ABSTRACT:
Phenol feed to a steam distilling column, containing alpha-methylstyrene and mesityl oxide, is treated with a base, without acidification, and the heavy phenol product is acidified and distilled in a high purity column to recover high purity phenol as a sidestream and lighter components as overhead. Acidification after steam distilling, rather than prior to steam distilling, increases phenol recovery by reducing the overhead pasteurizing cut from the high purity column.
