DEFINITION

Classification: 585/332

And preliminary isomerization or polymerization:

(under subclass 331) Subject matter wherein a material undergoing the alkylation synthesis has undergone a reaction wherein a feedstock is converted to another material having the same empirical formula but a different structural configuration, or in which an olefin has been condensed with one or more other olefin molecules.
