摘要: This invention provides an improved process for the separation and recovery of byproducts associated with the isolation of C.sub.4 -C.sub.6 dicarboxylic acids contained in a waste byproduct stream derived from an adipic acid manufacturing operation involving nitric acid oxidation of a cyclohexanone/cyclohexanol feedstream.The main byproducts which are recovered are high purity dimethyl succinate, dimethyl glutarate and dimethyl adipate.

摘要: This invention provides a process for improving the recovery of byproducts associated with the isolation of C.sub.4 -C.sub.6 dicarboxylic acids contained in a waste byproduct stream, derived from an adipic acid manufacturing operation wherein there is involved nitric acid oxidation of a cyclohexanone/cyclohexanol feedstream.The main byproducts which are isolated are high purity dimethyl succinate, dimethyl glutarate and dimethyl adipate. Monomethyl esters of these dicarboxylic acids are recovered and recycled in the process.
