The experimental set-up which includes a 330 ml stainless steel reactor with four baffles and a stainless steel cooling coil of six turns and a diameter 63 mm is as illustrated in Fig. 1. The inlet temperatures of the feed reactants and the reactor temperatures were measured with the help of a RTD probe. The rpm of the stirrer was checked at regular
intervals using a tachometer and the speed (rpm) was regulated by varying voltage to the stirrer motor. The constant temperature bath and the feed tubes were insulated with Plaster of Paris to minimize the heat losses. The reactants were allowed to flow through the coils in the bath and through the feed lines into the collection tank for sufficient
amount of time such that the reactants attained steady state feed temperatures. When feed temperatures had attained constant values,
the drain tube of the reactor was closed
