Renewable biomass-derived chemicals have received considerable interest as a potential substitute for petroleum-derived chemicals. Hexamethylenediamine is a key intermediate in manufacturing nylon 66, a synthetic polymer that is broadly used in society. This article reviews the catalytic production of hexamethylenediamine from biomass-derived chemical feedstocks, and specifically the bio-based routes for obtaining hexamethylenediamine. While methods to directly convert biomass to hexamethylenediamine have yet to be commercialized, the use of heterogeneous catalytic systems via combined processes appears to be a promising and emerging chemical pathway to achieve this goal. Current proposed routes for the renewable production of hexamethylenediamine are not yet entirely competitive with petrochemical production techniques, predominantly because of low efficiency and high cost. However, many opportunities exist to advance technologies that exploit renewable and bio-based feedstocks to generate hexamethylenediamine. Thus, the commercialization of biomass-derived nylon monomers appears achievable in the near future.

由可再生原料催化生产六亚甲基二胺

可再生生物质衍生的化学品作为石油衍生化学品的潜在替代品已引起了广泛的关注。六亚甲基二胺是制造尼龙66的关键中间体,尼龙66是一种在社会上广泛使用的合成聚合物。本文概述了从生物质衍生的化学原料中催化生产六亚甲基二胺,特别是从生物基途径获得六亚甲基二胺的方法。虽然将生物质直接转化为六亚甲基二胺的方法尚未实现商业化,但通过组合工艺使用多相催化体系似乎是实现该目标的有希望的新兴方法。目前提议的可再生生产六亚甲基二胺的途径与石化生产技术尚不完全竞争,主要是因为效率低和成本高。然而,存在许多机会来推进利用可再生和生物基原料产生六亚甲基二胺的技术。因此,在不久的将来似乎可以实现生物质衍生的尼龙单体的商业化。
