Class Information
Number: 585/645
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > By alkyl transfer, e.g., disproportionation, etc. > Using organic extraneous agent
Description: Subject matter wherein a part or all of the synthesis takes place in the presence of an organic 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.
