| Abstract: | A new catalyst named modified strong acid cation ion exchang resin by gallium sulfate was prepared.Isobutyric acid and isoamyl alcohol reacted to form isoamyl isobutyrate with it. Experimental results showed that isobutyric acid 0.2mol,molar ratio of alcohol to acid 1.5,the catalyst 1.5g,reaction time 70min and toluene 5mL,the yield is 97.0%.It also has good reusability. When its being used seven times the yield can reach 77.2%.It was the efficient,economic and environmental friendly catalyst. |
