Abstract

An aqueous solution of basic mercaptide salt and water-soluble peroxide are mixed together in a reaction zone and maintained under reaction conditions effective to produce a vapor phase comprising organic disulfide, and concurrently vapor phase is recovered from the reaction zone. The process is highly efficient and enables production of organic disulfides in high yield and purity. Not only is the process very easy and simple to carry out, but in addition the process (i) eliminates the need for forming an organic phase of liquid organic disulfide product and conducting a separation between such product and the total aqueous phase used in the reaction, (ii) enables efficient control of a highly exothermic reaction, and (iii) minimizes alkanesulfonic acid salt formation during the reaction.
