So we redesign the new experiments to explore the effects brought by acid excess and alcohol excess. Then we analyzed the results in the various conditions, and we got a better ratio of acid and alcohol. In the final of the paper, we put forward more ways and tentative ideas in order to further improve the experiment Keywords n-butyl acetate forming material ratio improvements 乙酸正丁酯在工业上有着
