p-nitrobenzyl chloride to give p-nitro-benzylthiobenzthiazole. (3) Mercaptobenzothiazole is reacted with benzyl chloride to give benzylthiobenzthiazole, and (4) dipiperidinodithiocarbamate is reacted with benzyl chloride. Specification 340,083 is referred to.ALSO:The condensation products of such accelerators as mercapto benzothiazole and dithiocarbamates and their analogues with aliphatic radicals substituted with an aromatic nucleus and carrying a reactive halogen in the aliphatic chain are used as vulcanization accelerators. The term analogues is defined as meaning compounds containing the grouping CSSX where X represents hydrogen or the equivalent weight of a metal or complex radical such as a substituted ammonia or ammonium. In examples (1) diethylammonium diethyldithiocarbamate is heated with an alcoholic solution of potassium hydroxide until the diethylamine is completely evolved, the alcoholic solution being then mixed with a hot solution of para-nitrobenzoyl chloride and boiled under a reflux when a red oil separates out and is purified. (2) mercaptobenzothiazole is reacted with para-nitrobenzyl chloride to give para-nitro-1-benzyl-thiobenzthiazole. (3) mercaptobenzothiazole is reacted with benzyl chloride to give benzylbenzthiazole sulphide (1-benzyl-thiobenzthiazole) and (4) piperidine piperidine-1-carbothionolate is reacted with benzyl chloride. Specification 340,083 is referred to. |
