ABSTRACT:
A process for the decontamination of the distillation refinement residue from the process of oxidizing cyclohexane to KA oil is provided. The process comprises washing the distillation refinement residue with the crystallization by-product obtained in crystallizing adipic acid from the product stream of the process of oxidizing the KA oil with a strong acid. This crystallization residue comprises residual amounts of the strong acid and adipic acid, as well as substantial amounts of glutaric acid and succinic acid.
