Title (EN) TEREPHTHALIC ACID COMPOSITION AND PROCESS FOR THE PRODUCTION THEREOF
(FR) COMPOSITION D'ACIDE TÉRÉPHTALIQUE ET SON PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN)Terephthalic acid is prepared by reacting a 2,5-furandicarboxylate with ethylene in the presence of a solvent to produce a bicyclic ether; and then dehydrating the bicyclic ether. The process of the present invention effectively produces terephthalic acid, while reducing or eliminating the impurities, color bodies and carbon oxides produced in commercial practice by the liquid-phase oxidation of methyl-substituted benzene feedstocks.
(FR)L'acide téréphtalique est préparé en faisant réagir un 2,5-furandicarboxylate avec de l'éthylène en présence d'un solvant afin de produire un éther bicyclique, puis en déshydratant l'éther bicyclique. Le procédé de la présente invention produit efficacement de l'acide téréphtalique, tout en réduisant ou en éliminant les impuretés, les corps colorés et les oxydes de carbone produits dans la pratique commerciale par l'oxydation en phase liquide de charges d'alimentation de benzène substitué par des méthyles.
