Abstract
Phenols are etherified to products such as anisole by contacting said phenols with a low molecular weight alcohol or ether in the presence of an acid catalyst comprising a sulfated composite of one or more transition metal oxides on alumina. The process of this invention may be used to etherify, in situ, phenols present in synthetic fuel feedstocks, such as phenols present in naphthas derived from coal liquefaction. Preferred catalysts comprise oxides of tungsten, hafnium, and mixtures thereof on a high surface area gamma alumina support containing at least 2 wt. % sulfate ions.
