A process is disclosed for reducing the concentration of o-ethylphenol in m,p-cresol by partially t-butylating a mixture of the above and equilibrating the resultant mixture to convert o-ethylphenol and its 6-t-butyl derivative to the thermodynamically most stable 4-t-butyl-o-ethylphenol. The resultant mixture may then be separated by fractional distillation to isolate m,p-cresol low in o-ethylphenol, optionally, the mono-t-butylated derivatives of m,p-cresol and leave behind the 4-t-butyl-o-ethylphenol, along with di-t-butylated derivatives of all the phenols.
