DEFINITION

Classification: 585/617

Using nonhydrocarbon acceptor:

(under subclass 616) Subject matter wherein the process employs a material which reacts with the hydrogen removed from a feed molecule thereby synthesizing a compound containing the removed hydrogen and different from the added material.

(1) Note. These processes sometimes use a solid acceptor material which, after it is no longer of satisfactory activity, may be regenerated. While this acceptor material may sometimes be called a catalyst it is distinguishable from a true catalyst by the stoichiometric proportions used and by the fact the hydrogen is removed from the process as a compound containing some or all of the atoms brought into the process by the acceptor.
