Design and testing of an ozonolysis reactor module with on-the-fly ozone degassing under flow conditions

Abstract

Ozonolysis is an attractive, efficient, and green means of introducing oxygen containing functionalities using only oxygen and electricity. Unfortunately, safety issues associated with the accumulation of dissolved ozone and potentially...

An Automated Computer‐Vision “Bubble‐Counting” Technique to Characterise CO2 Dissolution into an Acetonitrile Flow Stream in a Teflon AF‐2400 Tube‐in‐Tube Flow Device

“…In addition to the use of a simple gas burette, we have shown that visual ‘bubble counting’ approaches can be used to quantify this [8a] . Other, more recent, related examples of ‘bubble counting’ approaches have also been described by Cherkasov, Rebrov and co‐workers, [20a] by Gavriilidis and co‐workers, [14i] and by Riley and co‐workers [20b] . An interesting investigation of outgassing from flow streams in microfluidic devices, used to obtain phase diagrams from pressure‐volume‐temperature measurements, is described by Mostowfi and co‐workers [21] .…”

Efficient degassing and ppm-level oxygen monitoring flow chemistry system

“…16 Therefore, the Teflon AF-2400 polymer is a popular choice of material to introduce gases in tube-in-tube reactors. [17][18][19][20][21][22][23][24][25][26][27][28][29] Similarly, Teflon AF-2400 membrane reactors can also be used for the degassing of a solution, where the oxygen concentration is regulated by the vacuum level in the degassing chamber and the flow rate of the liquid. 30 In this paper, we present a flow chemistry-based automated setup for discovering optimal conditions (i.e.…”
