摘要：<p>In one embodiment, this invention provides a process fox converting a dilute aqueous filtrate byproduct stream from adipic acid manufacture into a concentrated methanolic solution which does not solidify at ambient temperatures. In another embodiment, this invention provides an improved process for the separation and recovery of byproducts associated with the isolation of C4-C6 dicarboxylic acids contained in a waste byproduct stream derived from an adipic acid manufacturing operation involving nitric acid oxidation of a cyclohexanone/cyclohexanol feedstream in the presence of a catalyst.</p>
