Caprolactam is the precursor of many industrial chemical productions as in nylon industry, plastic industry, paint industry, lysine synthesis and cross-linking for polyurethanes. The production of caprolactam has been focus much from last three decades among the scientific community to fulfill the industrial need under environment precautions. Herein a sequential and explanatory review broadly covering the transformation of a different substrate as cyclohexanone oxime, cyclohexanone, cyclohexanol, cyclohexane, and biorenewable sources into caprolactam is presented. For every substrate, a wide range of catalyst including homogeneous as well as the heterogeneous system has been deeply considered. This study will be helpful for developing alternative industrial route for production of caprolactam.

己内酰胺是许多工业化学产品的前体，例如尼龙工业，塑料工业，油漆工业，赖氨酸合成和聚氨酯交联。在过去的三十年中，己内酰胺的生产一直是科学界关注的焦点，以在环境预防措施下满足工业需求。在本文中，进行了顺序和解释性综述，广泛涵盖了将不同底物如环己酮肟，环己酮，环己醇，环己烷和生物可再生来源转化为己内酰胺的过程。对于每种底物，已经广泛考虑了各种催化剂，包括均相系统和非均相系统。这项研究将有助于开发生产己内酰胺的替代工业路线。
