Abstract: A continuous flow reactor without any moving parts to facilitate solid-liquid reaction without clogging is disclosed herein. It comprises plurality of identical cavities in series/sequence, each cavity being provided with: a pair of inlets at the top to allow entry of reactants into the reactor; an outlet at the bottom to allow the reactants to the next cavity for mixing; and a jacket covering around the cavities to provide heating or cooling effect as per the requirement. The outlet of the previous cavity is inclined at a suitable angle relative to the outlet of the next cavity to prevent clogging and facilitate efficient mixing of the reactants.
