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

September 30‚ 2012 Experiment 5‚ Preparation of Synthetic Banana Oil Introduction: This experiment prepares synthetic banana oil (isopentyl acetate) through the Fisher esterification method by combining isopentyl alcohol with acetic and sulfuric acid then heating the mixture under reflux for an hour. Esterification is a chemical reaction in which two reactants (an alcohol and an acid) form an ester as the reaction product. Observations and Data: When the sulfuric acid was combined

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore
