Catalytic Synthesis of n-Propyl Acetate with p-Toluene Sulfonic Acid

n-Propylacetate was synthesized from n—propyl and acetic acid in the presence of p—toluene sulfonic acid.The factors influencing the synthesis were investigated.The optimum conditions were found.The optimum conditions were as follows:molar ratio of n-propyl to acetic acid is 1.5 1,the mass ratio of the catalyst used to the reactants is 1.2%,the volume of cyclohexane as the water—carrying agent is 8mL,and the reaction time is 2 h. p—Toluene sulfonic acid is an excellent catalyst for synthesizing n—propyl acetate and the product yield can reach over 61.8%.
