Determination of thiuram disulphides and analysis of thiuram disulphide-dithiocarbamate mixtures.
Potassium trithiocarbonate is used as reluctant for the titrimetric determination of thiuram disulphides in dimethylformamide-water media. The method is based on reductive cleavage of the disulphide linkage to yield the corresponding dithiocarbamates. In visual titrations, the end-point is marked by appearance of a yellow colour with the first drop of reagent added in excess. The method is simple, accurate, reliable and of wide applicability. It has been successfully extended to the analysis, in the same sample solution, of thiuram disulphide-dithiocarbamate mixtures.
