DEFINITION

Classification: 585/446

By condensation of entire molecules or entire hydrocarbyl moieties thereof, e.g., alkylation, etc.:

(under subclass 400) Subject matter wherein there is added to an aromatic hydrocarbon, or that moiety of an aromatic nonhydrocarbon which remains after atoms other than carbon and hydrogen have been removed, an acyclic straight or branched hydrocarbon molecule or that moiety of an acyclic nonhydrocarbon which remains after atoms other than carbon and hydrogen have been removed.

(1) Note. The ring compound onto which the chain is introduced may already include one or more side-chains, e.g., toluene, xylene, etc.

470+, for a process in which a hydrocarbyl moiety which is only a part of a hydrocarbon molecule is added to an aromatic molecule.

709+, for alkylation of an olefin to produce a noncyclic hydrocarbon.
