Catalytic oxidation of carbohydrates, such as sorbose, is an important process in the chemical and biochemical industry. Sorbose, being a sugar, is widely used in the production of vitamins, sweet additives, and other food products. However, in order to effectively use sorbose in various chemical processes, its structure must be transformed, which can be achieved through catalytic oxidation. The features of catalytic oxidation of sorbose on heterogeneous catalysts include the selection of an appropriate catalyst, the reaction conditions (temperature, pressure, and solvent), and the mechanisms of interaction between the catalyst and the substrate. The aim of this work is to investigate the features of the catalytic oxidation of sorbitol on various heterogeneous catalysts, to analyze the reaction mechanisms and to evaluate the influence of various factors on the efficiency of the process. The consideration of these aspects will allow to gain a deeper understanding of the potential of sorbitol use in chemical processing and to develop new approaches to its catalytic transformation. In this work, two heterogeneous platinum catalysts known from the literature were used in the oxidation of sorbitol under equal reaction conditions. All samples were analyzed using HPLC. Selectivity with respect to 2-keto-l-gulonic acid was determined based on these analytical data.
