摘要： A process for the reduction of methylbenzofuran (MBF) impurities in phenol obtained from the decomposition product of cumene hydroperoxide requires treating the phenol to reduce the level of acetol, contacting the phenol containing a low level of acetol with an acid resin at sufficient temperature and residence time to reduce the level of MBF by conversion to higher boiling compounds, then distilling the phenol to separate phenol from higher boiling compounds. The phenol may be treated in known ways, such as by treatment with an amine, to reduce the level of acetol. The phenol containing a low level of acetol is contacted with a strong acid resin to reduce the level of MBF.
