PROCESS FOR THE SEPARATION OF ADIPIC ACID FROM MIXTURES CONTAINING GLUTARIC ACIDS AND/OR SUCCINIC ACIDS

摘要

1. A process for isolating adipic acid from a mixture of adipic acid with glutaric acids and/or succinic acids, the glutaric acids and succinic acids being reacted with a nitrogen base at an elevated temperature to give glutarimides and succinimides which are removed by distillation, wherein a primary C1 -C6 -alkylamine is used as the nitrogen base.
