Abstract:
An improved method for the production of phenol. The method comprises (a) synthesizing phenol through a process that utilizes an acidic catalyst; (b) neutralizing the acidic catalyst after substantial completion of step (a) by addition thereto of a neutralization composition, wherein the neutralization composition contains an ethyleneamine derivative.
