Bisphenol-A is purified in a process which comprises the following steps:
a) cooling a liquid mixture comprising bisphenol-A and water in a
bisphenol-A crystallizer to form bisphenol-A crystals in a liquid phase;
b) separating the bisphenol-A crystals from the liquid phase; c) dividing
at least a portion of the liquid phase into a bisphenol-rich organic
phase and a water-rich phase; d) feeding phenol and at least a portion of
the bisphenol-rich organic phase into a adduct crystallizer to form a
crystalline adduct of phenol and bisphenol-A in a mother liquor, and e)
separating the crystalline adduct from the mother liquor. Bisphenol-A of
high purity at a high yield is obtained.
