Preparation of epsilon-caprolactam via Beckmann rearrangement of cyclohexanone oxime: A mild and recyclable process
A recyclable liquid phase process for preparation of epsilon-caprolactam via the Beckmann rearrangement of cyclohexanone oxime is developed by utilizing Lewis acidic ionic liquid as catalyst and a mixture of supercritical CO2 and chloroform as extractant.
