| Abstract: | The reaction conditions for synthesis of iso-amyl acetate are studied from acetic acid and iso-amyl alcohol upon strong acid cation exchange resin as a catalyst and cyclohexane as water-carrying agent.Factors on esterification yield such as raw material ratio,catalyst consumption,reaction time are discussed.The best conditions are found as follow: acetic acid / iso-amyl alcohol = 1/1.5(mol ratio),the quality of catalyst is equal to 2.7% feed stock,refluxing reaction time is 1.2 h and the yield of iso-amyl acetate is 79.0%.While the catalyst is reused for 6 times,the yield is down to 64.6%.The catalyst has many advantages,such as high activity,good stability,easy preparation,low cost,easy post treatment process.It is also non-corrosion and non-pollution to the environment and can be used repeatedly. |
