Abstract

According to some aspects, described herein is an automated droplet-based reactor that utilizes oscillatory motion of a droplet in a tubular reactor under inert atmosphere. In some cases, such a reactor may address current shortcomings of continuous multi-phase flow platforms.

First claim

What is claimed is:

1. An oscillatory flow reactor comprising:
a sample port;
a carrier phase port; and
a tubing having a centerline running through a lumen of the tubing from a first end of the tubing to a second end of the tubing, the tubing being curved such that an imaginary straight line intersects with the centerline at least twice such that at least two portions of the tubing are aligned and observable with a single optical port.

2. The oscillatory flow reactor of claim 1 , wherein the imaginary straight line is substantially perpendicular to the centerline of the tubing.

3. The oscillatory flow reactor of claim 1 , further comprising:
a pressure source; and
one or more sensors aligned with the imaginary straight line which provide sample location feedback to the pressure source to control oscillatory motion of a sample based at least in part on sample location.

4. The oscillatory flow reactor of claim 3 , wherein the one or more sensors comprise one or more photodetectors.

5. The oscillatory flow reactor of claim 4 , further comprising a light source corresponding to each of the one or more photodetectors.

6. The oscillatory flow reactor of claim 1 , further comprising:
a heater adapted to heat contents in the tubing; and
a housing supporting the tubing and the heater.

7. The oscillatory flow reactor of claim 1 , wherein the tubing is horseshoe-shaped.

8. The oscillatory flow reactor of claim 1 , wherein the tubing is U-shaped.

9. The oscillatory flow reactor of claim 1 , wherein the tubing has an inner surface comprising a fluoropolymer.

10. The oscillatory flow reactor of claim 9 , wherein the fluoropolymer comprises at least one of FEP, PTFE or PFA.

11. The oscillatory flow reactor of claim 3 , wherein the one or more sensors comprises a first sensor positioned at one portion of the tubing and a second sensor positioned at another portion of the tubing, and the length along the tubing from the first sensor to the second sensor is greater than 1 cm and the distance from the first sensor to the second sensor is less than the length along the tubing from the first sensor to the second sensor.

12. A method of using an oscillatory flow reactor comprising:
injecting an aqueous droplet into a tubing, the tubing having an inner surface comprising a fluoropolymer;
injecting an organic substance droplet into the tubing; and
producing oscillatory flow of the aqueous droplet and the organic substance droplet through application of alternating pressure to the tubing, such that the aqueous droplet moves through the organic substance droplet with each oscillation,
wherein the oscillatory flow reactor further comprises:
a housing supporting the tubing;
a carrier phase port in fluid communication with the tubing; and
a sample port in fluid communication with the tubing.

13. The method of claim 12 , wherein the oscillatory flow reactor further comprises:
a pressure source; and
one or more sensors which provide sample location feedback to the pressure source to control oscillatory motion of a sample based at least in part on sample location.

14. The method of claim 12 , wherein the fluoropolymer comprises at least one of FEP, PTFE or PFA.

15. An oscillatory flow reactor comprising:
a tubing having an inner surface comprising a fluoropolymer, such that an aqueous droplet moves through an organic substance droplet in the tubing during application of alternating pressure to the tubing;
a housing supporting the tubing;
a carrier phase port in fluid communication with the tubing; and
a sample port in fluid communication with the tubing.

16. The oscillatory flow reactor of claim 15 , further comprising:
a pressure source; and
one or more sensors which provide sample location feedback to the pressure source to control oscillatory motion of a sample based at least in part on sample location.

17. The oscillatory flow reactor of claim 15 , wherein the tubing has a curved shape such that at least two portions of the tubing are aligned and observable with a single optical port.

18. The oscillatory flow reactor of claim 16 , wherein the one or more sensors comprises a first sensor positioned at one portion of the tubing and a second sensor positioned at another portion of the tubing, and the length along the tubing from the first sensor to the second sensor is greater than 1 cm.

19. The oscillatory flow reactor of claim 15 , wherein the fluoropolymer comprises at least one of FEP, PTFE or PFA.

20. The oscillatory flow reactor of claim 19 , wherein the fluoropolymer comprises FEP.
