The Ethyl acetate is a family organic compound of esters with high solvency power widely used in industrial paints and varnishes, but can also be used on substrates such as cellulosic film, paper, aluminum foil, PVC, polyester and polyethylene polypropylene. When this compound is reacted with a strong base, it is hydrolysed and this reaction is called saponification. The reaction is complex and not simple with several intermediate reactions, so it is necessary to study and know the kinetic methods which consist of analyzes of correlations based on kinetic data from experimental procedures. In this work we applied the differential method with the aim of finding a reaction order to satisfy the reaction conditions of the process. Three concentrations were used for Etlia acetate (0.1M, 0.04M and 0.08M) and the data collected from transient. The final concentration of the base used as reagent (Sodium Hydroxide) can be measured from conversion values calculated by the CEB-Armfield software. Based on these data, charts the concentration of sodium hydroxide versus time were plotted and the derivatives of the curves analyzes were calculated by linear regression enabling the calculation of the reaction order, however, it is important to note that the nonlinearity of the experimental data becomes linear regression only an approximation parameter. As regards the NaOH conversion verifies that the 0.1M concentrations for the experiment Ethyl acetate conversion was higher when compared with the other experiments. This fact occurs because there is no limiting reagent, causing the reactants to react effectively causing an increase in the conversion value.
