Abstract：The catalytic activity of some inorganic salts in esterification of propanoic acid with butanol was compared. The results showed that the catalytic activity of titanium sulphate was very good. The optimun condition was as follows: molar ratio of propanoic acid to butanol 1.1∶1,reaction temperature 145℃,reaction time 1h, the amount of titanium sulphate 2.0%. In the condition, the yield was 97%.

Key words：inorganic salt; titanium sulphate; butyl propanoate; catalytic esterification
