Title: Synthesis of n-butyl acetate catalyzed by palygorskite supported 12-tungstophosphotungstic acid
Abstract: Palygorskite supported 12-phosphotungstic acid is prepared by reflux and evaporation of the water mixture of acid activated palygorskite.It is characterized by IR and XRD spectroscopy.It is applied as catalyst in the n-butyl acetate synthesis.The orthogonal experiment shows that the esterification yield is 99.8% and the selectivity is nearly 100% under the conditions:the molar ratio of n-butanol to acetic acid is 1∶1.2,the weight of catalyst is 1.7% of total weight,the volume of cyclohexane as water carrier is selected as 6 mL,the reaction time is 80 min and the reaction temperature is at 105 ℃.
