Access to a wide range of plastic materials has been rationalized by the increased demand from growing populations and the development of high-throughput production systems. Plastic materials at low costs with reliable properties have been utilized in many everyday products. Multibillion-dollar companies are established around these plastic materials, and each polymer takes years to optimize, secure intellectual property, comply with the regulatory bodies such as the Registration, Evaluation, Authorisation and Restriction of Chemicals and the Environmental Protection Agency and develop consumer confidence. Therefore, developing a fully sustainable new plastic material with even a slightly different chemical structure is a costly and long process. Hence, the production of the common plastic materials with exactly the same chemical structures that does not require any new registration processes better reflects the reality of how to address the critical future of sustainable plastics. In this review, we have highlighted the very recent examples on the synthesis of common monomers using chemicals from sustainable feedstocks that can be used as a like-for-like substitute to prepare conventional petrochemical-free thermoplastics.

Cu-based catalysts with different metal compositions were synthesized. Among the binary catalysts, the Cu−ZnO catalyst showed good performance. The synergistic effect of Cu + and Cu 0 produced by reduction of copper species was an important in the hydrogenation of dimethyl adipate (DMA). The addition of the third component was conducive to improving the dispersion of Cu; therefore, the ternary catalyst with different components was further prepared. Results showed that the spatiotemporal yield of CZT-2.0 (4:2:1) at 250 °C was 9.0 g•g cat −1•h −1 , which may be related to the higher value of S Cu 0 and the larger dispersion of the Cu. The larger specific surface area of Cu 0 provides more H• active species, increasing the concentration of the H• active species and further promoting DMA hydrogenation. Moreover, the more basic surface of the CZT-2.0 catalyst will adsorb more DMA molecules and have more basic sites. From the HR-TEM results, the CZT-2.0 catalyst arranged in an ordered pore structure of hexagonal zinc ore.

“…Owing to the high potential of amines, in this communication, we investigated the sustainable conversion of biomass-derived 1,6-hexanediol (HDO) to amines aiming toward the production of high-performance sustainable polymers and chemicals . HDO is one of the key intermediates and can be obtained in high yield (>70%) from cellulose via the formation of 5-hydroxymethylfurfural and/or its derivatives − or levoglucosenone which is produced from sugars. Some heterogeneous catalysts, based on Ni, Ru, and Ce supported on metal oxides, have been successfully applied for HDO amination in the presence of NH 3 as an amine source (Table S1).…”

Efficient base-modulated product selectivity in the aqueous-phase Ru/C-catalyzed reductive amination of 1,6hexanediol (HDO) was reported by performing the reaction at mild conditions (463 K, 25 bar H 2 ). High selectivity of amines could be controlled by the addition of different bases; for example, Cs 2 CO 3 addition gave a high yield of 6-amino-1-hexanol (AH, 26%). However, the addition of Ba(OH) 2 resulted in the formation of high yield of secondary amination products, hexamethylenediamine (HMDA, 34%) and azepane (26%). The hydroxide base, especially Ba(OH) 2 , aids in the initial conversion of HDO to AH by significantly decreasing the apparent activation energy from 68 to 48 kJ mol −1 . A closer analysis of the formation of secondary products (azepane and HMDA) revealed a faster reaction between NH 3 and the carbonyl-containing intermediate by the addition of Ba(OH) 2 into the reaction solution.
