Abstract
A process for alkylating an aromatic compound containing no hydroxyl groups comprising reacting at least one non-hydroxyl containing aromatic compound with at least one olefinic oligomer in the presence of an acidic ionic liquid catalyst, wherein the olefinic oligomer has a carbon range of from about C 12 to about C 70 and is synthesized by oligomerizing at least one monoolefin monomer in the presence of an acidic ionic liquid catalyst.
Claims
exact text as granted — not AI-modified1 - 22 . (canceled)
23 . A non-hydroxyl containing alkylated aromatic compound prepared by the process comprising reacting at least one non-hydroxyl containing aromatic compound with at least one olefinic oligomer in the presence of an acidic ionic liquid catalyst, wherein the olefinic oligomer has a carbon range of from about C 12 to about C 70 and is synthesized by oligomerizing at least one monoolefin monomer in the presence of an acidic ionic liquid catalyst.
24 . A non-hydroxyl containing alkylated aromatic compound wherein the alkyl substituent is derived from an olefinic oligomer having a carbon range of from about C 12 to C 70 and wherein the oligomer is prepared by oligomerizing at least one monoolefin monomer in the presence of an acidic ionic liquid catalyst.
25 . The non-hydroxyl containing alkylated aromatic compound according to claim 24 wherein the olefinic oligomer is selected from a propylene oligomer, a butene oligomer, an isobutylene oligomer, a pentene oligomer, an isopentene oligomer and mixtures thereof.
26 . The non-hydroxyl containing alkylated aromatic compound according to claim 25 , wherein the olefinic oligomer is a propylene oligomer.
