    摘要: The present invention provides an efficient dimethyl sulfoxide (DMSO) production process improved in the conversion from dimethyl sulfide (DMS) to DMSO by recycling the NOx used as a catalyst in the continuous oxidation reaction of DMS for producing DMSO, specifically providing a DMSO production process improved in the recovery rate and/or absorption rate of NOx by recovering NOx from the reaction off gas and/or the gas removed from the reaction product solution for re-utilization.
