| Abstract: | Iso-Amyl acetate was composed with Acetic acid and iso-Amyl alcohol used as starting materials, choosing sodium hydrogen sulfate as catalyst. We first studied different conditions which affect the composition of ester, such as, different reaction time, different quantity of catalyst and different rate of acid and alcohol. We found an optimum reaction condition. Results from experiments indicate, compared with the traditional method of dense sulfuric acid catalysis, sodium hydrogen sulfate is used as catalyst which has more advantages, such as, it had shorter reaction time, higher catalytic efficiency and higher product yield,and it had less pollution to our environment and so on. |
