The present invention is directed to a composition that contains polysulfides and that has a reduced odor level and to a method for reducing the odor of polysulfides. The composition contains a polysulfide and an inhibitor that reduces the odor level. The polysulfides include sulfurized olefins prepared by reacting the olefin with sulfur and H S in the presence of a catalyst. The inhibitors are selected from the group consisting of hydrocarbyl acrylates and hydrocarbyl methacrylates. The method for reducing the odor level of polysulfides involves contacting the polysulfide with an inhibitor selected from the group consisting of hydrocarbyl acrylates and hydrocarbyl methacrylates under conditions that reduce the odor level.

Invention relates to H,S scavengers polysulfide compounds and methods for scavenging H,S from polysulfide compounds. Furthermore, the invention uses a scavenger for selectively reducing the levels of hydrogen sulfide present in a polysulfide product.

H2S scavengers for polysulfide products and methods for scavenging H2S from polysulfide products

Formation of fouling deposits in a hydrocarbon process stream during processing at elevated temperatures is reduced by including in the hydrocarbon process stream an antifouling amount of a salt of a hydrocarbyl-substituted linked hydroxyaromatic compound, where the linked compound comprises at least two aromatic moieties.
