Nitric Acid Oxidation of 2,4: 3,5-Dimethylene-D-gluconic Acid; Some Derivatives of 2,4-Methylene-D-glucarolactone-3,6

Pt catalysts for efficient aerobic oxidation of glucose to glucaric acid in water

“…[25][26][27] These reactions generate a significant amount of toxic by-products, thus making the process less sustainable and environmentally benign. The homogeneous catalyzed oxidation of glucose with HNO 3 , nitroxide, and NaNO 2 has also been reported 26,[28][29][30][31] in the range of 5 to 80 °C, yielding <50% glucaric acid. Besides the usage of corrosive and hazardous reagents, separation and recyclability of homogeneous catalysts from the products are a challenge.…”

Exceptional performance of bimetallic Pt1Cu3/TiO2 nanocatalysts for oxidation of gluconic acid and glucose with O2 to glucaric acid

“…Glucaric acid synthesis is the key step in this process. The current methods of glucaric acid synthesis involve either electrochemical or stoichiometric oxidation using undesirable reagents such as NaBr, NaOCl, mineral acids, and bleaches [3][4][5][6][7][8][9][10]. High concentrations of these oxidants in the reaction medium and generation of significant amounts of toxic by-products and inorganic salts are the major issues confronting the sustainability and environmental compatibility of these current routes.…”

Glucaric Acid Production from Miscanthus sacchariflorus via TEMPO-Mediated Oxidation with an Efficient Separation System

“…Meanwhile, the solubility of glucaric acid was influenced by its countercation. Among them, potassium salts decrease the solubility of glucaric acid in water; specifically, the glucaric acid monopotassium salt showed lower solubility in water . Based on the difference of solubility, glucaric acid could be easily separated when the cation of the reaction was changed from sodium to potassium.…”

“…A conventional method for obtaining glucaric acid from glucose is the concentrated nitric acid oxidation method. 5 However, the use of corrosive chemicals and the catalyst recycling requirements of this method have hindered its further application. To overcome these limitations, heterogeneous catalysts have been adopted for the oxidation of glucose to glucaric acid.…”

“…Glucaric acid can be obtained through the oxidation of glucose, and there are several studies that have reported the oxidation of glucose to glucaric acid. A conventional method for obtaining glucaric acid from glucose is the concentrated nitric acid oxidation method . However, the use of corrosive chemicals and the catalyst recycling requirements of this method have hindered its further application.…”
