Understanding the role of designed solid acid sites in the low-temperature production of ϵ-Caprolactam

Understanding the role of designed solid acid sites in the low-temperature production of ϵ-Caprolactam
Modern society is placing increasing demands on commodity chemicals, driven by the ever-growing global population and the desire for improved standards of living. As the polymer industry grows, a sustainable route to ϵ-caprolactam, the precursor to the recyclable nylon-6 polymer, is becoming increasingly important. To this end, we have designed and characterized a recyclable SAPO catalyst using a range of characterization techniques, to achieve near quantitative yields of ϵ-caprolactam from cyclohexanone oxime. The catalytic process operates under significantly less energetically demanding conditions than other widely practiced industrial processes.

Abstract

Modern society is placing increasing demands on commodity chemicals, driven by the ever-growing global population and the desire for improved standards of living. As the polymer industry grows, a sustainable route to ϵ-caprolactam, the precursor to the recyclable nylon-6 polymer, is becoming increasingly important. To this end, we have designed and characterized a recyclable SAPO catalyst using a range of characterization techniques, to achieve near quantitative yields of ϵ-caprolactam from cyclohexanone oxime. The catalytic process operates under significantly less energetically demanding conditions than other widely practiced industrial processes.
