IMPROVED PROCESS FOR PRODUCING ALKYLATED AROMATIC FLUIDS

摘要

Colorless, predominantly monoalkyl aromatic fluids useful as lubricants that exhibit improved thermal oxidative stability are produced by aromatics olefin alkylation using preferably large pore commercial zeolite catalyst that has been pretreated to lower moisture content, water-of-hydration content and absorbed-oxygen content before carrying out the alkylation reaction.
