| Abstract: | It has studied the catalytic activity of silicotungstic acid as catalyst in synthesis ethyl acetate. Discussed the quantity of catalyst, the time of reaction and effect of the alcohol and ratio of acid on rate of the reaction. Under the optimum conditions, rate of production was 92.21%, which is better than using the sulphurie acid. And it was studied the reusing of catalyst. |
