Class Information
Number: 585/658
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > By dehydrogenation > Using acceptor, e.g., hydrogen-exchange disproportionation, etc. > Elemental o or s acceptor with extraneous nonhydrocarbon agent, e.g., catalyst, etc.
Description: Subject matter wherein the removed hydrogen combines with free oxygen and part or all of the synthesis takes place in the presence of a material which chemically affects the synthesis by promoting, retarding, etc., but which does not form a part of the desired product and is, at least in theory, separable from the desired reaction products. The agent may be a catalyst, solvent, etc.
