Abstract
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.
