Synthesis of Isoamyl Butyrate Catalyzed by Supported Sodium Bisulfate

Supported sodium bisulfate is conveniently prepared and it has some better properties than nonsupported one in catalytic esterification reaction, such as nonhydroscopic property and being easy to conserve and use This catalyst is used to prepare isoamyl butyrate from nbutanoic acid and isoamyl alcohol The optimum conditions were as follows: basing on 02mol nbutanoic acid, molar ratio of isoamyl alcohol to nbutanoic acid was 13, amount of catalyst was 050g, reaction time was 50min On these conditions, the yield of isoamyl butyrate was 9081% The results indicated that this catalyst is one of the most efficient, economic and environmental friendly catalysts
