هيدروژناسيون آلكيل لوولينات ها به گاما-والرولاكتون با فرميك اسيد در حضور كاتاليستهاي Nix%/MXene و بيوچار

In this research, hydrogen gas produced by formic acid decomposition in the presence of NiX%/MXene an‎d Biochar catalysts was used in the conversion reaction of ethyl levulinate to γ-valerolacton (GVL). In this research, various parameters such as temperature, time, amounts of catalyst, metal loaded on the catalyst surface, type an‎d amount of base, type of solvent, type of reactant, an‎d amount of formic acid were studied. Via the optimal condition for catalyst NiX%/MXene ( 30mg catalyst, 3mL of deionized water, 1.5g of sodium formate, 3mL of formic acid, 200°C temperature, an‎d a reaction time of 6 hours) an‎d for the Biochar catalyst ( 20mg catalyst, 3mL deionized water, 1.5 of sodium formate, 3mL of formic acid, 210°C temperature, an‎d a reaction time of 2 hours) the yields obtained for GVL are 94% an‎d 93% respectively. Various methods including XRD, FT-IR, EDX-MAP, ICP-MS, FE-SEM, an‎d BET were used for the purpose to confirm the synthesized catalyst. Also, the conformation to production of γ-valerolactone, GC-MS method was used.
