Class Information
Number: 585/718
Name: Chemistry of hydrocarbon compounds > Saturated compound synthesis > By condensation of a paraffin molecule with an olefin-acting molecule, e.g., alkylation, etc. > With coalescing or sorption of, or addition of specific agent to, effluent or effluent component
Description: Subject matter wherein the effluent from the alkylation reaction or a component thereof is treated, employing a chemical or physical phenomenon, to purify or separate the effluent or effluent component, the phenomenon being coalescence or sorption of with a solid sorbent, or requiring the addition of a material from outside the reaction mixture, e.g., a solvent, a reactant, a reaction inhibitor, etc.
