ABSTRACT:
Phenol containing MBF impurity is distilled in the presence of water and an extraction solvent for MBF (preferably AMS and/or cumene) to recover a phenol bottoms having reduced impurities. The use of solvent permits a reduction in the amount of water used, which reduces the amount of phenol in the overhead, thereby lowering costs.
