| Abstract: | The synthesis of cyclohexyl propanoate from propionic acid and cyclohexanol with rare earth solid superacid as catalyst was studied. The influential factors of reaction were investigated. Results show that the appropriate conditions are： molar ratio of cyclohexanol to propionic acid is 3 ： 1 ; Catalyst＇ s weight is 1.4g（ the amount of 0.1 molar propionic acid） ; Toluene is used as water - carrying reagent with 2mL; Reaction time is 3.0 h. The yield of cyclohexyl propanoate is about 90.9 % . |
