PRESSURE SENSING REACTION VESSEL FOR MICROWAVE ASSISTED CHEMISTRY

摘要

A microwave vessel system for external and noninvasive pressure monitoring and control is disclosed. The system comprises a reaction vessel (21) formed of a material that is transparent to microwave radiation, with the reaction vessel (21) including a portion that is movable (22) under pressure generated by a chemical reaction inside the vessel while maintaining the reaction sealed inside the vessel. A sensor (30) is adjacent to the movable portion (22) of the vessel (21) for detecting the motion of the movable portion as the portion responds to pressure generated inside the vessel. The system includes means for maintaining the sensor (30) against the movable portion while microwaves are applied to the vessel (21) so that the movement of the movable portion (22) under pressure is detected by the sensor (30).
