| Abstract: | N-butyl acetate is synthesized from acetic acid and n-butanol,using KAl(SO4)2 as the catalyst.The influences of reaction conditions on the esterification rate are investigated by means of the orthogonal experiment designing.The optimum reaction condition is obtained as follows: 0.1mol acetic acid,molar ratio of acetic acid to n-butanol,1:1;and KAl(SO4)2 is 8.33% of the weight of acetic acid;the reaction time,1h.The esterification rate of over 97.7% is obtained. |
