幾種無(wú)機鹽催化合成丙酸丁酯
毛立新(岳陽(yáng)師范學(xué)院化工系; 湖南岳陽(yáng))
摘 要:比較了幾種無(wú)機鹽在合成丙酸丁酯中的催化活性 ,結果表明 ,硫酸鈦的催化酯化活性最好 ,優(yōu)化條件如 :酸∶醇 =1.1∶1(mol/mol) ,反應溫度 145℃ ,反應時(shí)間 1h ,催化劑用量(以丁醇為基數 )為 2 .0 %。優(yōu)化條件下 ,轉化率可達 97%
關(guān)鍵詞:無(wú)機鹽; 硫酸鈦; 丙酸丁酯; 催化酯化

Comparison of Catalytic Activity of Some Inorganic Salts in Esterification of Propanoic Acid with Butanol
MAO Li xin (Department of Chemical Engineering; Yueyang Norrnal College; Yueyang 414000; China)
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
