Method for continuously producing dimethyl disulfide
ActiveCN103864650ASolve recycling difficultiesGuaranteed conversionOrganic compound preparationHydropoly/poly sulfide preparationDiallyl disulfideMethyl disulfide
The invention discloses a method for continuously producing dimethyl disulfide. The method is characterized in that after being molten, a material sulfur is fed into a dimethyl trisulfide reactor by virtue of a feeding pump so as to react with recycled dimethyl disulfide to generate dimethyl trisulfide; dimethyl trisulfide and methyl mercaptan are feed into a dimethyl disulfide reactor so as to react to generate dimethyl disulfide; a dimethyl disulfide crude product is fed into a separating tank, so that most of hydrogen sulfide is separated out, a liquid-phase product is fed into a rectifying tower, a dimethyl disulfide product is condensed and recycled at a tower top, hydrogen sulfide is exhausted as a non-condensable gas, and the dimethyl disulfide and dimethyl trisulfide in a tower kettle are returned and recycled. A method of enabling dimethyl trisulfide to be excessive is adopted, so that methyl mercaptan is completely converted, separating requirements are lowered and a separating process is simplified, and therefore, not only can the dimethyl disulfide yield be improved to 90%, but also the product purity is up to 99wt%.
