Abstract

The Beckmann rearrangement of cyclohexanone oxime to ε- caprolactam in the presence of oleum proceeds in an ionic liquid, the caprolactamium hydrogen sulfate. We report its remarkable capability to keep the vapor pressure of dissolved sulfur trioxide below 10 kPa even at 140°C, allowing its safe use in large scale processes for a long-time. © 2009 American Chemical Society.
