“…Biomass is the globally most abundant renewable feedstock with an annual natural production of ∼170 billion metric tons and is considered a promising source for the sustainable production of commodity chemicals, fuels, and polymers. − Moreover, the utilization of biomass is beneficial for the mitigation of net greenhouse gas emissions . Lignocellulose is the major component in abundant biomass resources, consisting mainly of polysaccharides (cellulose and hemicellulose) and phenolic compounds (lignin). , Cellulose (35–50%) is the main part of the overall residues and occurs together with the other components hemicellulose (20–35%) and lignin (10–25%). − Various methods based on hydrothermal, chemocatalytic, or biological enzymatic techniques are known for the depolymerization of polysaccharides to their primary constituents, e.g., glucose and xylose .…”

Synthesis of high-value-added chemicals from biomass and/or biomass-derived platform molecules is considered an important strategy to mitigate the global dependency on fossil resources and include renewable resources in a circular economy. In recent years, the synthesis of bio-based plastics has received significant attention as a potential alternative to conventional industrial processes. Thus, a lot of effort has been put into the development of not only different classes of biomonomers but also bio-based drop-in chemicals. Amine-derived molecules, especially alcohol-amines, diamines, and N-heterocyclic amines, are the most important classes of functional monomers for the production of polyamides, polyimides, polyurethanes, and polyureas. Additionally, these amines are extensively used in pharmaceuticals. In this review, we will give a concise overview of the up-to-date methods for the production of industrially important amines from biomass-derived oxygenates. Special attention will be given to the catalytic amination of biomass aldehyde- and alcohol-based oxygenates, reaction mechanism, catalyst stability, as well as their specific challenges and opportunities. We anticipate this critical and comprehensive review to provide detailed insights into the synthesis of bio-based amines and guide the development of effective greener synthetic methodologies.

The reductive amination of 1,6‐hexanediol with ammonia is one of the most promising green routes for synthesis of 1,6‐hexanediamine. Herein, we developed a phosphorous modified Ni catalyst of Ni‐P/Al2O3. It presented satisfactory improved selectivity to 1,6‐hexanediamine in the reductive amination of 1,6‐hexanediol compared to the Ni/Al2O3 catalyst. The phosphorous tended to interact with Al2O3 to form AlPOx species, induced Ni nanoparticle to be flatter, and the decrease of strong acid sites, the new‐formed Ni‐AlPOx‐Al2O3 interface and the flatter Ni nanoparticle were the key to switch the dominating product from hexamethyleneimine to 1,6‐hexanediamine. This work develops an efficient catalyst for production of 1,6‐hexanediamine from the reductive amination of 1,6‐hexanediol, and provides a point of view about designing selective non noble metal catalysts for producing primary diamines via reductive amination of diols.
