Class Information
Number: 585/486
Name: Chemistry of hydrocarbon compounds > Aromatic compound synthesis > By dealkylation > Using extraneous agent in reaction zone, e.g., catalyst, etc.
Description: Subject matter wherein part or all of the synthesis takes place in the presence of an added material, whether called a catalyst, a diluent, a heat carrier, etc., or not, which speeds a desired reaction or retards in undesired reaction and which does not supply a significant number of atoms of material to the final product.
