Abstract
Properties of phenol-containing hydrocarbonaceous streams are improved by first treating the stream with a C.sub.1 to C.sub.10 alcohol and an acid. If enough alcohol and acid are employed, two liquid phases are formed, an alcohol/acid phase and a hydrocarbonaceous phase. The alcohol/acid phase, which now contains phenols, can be separated and contacted with a C.sub.1 to C.sub.16 olefin or the olefin can be added in situ. In any case, oxygen-alkylation of the phenolic groups occurs.
