DEFINITION

Classification: 508/419

Compound of indeterminate structure, prepared by reacting a compound having phos-phorus 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.):

(under subclass 110) 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.
