I'm planning on testing a A + B (both liquids but immiscible) reaction in flow mode in a tubular reactor. Batch tests show that with good mixing reaction takes approx. 10 mins residence time for complete conversion.

So far, so good. My catch is, how to get good mixing of the two liquids.

Anyone having experience with a system like this? What kind of static mixer did you use?

Or any other tricks?

Try a simple T-piece.

Plenty of Literature on mixing issues with flow systems.

Doubt a simple tee would work. Flow systems yes, but immiscible flow systems are a different beast right?

i.e. With a mixing tee the two fluids would mix and if the reaction was fast sure we succed but otherwise due to the density difference they will separate quite rapidly and due to the negligible interfacial area now down goes your reaction rate.

Unless you manage to keep remixing. And therin comes a static mixer etc, right?

Could you mix it by sonification? Like submerging the reaction "vessel" into the ultrasonic bath for example?
