PROCESS FOR PRODUCING DIALLYL DISULFIDE

摘要

The invention provides a process for forming diallyl disulfide. The process comprises A) mixing together sulfur and at least one alkali metal sulfide in an initial aqueous medium in which at least about 90 volume percent of said aqueous medium is water, such that a disulfide source is formed in said initial aqueous medium thereby forming a disulfide source-conatining aqueous medium, and B) mixing together at least a portion of said disulfide source-containing aqueous medium and at lease one allyl halide selected from allyl cloride, allyl bromide, or a mixture of any two or all three of these, in the absence of any additional solvent other than water, at a temperature in the range of about 40°C to about 60°C, such that diallyl disulfide is formed.
