Class Information
Number: 585/714
Name: Chemistry of hydrocarbon compounds > Saturated compound synthesis > By condensation of a paraffin molecule with an olefin-acting molecule, e.g., alkylation, etc. > With introduction of same material at more than two serially spaced points of reaction zone system
Description: Subject matter wherein a feedstream of material, e.g., a catalyst, feedstock, recycle material, etc., which can be considered as coming directly from the same source, that is, having the same composition, is introduced to an alkylation reaction zone system at more than two points spaced along the flow path of the reactant material.
