METHOD OF SYNTHESIS OF SULFOXIDES Russian patent published in 1999 - IPC

Abstract RU 2127258 C1

FIELD: chemical technology. SUBSTANCE: method involves oxidation of sulfide with chlorine dioxide in an organic solvent at volume ratio sulfide : solvent = 1:(1-20) and molar ratio sulfide : chlorine dioxide = 1:0.5 for 2 h at 18-20 C. The yield of sulfoxide is 90% in dichloromethane medium. Synthesized sulfoxides can be used as extractants of metals, flotation agents and biologically active substances. EFFECT: improved method of synthesis. 1 cl
