| titleOfInvention | Preparation of thiuram disulphides |
| abstract | A continuous process for the nitrite oxidation of an alkali metal dialkyl dithiocarbamate to the corresponding tetraalkyl thiuram disulphide comprises continuously introducing into a reaction zone a dilute aqueous solution of a mineral acid, in an amount sufficient to maintain the pH of the reaction zone and of the effluent therefrom below 4, maintaining at least a portion of the reaction zone under conditions of intense agitation to provide an environment favouring oxidation of the alkali metal dialkyl dithiocarbamate to tetraalkyl thiuram disulphide without substantial byproduct formation, continuously introducing into the intensely agitated portion of the reaction zone a dilute aqueous solution containing the alkali metal dialkyl dithiocarbamate and a nitrite oxidant, and withdrawing from the reaction zone an effluent containing the tetralkyl thiuram disulphide product. Molecular oxygen may be introduced continuously into the reaction zone. Examples describe the production of tetramethyl thiuram disulphide from sodium dimethyl dithiocarbamate. |
