Abstract:
A system for carrying out microwave assisted chemistry, comprising:a source of microwave radiation;a cavity in communication with said source;an attenuator in communication with said cavity for providing access to said cavity while preventing microwaves from escaping through said attenuator; anda microwave-transparent, substantially cylindrical vessel vertically and removably positioned in said cavity and said attenuator and extending externally of said attenuator, said vessel capable of holding materials in said cavity while microwaves from said source are applied thereto;said vessel further comprising a reaction chamber and a venting portion;said reaction chamber being positioned entirely within said cavity;said venting portion being positioned adjacent to said reaction chamber, and extending from said cavity, and extending through said attenuator, and extending externally of said attenuator; andsaid venting portion further comprising a plurality of passageways extending longitudinally from said reaction chamber entirely through said venting portion, said passageways comprising an axial passageway for exhausting vapors and gases from said vessel and a parallel passageway for allowing ambient gases from sources external to said vessel to enter said reaction chamber below said axial passageway to thereby lift the vapors and gases and promote efficient evaporation of liquids.
