Number: 585/520
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > By addition of entire unsaturated molecules, e.g., polymerization, etc. > Using extraneous nonhydrocarbon agent, e.g., catalyst, etc.
Description: Subject matter wherein part or all of the synthesis takes place in the presence of a material which chemically effects 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., and is inorganic or is an organic material containing other elements than carbon and hydrogen.
