DEFINITION

Classification: 585/251

With subsequent diverse conversion:

(under subclass 250) Subject matter in which a synthesis operation, different from hydrogenation of an unsaturated bond is performed upon the hydrogenated feedstock.

(1) Note. The subsequent conversion must be more than the mere treatment of an unwanted by-product to make such by-product equivalent to the feedstock to the original hydrogenation.
