Abstract
A method is disclosed for carrying out microwave assisted chemical reactions. The method includes the steps of placing reactants in a microwave-transparent vessel, placing the vessel and its contents into a microwave cavity, applying microwave radiation within the cavity and to the vessel and its contents while concurrently externally cooling the vessel conductively.
Claims52
A method of carrying out microwave assisted chemical reactions, the method comprising:
- placing reactants in a microwave-transparent vessel;
- placing the vessel and its contents into a microwave cavity;
- and
- applying a continuous single mode of microwave radiation within the cavity and to the vessel and its contents while concurrently externally cooling the vessel.
A method of carrying out microwave assisted chemical reactions, the method comprising:
- placing reactants in a microwave-transparent pressure resistant vessel and sealing the vessel;
- placing the sealed vessel and its contents into a microwave cavity;
- applying microwave radiation continuously within the cavity and to the vessel and its contents;
- while monitoring the temperature of the vessel;
- and
- while concurrently externally cooling the sealed vessel and its contents.
A method of carrying out microwave assisted chemical reactions, the method comprising:
- placing reactants in a microwave-transparent vessel;
- placing the vessel and its contents into a microwave cavity;
- monitoring the temperature of the vessel or its contents;
- and
- applying a continuous single mode of microwave radiation within the cavity and to the vessel and its contents until the temperature reaches a desired setpoint;
- and
- concurrently externally cooling the vessel and its contents while applying the continuous microwave radiation to maintain the temperature substantially at the setpoint.
An instrument for carrying out microwave assisted chemical reactions, said instrument comprising:
- a microwave cavity;
- a microwave-transparent vessel in said cavity;
- a detector for monitoring the temperature of said vessel or its contents in said cavity;
- means for applying a continuous single mode of microwave radiation within said cavity and to said vessel and its contents until the temperature reaches a desired setpoint as measured by said detector;
- and
- means for concurrently externally cooling said vessel and its contents while applying the continuous microwave radiation;
- and
- means for maintaining the temperature substantially at the setpoint while applying the microwave radiation.
