Abstract

The present invention refers to an apparatus for carrying out wet chemical reactions under pressure comprising a pressure sure vessel in which a reaction liquid can be provided and which is adapted to be sealed in a pressure-tight manner by closure means. When the reaction liquid is heated, the pressure in the interior of the pressure vessel will increase; the stressability limit of the pressure vessel must, however, not be exceeded. The total pressure in the interior is composed of the partial pressures of the reaction liquid and of the reaction products. The reaction liquid must be maintained at so low a temperature that the sum of the partial pressures of the reaction liquid and of the gaseous reaction products does not exceed the maximum load value of the pressure vessel. For achieving a wet chemical reaction which is as fast and as efficient as possible, the highest possible temperature of the reaction liquid is, however, required. In accordance with the present invention these problems are solved by a rinsing device for rinsing the pressure vessel while removing gaseous reaction products from the pressurized pressure vessel and while maintaining a predetermined pressure therein. This has the effect that the gaseous reaction products are removed from the pressure vessel so that said gaseous reaction products will neither displace the reaction equilibrium nor influence the pressure conditions.
