Determining the Characteristics of Sodium Benzoate (E211) Production Using Mathematical Method

Abstract: The productivity of a particular product is highly effective if we know the chemical kinetics. Determining chemical kinetics requires a fundamental knowledge of reactants ’ declining concentrations or the formation of product concentration. Concentration can be determined by double-linear extrapolation, using the conductivity measurement of strong electrolytes. This method is based on two linear sloped-lines from which the linear constants from different diagrams can be read: The first diagram represents linear time dependence regarding difference in conductivity 2) The second diagram represents linear difference in conductivity dependence regarding concentration. Determining the characteristics of sodium benzoate (E211) production by using double-linear extrapolation provides fast results for chemical kinetics. Sodium benzoate (NaC6H5CO2) is a preservative. It is produced by the neutralization of benzoic acid (C7H6O2) with sodium hydroxide (NaOH) in a stirred batch reactor under different room temperatures: NaOH + C7H6O2 NaC6H5CO2 + H2O The kinetic parameters and characteristics of sodium benzoate production (activation energy, reaction rate constant, rate order) were determined
