应用
- Use of carboxymethyl cellulose as binder for the production of water-soluble catalysts.: Levulinic acid is used in conjunction with carboxymethyl cellulose to produce water-soluble catalysts. This application demonstrates the acid′s versatility in catalyst synthesis, enhancing the solubility and functionality of the resulting products (Paganelli et al., 2024).
- Nanocavity in hollow sandwiched catalysts as substrate regulator for boosting hydrodeoxygenation of biomass-derived carbonyl compounds.: This research explores the use of levulinic acid in biomass conversion processes. The study highlights the acid′s role in enhancing hydrodeoxygenation reactions, contributing to more efficient biofuel production (Zheng et al., 2024).
- Mechanism of CO(2) in promoting the hydrogenation of levulinic acid to γ-valerolactone catalyzed by RuCl(3) in aqueous solution.: This paper investigates the catalytic hydrogenation of levulinic acid to γ-valerolactone. The findings provide insights into the role of CO2 in enhancing reaction efficiency, offering valuable information for industrial applications (Min et al., 2024).
- Integrated biorefinery approach for utilization of wood waste into levulinic acid and 2-Phenylethanol production under mild treatment conditions.: This study presents a biorefinery approach to convert wood waste into valuable chemicals, including levulinic acid. The process demonstrates the potential for sustainable production of levulinic acid and its derivatives from renewable resources (Pachapur et al., 2024).
