Biomass is the most abundant and low-cost renewable source for the production of value-added nitrogen-containing compounds. However, a large amount of water exists in natural biomass and relevant bio-derivatives, which often need to be removed prior to conducting valorization processes. Direct use of wet biomass and bio-derivatives as feedstocks definitely avoids energy consumption of drying processes, in which water acts as a reactive medium and is friendly to the environment and reaction devices. Hydrothermal amination of wet biomass feedstocks is thus an attractive technical strategy for producing nitrogen-containing compounds. This review summarizes state-of-the-art technologies in hydrothermal amination of natural biomass, bio-polymeric derivatives, and bio-based platform molecules with or without nitrogenous species into organonitrogen chemicals. Efforts are made to shed light on conversion routes and economic/environmental impacts of biomass hydrothermal amination. Challenges and perspectives on the large-scale production of biomass-derived nitrogenous compounds are also put forward.

生物质水热胺化成含氮化学品

生物质是用于生产高附加值含氮化合物的最丰富且成本最低的可再生资源。然而,大量的水存在于天然生物质和相关的生物衍生物中,通常需要在进行增值过程之前将其去除。直接使用湿生物质和生物衍生物作为原料,绝对避免了干燥过程的能源消耗,其中水作为反应介质,对环境和反应装置友好。因此,湿生物质原料的水热胺化是一种用于生产含氮化合物的有吸引力的技术策略。这篇综述总结了天然生物质、生物聚合物衍生物水热胺化的最先进技术,将含或不含含氮物质的生物基平台分子转化为有机氮化学品。努力阐明生物质热液胺化的转化路线和经济/环境影响。还提出了大规模生产生物质衍生含氮化合物的挑战和前景。
