摘要
In an embodiment, a method of recovering an unreacted phenol from a bisphenol A production facility comprises reacting an initial phenol and an initial acetone in the presence of a catalyst to produce a bisphenol A stream comprising the unreacted phenol of the initial phenol and a bisphenol A, separating a purge stream comprising the unreacted phenol, and wherein the unreacted phenol is present in the purge stream in an amount of 60 to 90 wt%, based on the total weight of the purge stream; adding the purge stream to a phenol purification section of a phenol production facility; and forming a purified phenol outlet stream in the phenol purification section, wherein the purified phenol outlet stream comprises a total phenol concentration of greater than or equal to 99.5 wt% based on the total weight of the purified phenol outlet stream.
