Class Information
Number: 508/419
Name: Solid anti-friction devices, materials therefor, lubricant or separant compositions for moving solid surfaces, and miscellaneous mineral oil compositions > Lubricants or separants for moving solid surfaces and miscellaneous mineral oil compositions (e.g., water containing, etc.) > Compound of indeterminate structure, prepared by reacting a compound having phosphorus single bonded directly to chalcogen by nonionic bonding and attached directly or indirectly to carbon by nonionic bonding (e.g., by reaction of phosphorus acids and esters, etc.)
Description: Compositions which contain a compound of indeterminate structure, said compound being prepared by the reaction of a compound wherein chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is single bonded directly to phosphorus by nonionic bonding, which phosphorus is attached directly or indirectly to carbon by nonionic bonding.
