In a preferred embodiment of the invention, the benzene is separated from the phenol and other oxidation products and recycled with the addition at each recycle stage of a further small amount of the reaction promotor. This may be added as such or may be formed in situ by continuously ...
23. The process of claim 10, further comprising oxidizing the alkyl aromatic to form a compound selected from the group consisting of an alcohol, a ketone, an acid, and a phenol. Description: FIELD The present disclosure relates to processes for making olefin oligomers and alkyl benzenes in ...
It has been known heretofore that catalytic treatment of petroleum hydrocarbons under certain conditions will produce aromatic hydrocarbons from hydroaromatics and paraffins. The aromatic hydrocarbons thus produced range all the way from benzene thru the xylenes, higher alkylated benzenes, napthalene and ...
