 Page 1 ABSTRACT Two experiments were conducted for tubular flow reactor (TFR). The objectives for the first experiment is to examine the effect of a pulse input in tubular flow reactor and to construct a residence time distribution (RTD) function for the tubular reactor. The second objective for experiment 2 is to examine the effect of a step change input in tubular flow reactor and to construct a residence time distribution (RTD) function for the tubular flow reactor. The experiment is start first by taking the inlet and outlet conductivity. Then, the graph is plot and the C(t) is obtained before the E(t) curve can be plotted. From the E(t) curve, the area under graph is obtained. Based on that, calculation have been made to get the readings for mean residence time, second moment or variance and third moment or also known as skewness. From the graph of first experiment, it showed that the residence time distribution (RTD) for pulse input increased with time. After a few minutes, it will slowly decreases until the value of zero. While for the second experiment, it can be seen that the value slowly increase of outlet conductivity and E(t), the outlet conductivity reached constant at last. The mean residence time, second moment (Variance) and third moment (Skewness) were calculated was calculated from the graph. For the first experiment, the value of mean residence time is 1.4667 min, the second moment (Variance) is 0.4756 min 2 and the third moment (Skewness) is 0.3746 min. For the experiment 2, the mean residence time, the second moment (Variance) and third moment (Skewness) are 11.2060  min, -97.6774 min 2  and -68.6368 respectively. INTRODUCTION Tubular reactors are often used when continuous operation is required but without  back-mixing of products and reactants. The Tubular Reactor is specially designed to allow detailed study of this important process. Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product. This means that the inaccurate and inconvenient process of titration, which was formally used to monitor the reaction progress, is no longer necessar y. A cooling coil and immersion heater are provided inside the vessel to provide constant reaction temperature. The desired reaction temperature is achieved by controlling the heating using a digital temperature controller located on the front panel. Two non-corroding
