DEFINITION

Classification: 508/325

Phosphorus or an inorganic phosphorus compound is reacted with the organic compound either together with or subsequent to the sulfurizing agent (e.g., terpene-sulfur-phosphorus sulfide reaction products, reaction product of sulfurized olefin with phosphorus sulfide, etc.):

(under subclass 322) Compositions wherein the organic compound is also reacted with phosphorus or an inorganic phosphorus compound, either simultaneously with or subsequent to sulfurization via elemental sulfur, sulfur halide, or metal polysulfide.
