| Abstract: | In this paper,by the study of the reaction of synthesis of n-butylsalicylate with the reagent phosphato tungstic acid that friendly to environment as catalyst.The optimum synthesis conditions are investigated by orthogonal experiment,too.The molar ratio of alcohol and acid is 2:1,the amount of catalyst is 7% of the mass of salicylic acid charged in the reaction,and the reaction time is 4 hours.The yield of the ester can reach to be 80.5%.This catalyst has good activity and selectivity,and friendly to environment. |
