Quercus suber cork generates bioactive components, such as phenolic acids, terpenoids, and tannins, with excellent biol. properties, including antioxidant, anti-inflammatory, and antiaging activities. Aiming to design environmentally benign processes to eliminate, or reduce, the use of toxic chems., we propose the green extraction of bioactives from cork using natural deep eutectic solvents (NADES). Several deep eutectic mixtures were developed, through the mixture of natural compounds, namely, lactic acid, glycerol, ethylene glycol, sodium citrate, and sodium lactate, chosen according to their origin, toxicity, biocompatibility, polarity, and pH. The results revealed higher extraction yields when using NADES instead of harsh solvents like dioxane, with the extraction process governed by several phys.-chem. parameters, including pH, polarity, viscosity, and d., and also by the method of extraction Acidic NADES composed of lactic acid and glycerol, or sodium citrate, extracted a greater amount of aromatic compounds, terpenoids, and fatty acids and their derivatives More basic eutectic mixtures, composed of sodium lactate and a polyol (ethylene glycol or glycerol), extracted predominantly low mol. weight polar compounds The extracts range encompassed by the developed NADES, together with the associated nontoxicity, low price, and ease of preparation, establish these solvents as a green approach to extract high added-value compounds from cork. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Recommanded Product: 111-46-6).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 111-46-6
