Reaction Steps
2-methyl-4,5-trimethylene-4-isothiazolin-3-one (0.78 parts) and sodium tertiary butyl mercaptan (0.56 parts) were stirred together in methanol (10 parts by volume) at 20° to 25° C. for 1 hour. The reactants were then drowned out into distilled water (100 parts by volume) and the disulphide reaction product (1 part) which separated was filtered and dried. The disulphide melted at 153°-5° C.
