DEFINITION

Classification: 585/452

Attachment to side-chain, e.g., telomerization, etc.:

(under subclass 446) Subject matter wherein the process results in the addition of carbon atoms to the side-chain of a feed aromatic compound.

SEE OR SEARCH THIS CLASS, SUBCLASS:

438, for a similar process which produces an aromatic compound having an unsaturated side-chain, e.g., by condensation of toluene and butadiene, etc.

471+, in which this same result is accomplished by alkyl transfer.
