ABSTRACT:
In the production of high purity phenol, a water-phenol mixture recovered from the top of a distillation column is contacted with a water immiscible solvent to extract methyl benzofuran and other by-products and impurities in phenol production therefrom, with the extraction being accomplished at a temperature at which the water-phenol mixture is present as a single phase liquid. The remaining mixture of phenol and water is recycled to the distillation.
