水热胺化Hydrothermal amination of biomass to nitrogenous chemicals
Recently, Profs. Hu Li (Guizhou University) and Zhen Fang, published a review (Critical review, 2021 Green Chemistry Hot Articles) paper in Green Chemistry about hydrothermal amination of biomass to nitrogenous chemicals.
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.
Conversion routes, processing strategies, state-of-the-art technical advances, challenges and perspectives in hydrothermal amination of N-rich biomass sources and N-free biomass feedstocks to nitrogenous chemicals.（水热胺化富氮和无氮生物质原料为含氮化学品的转化路线、加工策略、最新技术进展、挑战和前景。）.

水热胺化生物质制备含氮化合物
最近，国际学术期刊Green Chemistry以Critical review形式，发表了生物质水热胺化制备含氮化合物的综述。
生物质是生产高附加值含氮化合物最丰富、成本最低的可再生资源。然而，天然生物质和相关衍生物中存在大量水，通常需要在进行高值化过程之前将其去除。直接使用湿生物质和生物衍生物作为原料避免了干燥过程的能耗，在干燥过程中，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生产含氮化合物的一种有吸引力的技术策略。本文综述了将天然生物质、生物聚合物衍生物和含氮或不含氮的生物基平台分子水热胺化为有机氮化学品的最新技术。努力阐明生物质水热胺化的转化路线和经济/环境影响。并对生物质含氮化合物的大规模生产提出了挑战和展望。
