Abstract
A composition comprising polysulfides, wherein at least about 50 wt. % of the polysulfides are branched C20 to C60 polysulfides represented by general formula R15S1—[S]n—S2R16 wherein R15 and R16 are each independently a branched C10 to C30 alkyl group and wherein n is an integer from 1 to 10. A process of producing a polysulfides crude product comprising one or more branched C20 to C60 polysulfides comprising: (A) reacting a feedstock comprising one or more branched C10 to C30 mercaptans and sulfur in the presence of a catalyst and (B) collecting the polysulfides crude product.

A process of producing a polysulfides crude product comprising one or more branched C20 to C60 polysulfides comprising:
- (A) reacting a feedstock comprising one or more branched C10 to C30 mercaptans and sulfur in the presence of a catalyst and (B) collecting the polysulfides crude product.
A process of producing one or more branched C20 to C60 polysulfides comprising:
- (a) reacting hydrogen sulfide (H2S) and a feedstock comprising one or more branched C10 to C30 olefins in the presence of an initiating agent to produce a branched C10+ mercaptans crude composition;
- (b) recovering an intermediate reaction product comprising one or more branched C10 to C30 mercaptans from the branched C10+ mercaptans crude composition;
- (c) reacting sulfur and the intermediate reaction product comprising one or more branched C10 to C30 mercaptans in the presence of a catalyst;
- and
- (d) collecting a C20+ polysulfides crude product comprising the one or more branched C20 to C60 polysulfides.
