The use of ultrasound techniques in flow
In recent work we describe the efficient and easily scalable transformation for converting alcohols and aldehydes to carboxylic acids and nitroalkane derivatives to the corresponding carbonyls and carboxylic acids using potassium permanganate as the oxidant within a continuous flow reactor [1]. Notably, the downstream processing of precipitated manganese dioxide in this application required the use of ultrasonics to ensure an even flow pattern and avoid fouling and blocking of the system.
