The set up consists of a Reactor fitted in a constant temperature water bath. Before starting the reaction the reactor is charged with measured quantity of one reactant. From a feed tank another reactant is fed to the reactor. Peristaltic Pump is provided to measure the flow of Chemical. One stirrer is fitted for mixing the reactants in reactor and other is fitted in water bath to keep the uniform temperature throughout in the bath. The temperature of bath can be maintained from ambient to 70°C with the help of Digital Temperature indicator Cum Controller.
