Title:, PROTIC SOLVENT IN A DEHYDROHALOGENATION PROCESS, THE PRODUCT OBTAINED THEREFROM AND LUBRICANT COMPOSITIONS CONTAINING SAME ABSTRACT, A process for producing a sulfurized olefin product substantially free of ash containing waste is disclosed. The process involves dehydrohalogenation of an olefin/ sulfur halide complex by contacting the complex with a protic solvent in the absence of any metal ion. The process allows for the solvolytic dehydrohalogenation of the complex. The sulfurized olefin product obtained is isolated and may be subjected to further processing to remove any remaining halides. The resulting sulfurized olefin is a useful additive in lubricating oils.
