General description
DL-Malic acid is mainly used as an acidulant in the food industry.
Application
- Tetra-Ln(3+)-Implanted Tellurotungstates Covalently Modified by dl-Malic Acid: Proton Conduction and Photochromic Properties.: This innovative study showcases dl-Malic acid as a key component in the synthesis of advanced tellurotungstates, contributing to notable enhancements in proton conduction and photochromic properties, which are critical for applications in smart materials and sensors (Niu et al., 2024).
- Direct regeneration of spent LiFePO(4) materials via a green and economical one-step hydrothermal process.: dl-Malic acid is utilized in a green chemistry approach for the direct regeneration of lithium iron phosphate (LiFePO4) materials, demonstrating a sustainable pathway for battery recycling and highlighting its importance in promoting environmental sustainability (Yang et al., 2023).
- Chitin Extracted from the Shell of Blue Swimming Crabs (Portunus pelagicus Linn.) Inhibits NF-kappaB p65 in Ethanol-Induced Gastric Ulcerative Wistar Rats.: In this research, dl-Malic acid serves as a catalyst in the extraction and functional activity testing of chitin, which is shown to have significant anti-inflammatory effects, suggesting its potential in pharmaceutical applications (Amelia et al., 2023).
- Manganese-Titanium Mixed Ion Sieves for the Selective Adsorption of Lithium Ions from an Artificial Salt Lake Brine.: Highlighting the application of dl-Malic acid in the synthesis of ion-exchange materials, this study points towards its utility in enhancing the selective adsorption properties of manganese-titanium mixed ion sieves, crucial for lithium recovery from brines (Ding et al., 2023).
