“…However, the catalyst recyclability was lower, achieving only 50% yield of GLV after the first cycle. Yi et al [121] carried out a comparative study using Ni and Ru catalyst, both supported on HZSM-H2 and using 1,4-dioxane as solvent. The catalytic experimental results showed that Ni/HZSM-5 catalyst achieved 93.1% yield of GVL, while Ru/HZSM-5 catalyst exhibited 85.7% yield of pentanoic esters (PE) and pentanoic acid (PA) under identical conditions (Fig.…”

In this review key processes for the synthesis of greener or more sustainable solvents derived from renewable sources (saccharides, lignocellulose and triglycerides) are discussed. It is shown that a series of platform chemicals such as glycerol, levulinic acid and furans can be converted into a variety of solvents through catalytic transformations that include hydrolysis, esterification, reduction and etherification reactions. It was also considered several aspects of each class of solvent regarding performance within the context of the reactions or extractions for which it is employed.

“…Furthermore, 5‐HMF in the presence of acidic or enzymatic catalysts can react with water to produce levulinic acid, currently seen as one of the most important renewable chemicals globally [60] . Levulinic acid has been used as an alternative fuel and as a reagent to produce chemicals such as γ‐valerolactone, succinic acid, butanone and 5‐nonanone [61–63] . In addition, methyl levulinate can be reacted with fatty alcohols in a reductive etherification process, in the presence of a Pd/C catalyst to synthesise biosurfactants and biolubricants [64] …”

This Review highlights the principal crops of Brazil and how their harvest waste can be used in the chemicals and materials industries. The Review covers various plants; with grains, fruits, trees and nuts all being discussed. Native and adopted plants are included and studies on using these plants as a source of chemicals and materials for industrial applications, polymer synthesis, medicinal use and in chemical research are discussed. The main aim of the Review is to highlight the principal Brazilian agricultural resources; such as sugarcane, oranges and soybean, as well as secondary resources, such as andiroba brazil nut, buriti and others, which should be explored further for scientific and technological applications. Furthermore, vegetable oils, carbohydrates (starch, cellulose, hemicellulose, lignocellulose and pectin), flavones and essential oils are described as well as their potential applications.

“…Among these products, LA is one of the 12 most important platform chemicals derived from biomass that have been announced by the U.S. Department of Energy, which exhibits excellent stability and has wide applications in organic synthesis, the pharmaceuticals industry, and agriculture ( Li et al, 2019 ). As the typical platform chemical is derived from biomass, LA can be converted to high added-value fuel additives such as γ-valerolactone ( Xu et al, 2019 ; Yi et al, 2020 ).…”

In this work, acid-catalyzed conversion of cellulose into levulinic acid in a biphasic solvent system was developed. Compared to a series of catalysts investigated in this study, the Amberlyst-15 as a more efficient acid catalyst was used in the hydrolysis of cellulose and further dehydration of derived intermediates into levulinic acid. Besides, the mechanism of biphasic solvent system in the conversion of cellulose was studied in detail, and the results showed biphasic solvent system can promote the conversion of cellulose and suppress the polymerization of the by-products (such as lactic acid).The reaction conditions, such as temperature, time, and catalyst loading were changed to investigate the effect on the yield of levulinic acid. The results indicated that an appealing LA yield of 59.24% was achieved at 200°C and 180 min with a 2:1 ratio of Amberlyst-15 catalyst and cellulose in GVL/H2O under N2 pressure. The influence of different amounts of NaCl addition to this reaction was also investigated. This study provides an economical and environmental-friendly method for the acid-catalyzed conversion of cellulose and high yield of the value-added chemical.
