Model phenolic compounds as well as coal-derived phenols were found to be readily etherified by reaction with 2-methyl-2-butene and an acid catalyst. The reaction is equilibrium limited with formation of ethers being favoured at low temperatures and high olefin concentrations. Various acids were employed and 40% H/sub 2/SO/sub 4/ in methanol was found to be superior to 40% H/sub 2/SO/sub 4/ in water, especially at high olefin concentrations. The acid/methanol solutions were also found to be quite useful for extraction of phenols from coal naphtha.
