الملخص

Knowledge of kinetic parameters is of extreme importance for thechemical engineer prior to design of chemical reactors. This researchfocuses on the study of the kinetics of the saponification reactionbetween sodium hydroxide and ethyl acetate in a batch reactor.To achieve this, the batch reactor available at the unit operationlaboratory (Department of Chemical Engineering, University ofKhartoum) had been repaired and modified to suit the experimentalprocedures. The maintenance of the reactor includes change of bearingand bushes. The modification was made on the motion transmission fromthe electric motor to the agitator and on the temperature control systemwhere a digital thermometer was used.Prior to the kinetic study, two methods were tried for the temperaturecontrol. The first method used an electric heater plus a cooling jacketaround the reactor but failed to precisely control the temperature. Thesecond method used consists of a water bath of controlled temperaturewhere the reactants are heated to the required temperature before theywere fed to the reactor which was also heated to the same temperatureusing the water jacket. This method was successful in achieving a tightcontrol of the temperature, thus ensuring isothermal conditions.The reactions kinetics was studied through initially studying causticsoda concentrations dependency using an excess of ethyl acetate whilemaintaining isothermal conditions .Then the concentration dependencyof ethyl acetate was evaluated using equal concentrations of reactantsbefore operating at various condition to evaluate the temperaturedependency.Analytical mathematical and computer methods were used to analyzethe experimental observations and data. The results obtained (ofevaluated kinetic parameters) showed, a clear agreement with the valuesviifrom literature. Improved numerical accuracy has been shown in somecases to result as the use of polynomial fit relative to finite differencemethod.It is recommended that future work focuses on fully automating thebatch reactor using appropriate hardware and software (Labview)components.
