<p>A system for carrying out microwave assisted chemical reactions is disclosed. The system includes a source of microwave radiation (11); a cavity (12) in communication with the source (11), an attenuator (13) in communication with the cavity (12) for providing access to the cavity while preventing microwaves from escaping through the attenuator (13), and a vessel (16) positioned in the cavity (12) and the attenuator (13) and extending externally of the attenuator for holding materials in the cavity while microwaves from the source are applied thereto. The vessel (16) includes a reaction chamber (23) and a venting portion (22). The chamber (23) portion is positioned entirely within the cavity (12), and the venting portion (22) extends from the cavity (12) and through the attenuator (13) and externally of the attenuator and has a gas passage (24) for permitting gases to flow to or from the reaction portion from gas sources external to the cavity, the attenuator, and the vessel.</p> |
