Class Information
Number: 585/721
Name: Chemistry of hydrocarbon compounds > Saturated compound synthesis > By condensation of a paraffin molecule with an olefin-acting molecule, e.g., alkylation, etc. > Using extraneous nonhydrocarbon agent
Description: Subject matter wherein part or all of the synthesis takes place in the presence of material containing an atom other than carbon and hydrogen, which chemically affects the synthesis by promoting, retarding, etc., 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.
