DEFINITION

Classification: 585/709

By condensation of a paraffin molecule with an olefin-acting molecule, e.g., alkylation, etc.:

(under subclass 700) Subject matter in which a paraffin molecule and an olefin molecule or the entire hydrocarbyl moiety of a nonhydrocarbon molecule are joined into a single molecule.

446+, for a process wherein an alkyl moiety is joined to an aromatic molecule.

502+, for a process wherein two or more unsaturated hydrocarbon molecules are joined.

708, for a process wherein a hydrocarbon molecule and part of the hydrocarbon moiety of another molecule are joined (alkyl transfer).
