An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.

The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.

A method for producing ethylbenzene (EB) comprising introducing to an oxidative coupling of methane (OCM) reactor an OCM reactant mixture comprising CH.sub.4 and O.sub.2; allowing the OCM reactant mixture to react via OCM reaction to form an OCM product mixture comprising C.sub.2H.sub.4, C.sub.2H.sub.6, water, CO, CO.sub.2 and unreacted methane; separating the water and optionally CO and/or CO.sub.2 from the OCM product mixture to yield an EB reactant mixture comprising C.sub.2H.sub.4, C.sub.2H.sub.6, unreacted methane, and optionally CO and/or CO.sub.2; (d) introducing benzene and an EB reactant mixture to an EB reactor; allowing benzene to react in a liquid phase with the ethylene of the EB reactant mixture to form EB; recovering from the EB reactor an EB product mixture comprising EB and unreacted benzene, and an unreacted alkanes mixture comprising C.sub.2H.sub.6 and unreacted methane, and optionally CO and/or CO.sub.2; and optionally recycling the unreacted alkanes mixture to the OCM reactor.

A method for preparing 2-alkylanthracene includes the step of separating 2-alkylanthracene from a reaction product of anthracene alkylation reaction. The anthracene alkylation reaction is a reaction of anthracene and an alkylation reagent under an alkylation condition and in the presence of an alkylation reaction solvent and a catalyst. The reaction product of the anthracene alkylation reaction contains anthracene and the product of a series of alkylanthracenes containing 2-alkylanthracene.
