The isomerization of an alkylated phenol composition that contains an ortho-alkyl substituted phenol component to isomerize and reduce the level of ortho-alkyl substituted phenol component therein can be accomplished by heating that composition in the presence of a catalytically effective amount of a solid acid catalyst to carry out such isomerization and reduction in the level of ortho-alkyl substituted phenol. Examples of suitable solid acid catalysts include H-form zeolites, supported sulfonic acids, and supported heteropoly acids. The resulting isomerized product can be subsequently phosphorylated.
