Lignin functionalization in tunable green solventsRistovska, Marija (Avtor) Likozar, Blaž (Mentor) ligninDESfunctionalizationgreen solventsbiomassLignin is a biopolymer mainly present in wood and herbaceous biomass, and it is the most abundant source of aromatics on Earth. Currently, the main application is for energy purposes. However, lignin shows a high potential for the development of biomaterials to replace fossil-based materials. To reach this goal, the lignin requires modification functionalization processes to make it suitable for biomaterials production. This research will focus on the modification of target lignin using tunable green solvents Deep Eutectic Solvents (DES) allowing simplifying the process and making the process environmentally friendly. Functionalization reactions will be performed in mild conditions (atmospheric pressure and reaction temperature < 100 °C), and the functionalized lignin will be recovered using an antisolvent. The amount of recovered lignin will be determined, and the chemical structure of the lignin will be studied using the FTIR technique. The effect of the tunable green solvents on the functionalization of lignin will be evaluated.20242024-09-10 09:35:01Diplomsko delo/naloga161353VisID: 24205COBISS_ID: 215923203sl
