摘要：
Methods and apparatus for producing a carboxylic acid employing a solvent from esterification of lignocellulosic materials. An acid-containing composition from esterification 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.
