DEFINITION

Classification: 508/349

The organic compound is a phosphorus ester or an organic -S(=O)(=O)O- compound (e.g., phosphosulfurized petroleum mahogany sulfonates, etc.):

(under subclass 346) Compositions wherein the organic compound that is phosphosulfurized or phosphooxidized is a phosphorus ester or an organic -S(=O)(=O)O- compound.

(1) Note. A phosphorus ester is characterized by divalent chalcogen bonded to both phosphorus and carbon, wherein the carbon may be single bonded to any atom but may be multiple bonded only to additional carbon.

(2) Note. An organic -S(=O)(=O)O- compound is one wherein the-S(=O)(=O)O- group is attached directly or indirectly by nonionic bonding to carbon of an organic compound.

(3) Note. See Notes to the Class Definition for the definition of an organic compound.
