Document Type and Number:
Japanese Patent JP2002088056
Kind Code:
A
Abstract:
To provide an oxidation method by which a vulcanization accelerator for rubbers can be obtained in high purity and in high yield, while controlling the production of a copper salt which is a by-product.
This oxidation method comprising catalytically oxidizing a raw material comprising a thiol compound or thiol salt including dithiocarbamic acid and its salts or a disulfide compound with oxygen in the presence of the water-soluble chelate compound of copper as a catalyst to produce dibenzothiazolyldisulfide, benzothiazolylsufenamide, thiuramdisulfide.
