Abstract
A pressure reactor which avoids leakage and prevents sample loss upon depressurization. Leakage is avoided by providing a reaction vessel with a screw-threaded closure member. Loss of sample is prevented by the provision of a vapor trap which collects any liquid or vapor which may include dissolved sample, from escaping upon disassembly i.e. de-pressurization of the reactor. A novel solvent system for use in conjunction with the reactor is also disclosed.
Claims4
In an apparatus for dissolving a difficultly soluble substance under pressure, said apparatus comprising an outer casing, a close-fitting reaction vessel adapted to be received within said outer casing, a first closure member for said reaction vessel, and a second closure member for said casing to prevent the first closure member from becoming unseated when the reaction vessel is pressurized,
- the improvement comprising a vapor trap for collecting and retaining reactants which tend to escape from the reaction vessel upon de-pressurization of the apparatus, wherein said first closure member includes an opening, an external diaphragm member to close said opening and a pressure relief plug which when positioned in said opening, together with said diaphragm member, defines said vapor trap.
