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.
