Abstract

The invention generally relates to systems and methods for increasing reaction yield. In certain embodiments, the invention provides systems for increasing a yield of a chemical reaction that include a pneumatic sprayer configured to generate a liquid spray discharge from a solvent. The solvent includes a plurality of molecules, a portion of which react with each other within the liquid spray discharge to form a reaction product. The system also includes a collector positioned to receive the liquid spray discharge including the unreacted molecules and the reaction product. The system also includes a recirculation loop connected from the collector to the pneumatic sprayer in order to allow the unreacted molecules and the reaction product to be recycled through the pneumatic sprayer, thereby allowing a plurality of the unreacted molecules to react with each other as the unreacted molecules cycle again through the system.

First claim

What is claimed is:

1. A system for increasing a yield of a chemical reaction, the system comprising:
a single pneumatic sprayer operably associated with a voltage source in order to generate a charged liquid spray discharge;
a collector comprising a single inlet, wherein the single inlet of the collector is operably associated with only the single pneumatic sprayer and is positioned to receive the liquid spray discharge, wherein the system is configured such that discharge from the single pneumatic sprayer passes directly from the single pneumatic sprayer to the collector without heating from a heater; and
a recirculation loop connected from the collector solely to the single pneumatic sprayer in order to allow the liquid spray discharge to be recycled solely through the pneumatic sprayer.

2. The system according to claim 1 wherein the collector comprises an electrostatic precipitator.

3. The system according to claim 2 , wherein the collector further comprises a liquid degassing unit within a vacuum chamber positioned after the electrostatic precipitator, thereby allowing gas from the pneumatic sprayer to be released from the system.

4. The system according to claim 3 , wherein the liquid degassing unit comprises a semi-permeable membrane within the vacuum chamber.

5. The system according to claim 3 , wherein the collector further comprises a condenser positioned after an outlet of the liquid degassing unit within the vacuum chamber.

6. The system according to claim 5 , wherein the condenser is a cryogenic condenser.

7. The system according to claim 5 , further comprising a mass spectrometer.

8. The system according to claim 1 , wherein the pneumatic sprayer is an electrosonic spray ionization source.

9. The system according to claim 1 , further comprising an elongate member between the pneumatic sprayer and the collector.

10. A system comprising:
a refrigerant apparatus comprising:
an inlet port;
a droplet forming region comprising a single spray generator operably associated with a voltage source to generate an electrospray plume; and
a condensing region that at a proximal end is only accessed via the inlet port that is operably associated with only the single spray generator, wherein the droplet forming region and the liquid condensing region are operably coupled to each other via tubing to form a circulating loop for flow such that a portion of reagents introduced via the inlet port react with each other in droplets formed in the droplet forming region to produce reaction product, which reaction product is condensed along with unreacted reagents in the condensing region and the reaction product and the unreacted reagents are re-circulated through only the single spray generator and the system one or more times, thereby allowing the unreacted reagents to react with each other as the unreacted reagents cycle again through the system.

11. The system according to claim 10 , wherein the droplet forming region comprises a flow regulating valve and an evaporator.

12. The system according to claim 11 , wherein the condensing region comprises a condenser.

13. The system according to claim 12 , further comprising a pump.

14. The system according to claim 13 , wherein the pump is a compressor, which is situated between the evaporator and the condenser.

15. The system according to claim 14 , wherein a portion of the tubing is transparent.

16. The system according to claim 14 , further comprising one or more pressure sensors.

17. The system according to claim 14 , further comprising an outlet port.

18. The system according to claim 17 , wherein the outlet port is coupled to an outlet tube that is operably associated with the voltage source in a manner such that the electrospray plume is generated at a distal end of the outlet tube.

19. The system according to claim 18 , further comprising a mass spectrometer, operably associated with the system to receive the spray generated at the distal end of the outlet tube.
