Реферат: Propylene glycol can be produced from glycerol, which is a low-cost by-product in transesterification of triglycerides for biodiesel production. A number of valuable products that find application in the production of fine chemicals and pharmaceutics can be obtained through oxidation of 1,2-propylene glycol. The potential of the chromium terephthalate CrMIL-101 in the selective oxidation of propylene glycol under mild conditions (50-70°C) using tert-butyl hydroperoxide as oxidant was explored. The effects of reaction conditions (temperature, concentrations, solvent nature) on this reaction were evaluated. Hydroxyacetone was shown to be the predominant product. C-C cleavage, which is typical of PG oxidation, did not take place in the catalytic system studied. However, the oxidation products (for example, methyl glyoxal) could undergo non-oxidative transformations under the reaction conditions. Further work is in progress to clarify this matter.
