  • METHOD FOR FORMING AN AROMATIC DIACID AND/OR AN AROMATIC DIACID PRECURSOR FROM A POLYESTER-CONTAINING FEEDSTOCK
    Publication number: 20160326335
    Abstract: A method for forming an aromatic diacid and/or an aromatic diacid precursor from a polyester-containing feedstock. The method comprises contacting the polyester-containing feedstock with water or an alcohol to depolymerize the polyester and thereby form an aromatic diacid and/or an aromatic diacid precursor, wherein the polyester-containing feedstock comprises about 80 wt % or more polyester and about 1 wt % or more of at least one secondary material, and wherein the at least one secondary material is not polyester.

  • Oxidation of aromatic hydrocarbons using brominated anthracene promoters
    Publication number: 20050192459
    Abstract: Brominated anthracene is effectively used in a catalyst system as promoter for the catalytic oxidation of aromatic hydrocarbons in the production of aromatic carboxylic acids and results in reduced corrosion of process equipment and reduced formation of alkyl bromides while providing yield and quality comparable to that of conventional bromine promoters.
