硝酸铁和硝酸铝在己酸异戊酯制备中催化作用探讨

Catalytic Capacity of Ferric Nitrate and Aluminum Nitrate in the Preparation of Iso-Pentyl Caproate

以己酸异戊酯的制备为例 ,探讨催化剂Fe(NO3 ) 3 ·9H2 O和Al(NO3 ) 3 ·9H2 O对酯化反应的催化活性 .较系统地研究了催化剂的用量、醇酸比、反应时间和溶剂类型对酯收率的影响 .结果表明 :Fe(NO3 ) 3 ·9H2 O具有良好的催化活性 ,反应时间短 ,并有很高的酯收率 ,而Al(NO3 ) 3 ·9H2 O对该反应的催化活性则稍低 .

The catalytic activities of Fe(NO 3) 3·9H 2O and Al(NO 3) 3·9H 2O in the preparation of iso pentyl caproate have been studied.It showed that the ester production was affected by the amount of catalyst,ration of the alcohol and the acid, the refluxing time and the types of solvents. The study also showed that Fe(NO 3) 3·9H 2O had higher catalytic activities than Al(NO 3) 3·9H 2O.
