Abstract:
An apparatus for carrying out wet chemical reactions under pressure comprising a pressure vessel (1) in which a reaction liquid (5) can be provided and which is adapted to be sealed in pressure fight manner by closure means (2, 3), characterized in that:a rinsing device is provided for rinsing the pressure vessel while removing the gaseous reaction products from the pressurized pressure vessel and while maintaining a predetermined pressure therein, said rinsing device comprising: a first gas conduit (12) for supplying pressurized gas to the pressure vessel (1), a second gas conduit (36) for venting gas between an interior of the pressure vessel (1) and an exterior of the pressure vessel (1), a first restrictor (14) disposed within said second gas conduit (36) to restrict the flow of venting gas through said second gas conduit (36), and a second restrictor (17) disposed within said first gas conduit (12) and immediately prior to the pressure vessel (1) to restrict a flow rate of the pressurized gas through said first gas conduit (12), said first and said second restrictors being correspondingly adjustable for maintaining consistent pressure within the pressure vessel (1), a vacuum tube (70) branching off said second gas conduit (36) prior to first restrictor (14) for selectively supplying a partial vacuum to the pressure vessel (1), and a reaction vessel (4) is provided within the pressure vessel (1) wherein gaseous reaction products can flow through said first restrictor (14) to an outlet (13).
