説明

Tosylated cotton fabrics were treated with thiourea in various solvents followed by alkaline hydrolysis to give products containing both mercaptan and disulfide residues. The substitution reaction proceeded more slowly than with potassium thiotacetate and faster than with sodium thiosulfate. The effect of the solvent on the reaction rate was found to be in the following order; water>dimethylformamide>methanol>dimethylsulfoxide. The conversion of mercaptan to disulfide in the hydrolysis product became greater with increasing tosyloxy conversion, regardless of the solvent used for the treatment with thiourea.
