CARBOXYLIC ACID PRODUCTION PROCESS EMPLOYING SOLVENT FROM ESTERIFICATION OF LIGNOCELLULOSIC MATERIAL

Methods for producing a carboxylic acid employing a solvent from esterif ication of lignocellulosic materials. An acid-containing composition from esterif ication of lignocellulosic materials can be employed in the oxidation of para-xylene to terephthalic acid. The acid-containing composition can co...

Zusammenfassung:	Methods for producing a carboxylic acid employing a solvent from esterif ication of lignocellulosic materials. An acid-containing composition from esterif ication of lignocellulosic materials can be employed in the oxidation of para-xylene to terephthalic acid. The acid-containing composition can comprise acetic acid, acetic anhydride, and one or more terpenes. L'invention porte sur des procédés qui permettent de produire un acide carboxylique à l'aide d'un solvant issu de l'estérification de matières lignocellulosiques. Selon l'invention, on peut utiliser une composition contenant un acide formée par l'estérification de matières cellulosiques pour oxyder du paraxylène en acide téréphtalique. La composition contenant un acide peut comprendre de l'acide acétique, de l'anhydride acétique et un ou plusieurs terpènes.
