Latest Patents
Miele holds a patent for a method for the production of phenanthrenequinone. This invention improves the yield and purity of phenanthrenequinone during its production by oxidation of phenanthrene using chromic acid in a sulfuric acidic medium. The process involves preparing a dispersion made up of phenanthrene, alkali dichromate, and water at temperatures between 95°C and 100°C. The dispersion is then cooled to 80°C-85°C, and the oxidation reaction is carried out under cooling with a portion-wise addition of concentrated sulfuric acid within a temperature range of 80°C to 85°C. This method enhances both the efficiency and quality of the production process.
