    • 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.
    • 在含有氧化铝上的一种或多种过渡金属氧化物的硫酸化复合材料的酸催化剂存在下,使酚与低分子量醇或醚接触,将苯酚醚化成产物如苯甲醚。 本发明的方法可用于醚化原位存在于合成燃料原料中的苯酚,例如存在于源自煤液化的石脑油中的酚类。 优选的催化剂包含钨,铪及其混合物的氧化物,其含有至少2wt。 %硫酸根离子。
