ABSTRACT Plug flow reactor (PFR) can be define as a tubular reactor where the feed is continuously introduced at one end and the products continuously removed from the other end [ CITATION Plu \l 1033 ]. Hence the purpose of this experiment is to study the effects of mean residence on conversion factor of saponification reaction when ethyl acetate and sodium hydroxide in plug flow reactor. This experiment was conducted by separating three different part based on the steps. Part one is to determine the calibration curve of conversion vs conductivity. Sodium hydroxide and sodium acetate was prepared to mix together and got the conductivity values. Different volume which means different conversion for 0% until 100% was used in order to get the calibration curve. For part two, 6L of 0.1M of ethyl-acetate and sodium hydroxide were prepared and put into the reactant tanks. Main switch was switched on and the temperature for water, reactor and reactant tanks were set at 35˚C. The dosing pump 1 and 2 were switched on and the flow rate was set 2L/hr. Stop watch was started as soon as the bubble in tube dissapearred. After the product came out from the reactor, the conductivity values were recorded for the product stream for every 2 minutes until it became steady or do not change over time. The experiment was repeated using different flow rates which was 4 and 6L/hr. Lastly, for part three, after the experiment was done, all the liquids need to be drained out in order to make sure that the reactor and the tubings are cleaned properly. Spillage was wiped off. In this experiment, the result shows that lesser the concentration, the lesser the collision kinetic between the particles to produce the saponification process between sodium hydroxide ad ethyl acetate. Moreover, the time that need for conductivity values became steady or do not change increase as the flow rate of the reactant became higher. Higher flow rate of reactant will cause the increasing of the conversion of the product. 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
