Abstract: Calix［4］arene Sulfonic Acid Sodium was used as a non homogenous catalyst for synthesis of nButyl acetate using acetic acid and nbutyl alcohol as raw materials. The effects of reaction conditions, such as the quantity of catalyst, the ratio of the reactants and reaction time were discussed respectively. The product was characterized by index of refraction. The suitable conditions for the reaction were as follows: acetic acid 0.1 mol, molar ratio of nbutyl alcohol to acetic acid 1.2, catalyst amout 1 g, reaction time 4 h, the yield of nbutyl acetate can reach 81.41%. The catalyst could be used repeatedly keeping its initial activity. 
