“…The catalyst managed to obtain levulinic acid conversions of up to 98% with a selectivity toward angelica lactone of 75%. 651 Many other catalysts that have been screened do not target angelica lactone in specific, and thus the corresponding yields of angelica lactone are lower, for example, the use of a Sn/Al zeolite beta catalyst to upscale furfural. The best performing catalyst system managed to convert 95% of the inputted furfural after 24 h, with the main products being furfuryl 2-butyl ether, levulinic acid, and angelica lactones with a selectivity of 29%, 14% and 23%, respectively.…”

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.

“…Following this concept, a lot of inspiring work was reported and later reviewed by Corrêa et al 143 for the progress and applications of the synthesis of angelica lactones. Recently, Thiripuranthagan et al 144 prepared Al-HZSM-5 loaded WO 3 catalysts (5% WO 3 /Al-HZSM-5) for the conversion of LevA to angelica lactone. 98% conversion of LevA and 74% selectivity of angelica lactone could be obtained under optimal conditions of 300 °C for 3 h. The fine dispersion of the acidic sites in the pore structure was considered to be responsible for the good catalytic performances.…”

“…The physicochemical properties of the catalyst support influence the performance of the liquid‐phase catalytic hydrogenation of FF. The mesoporous SBA‐15 (SB) material possesses an ordered hexagonal array of cylindrical channels, narrow pore‐size distribution, excellent hydrothermal stability, high surface area, and excellent physical structural properties [23–36] . Silica acts as the catalyst support and facilitates a high degree of dispersion of the metal atoms on its surface.…”

Furfuryl alcohol, which is the hydrogenated product of furfural, has been identified as a very promising platform chemical with high potential for applications in the manufacture of key chemicals, lubricants, fragrances, and pharmaceuticals. In this work, bare SB, and x % Ru/Al‐SB (x=1.5, 2.5, 3.5, and 4.5 wt. %) samples were fabricated by a hydrothermal method. Bare and most active catalysts were characterized by different techniques, such as BET, FE‐SEM, TEM, FT‐IR, and XRD, to understand their physical and chemical properties. An evaluation of the effects of various reaction parameters, such as catalyst loading, reaction temperature, and reaction time, on the catalytic performance, showed higher catalytic conversion of furfural and selectivity for the desired products. The most active RuS3 catalyst showed 100 % conversion of furfural and 99 % selectivity for furfuryl alcohol. It could be reused for five consecutive reaction cycles without significant loss of performance. In addition, Ru leaching and loss of conversion or selectivity were not noticed during the five‐run recycling test. The EDS elemental mapping analysis of the used catalyst established the preservation of the mesoporous structure, suggesting a strong interaction between the hexagonal porous silicate and the Ru nanoparticles.
