“…Sugarcane cropping usually occurs between April and November each year, which coincides with the dry season. Therefore, the influences of sugarcane were assessed for the analyzed period, since the sugarcane contained 40% glucose polymer cellulose, 30% hemicellulose, and 18% lignin as well as waxes, proteins, and other compounds (12%) (Sun et al, 2004;Ribeiro et al, 2012). The inclusion of lignin derivatives was greater in the dry season, a period that corresponded to the growth of sugarcane, which is widespread in the study are.…”

“…To deeply understand the amine content, the SCB and SCB-NH 2 were also analyzed by elemental analysis ( Table 1 ). Before the amination, the nitrogen element (N) content in SCB is only 0.19%, which is attributed to a minor amount of protein in the primary SCB [ 40 , 41 , 42 ]. After the amination, the N content increases to 1.98%, confirming the successful grafting of –NH 2 groups onto SCB.…”

A biomass-based catalyst with amine groups (–NH2), viz., amine-functionalized sugarcane bagasse (SCB-NH2), was prepared through the amination of sugarcane bagasse (SCB) in a two-step process. The physicochemical properties of the catalyst were characterized through FT-IR, elemental analysis, XRD, TG, and SEM-EDX techniques, which confirmed the –NH2 group was grafted onto SCB successfully. The catalytic performance of SCB-NH2 in Knoevenagel condensation reaction was tested in the batch and continuous flow reactions. Significantly, it was found that the catalytic performance of SCB-NH2 is better in flow system than that in batch system. Moreover, the SCB-NH2 presented an excellent catalytic activity and stability at the high flow rate. When the flow rate is at the 1.5 mL/min, no obvious deactivation was observed and the product yield and selectivity are more than 97% and 99% after 80 h of continuous reaction time, respectively. After the recovery of solvent from the resulting solution, a white solid was obtained as a target product. As a result, the SCB-NH2 is a promising catalyst for the synthesis of fine chemicals by Knoevenagel condensation reaction in large scale, and the modification of the renewable SCB with –NH2 group is a potential avenue for the preparation of amine-functionalized catalytic materials in industry.
