Abstract
In the presence of Sncl4.5H2O catalyst,propionice acid and isopentanol reacted to form Isoamyl propionate. The optimum conditions were as follows: 0.2mol n-propionic acid; molar ratio of isopentanol to n-propionice acid:1:3:1; mass of catalyst:2.0g; reaction time:60min. Under these conditions the yield of isoamyl propionate was 92.3%. Experimental results showed that the catalyst had many advantages, such as high activity, good stability, easy preparation, low cost, easy post-treatment process and no need of using taking-water agent. It was also non-corrosive and non-pollutant to the environment, and it could be used repeatedly.
