    SUMMARY: The reactor test rig (RTR) experiment is purposely done to compare the performance of single stage CSTR‚ 3-stages CSTRs and PFR. The solutions that been used in this experiment is dilution of 0.1M of sodium hydroxide‚ NaOH and 0.1M of ethyl acetate‚ Et(Ac) to 60L. There are four common measures of reactor performance and the most important one is conversion. Then the speed is set to be at 300rpm and reading is taken every 5 minutes till the outlet conductivity remains constant. From the conductivity
