I. INTRODUCTION
In the field of chemical reactions, ethyl acetate saponification reaction is an important class of chemical reactions. Precise grasp of its performance in batch reactor is of key significance for improving reaction efficiency and optimizing product quality. Although previous studies have involved this reaction, there are still deficiencies in some details and performance analysis under specific conditions. This experiment aims to make up for these research gaps, in-depth analysis of the performance of ethyl acetate saponification batch reactor.

II. Experimental part
(i) Experimental material
1. ** Raw material **: High purity ethyl acetate and sodium hydroxide were selected as the reaction raw material to ensure that the interference of raw material quality on the experimental results was minimized.
2. ** Other reagents **: The auxiliary reagents involved in the experimental process, such as indicators used to detect the reaction process, etc., all use reagents that meet the experimental standards.

(ii) Experimental equipment
1. ** Batch reactor **: Customized batch reactor specially used for this experiment, which has good temperature control, stirring and sampling functions to meet the strict control of reaction conditions during the experimental process.
2. ** Detection instrument **: A high-precision conductivity meter is used to monitor the change of conductivity during the reaction process in real time, so as to characterize the reaction process; at the same time, it is equipped with a constant temperature device to ensure that the reaction temperature is constant.

(3) Experimental method
1. In the batch reactor, ethyl acetate and sodium hydroxide solution are added in a preset ratio, and the stirring device is turned on to quickly mix the reactants evenly.
2. The reaction temperature is set and maintained at a specific value using a constant temperature device, and the reaction start time is recorded.
3. During the reaction, the reaction solution was collected through the sampling port at regular intervals, and its conductivity was measured using a conductivity meter. According to the correlation between conductivity and reaction process, the degree of progress of the reaction was analyzed.

III. Experimental results and discussion
(I) Relationship between reaction process and conductivity
Experimental data show that with the progress of the reaction, the conductivity showed regular changes. In the early stage of the reaction, the conductivity was high due to the large amount of sodium hydroxide; as ethyl acetate reacted with sodium hydroxide to form sodium acetate and ethanol, the ion concentration in the solution changed, and the conductivity gradually decreased. By fitting the conductivity data, the quantitative relationship between the reaction process and conductivity can be accurately described.

(ii) Effect of temperature on reactor performance
Experiments were carried out under different temperature conditions, and it was found that the temperature increased, and the reaction rate was accelerated. This is because the temperature increased, the thermal movement of the molecules intensified, and the effective collision frequency between the reactant molecules increased, thus promoting the reaction. However, too high temperature may lead to the occurrence of side reactions and affect the purity of the product. The suitable temperature range of the reaction in this batch reactor was determined through experiments, which provided a reference for actual production.

(iii) Effect of reactant concentration on reactor performance
Experiments were carried out by changing the initial concentration of ethyl acetate and sodium hydroxide. The results showed that the concentration of the reactants increased, and the reaction rate increased. However, too high concentration may lead to uneven mixing and affect the reaction effect. Through the analysis of reaction data under different concentrations, the relationship between reactant concentration, reaction rate and product yield is obtained, which is helpful for rational allocation of reactant concentration in actual production.

IV. CONCLUSION
In this experiment, through the systematic study of the performance of ethyl acetate saponification batch reactor, the relationship between reaction process and conductivity, as well as the influence of temperature, reactant concentration and other factors on reactor performance are clarified. These results provide an important experimental basis for the application of ethyl acetate saponification reaction in industrial production, especially the optimal design and operation of batch reactor. Future research can be further extended to the study of reactor performance under more complex reaction conditions and multi-factor synergy on this basis.
