An integrated controlled catalytic oxidation process converts low value disulfide oil (DSO) compounds produced as a by-product of a generalized mercaptan oxidation (MEROX) process into oxidized DSO (ODSO) compounds including sulfoxides, sulfones, sulfonates and sulfinates that are completely or partially water soluble and which have utility, e.g., as lubricity additives in diesel fuel and as a solvent in aromatic solvent separation processes.

Oxidized disulfide oil (ODSO) solvent compositions are derived from by-product disulfide oil (DSO) compounds produced as by-products from the generalized mercaptan oxidation (MEROX) processing of a refinery feedstock. The oxidized disulfide oil (ODSO) solvent compositions comprise at least a primary oxidized disulfide oil (ODSO) compound selected from either water soluble or water insoluble oxidized disulfide oil (ODSO) compounds and in some embodiments at least 0.1 ppmw of a secondary oxidized disulfide oil (ODSO) compound that is a water soluble oxidized disulfide oil (ODSO) compound.
