DEFINITION

Classification: 987/234

Reaction products of at least one compound containing both P and S atoms with a hydrocarbon or the reaction product of a P and a S reactant with a hydrocarbon (reactant P and S can be in elemental or compound form) (9/04):

(under subclass 30) Subject matter wherein the product is the result of (a) reacting sulfur in elemental form or compound form with phosphorus in elemental or compound form and with a hydrocarbon reactant or (b) reacting a compound containing both sulfur and phosphorus atoms with a hydrocarbon reactant.

(1) Note. In (a) above, it is not necessary that all reactants be present at the same time. It is permissible to first react the hydrocarbon with either a phosphorus reactant and then in a subsequent step to react the product of that reaction with a sulfur containing reactant. Conversely, it is permissible to first react the hydrocarbon with a sulfur containing reactant and in a subsequent step react that product with a phosphorus containing reactant.

(2) Note. The products of this subclass are generally of unknown structure. If the product structure is known and is of a type provided higher in this class, then classification in that higher subclass is proper.
