Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for the production of phenol, the method comprising: (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 comprises an ethyleneamine derivative, and wherein the neutralization composition is substantially free of amine compounds other than ethyleneamine derivatives, and wherein the ethyleneamine derivative is selected from the group consisting of: ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA) aminoethylpiperazine (AEP), tetraethylenepentamine (TEPA), and mixtures of two or more thereof, and wherein the ethyleneamine derivative is selected from the group further consisting of heavy polyamine X (HPA X), wherein HPA X is a complex mixture of linear, branched, and cyclic ethyleneamines having six or more nitrogen atoms per molecule and having a molecular weight of 275.
