Abstract
Process for obtaining alkyl- and arylalkylthiosulfates in a water-organic solvent two-phase system by nucleophilic substitution of the halogen of an alkyl or arylalkyl halide by a thiosulfate ion, characterized by the fact that the substitution is effected in the presence of a phase transfer agent acting as a catalyst and used in catalytic proportions.
