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.

Abstract: Trithiane and phosphorus and/or thiophosphorus acid derivatives are described which are useful as extreme pressure compositions. The process comprises a reaction product obtained by reacting (A) an aldehyde of the structure wherein R is a hydrocarbyl group containing from 1 to about 18 carbon atoms with (B) a phosphorus acid of the structure (I) wherein R2 and R3 are each independently a hydrocarbyl group containing from 1 to about 30 carbon atoms, X1 and X2 are each independently oxygen or sulfur and n is independently zero or one in the presence of a lubricating base oil. A neutralizing agent, component (C), may be reacted with the phosphorus acid and/or thiophosphorus acid intermediate formed by the reaction of components (A) and (B).
