Latest Patents
One of Hans Kratzer's latest patents involves the production of 3,3-dimethyl-2-oxo-butyric acid salt. This process includes the production of dichloropinacolone by introducing twice the molar amount of chlorine into pinacolone. The exothermic reaction mass is initially cooled to maintain a temperature below about 50°C until 60 to 80% of the chlorine has been introduced. After this, the reaction mass is heated above 50°C while the remainder of the chlorine is added, ensuring that the dichloropinacolone content reaches at least 97%. The molten product is then combined with an aqueous solution of an alkali, which is maintained at a temperature of at least 50°C. The alkali is present in more than three times the molar amount of the dichloropinacolone. Following this, potassium permanganate is added to the resulting solution, leading to the precipitation of solid MnO2, which is separated from the substantially pure dissolved salt of 3,3-dimethyl-2-oxo-butyric acid. This product is recognized as a compound suitable for further syntheses.
