摘要
以自制的复合硫酸铁Fe2 (SO4) 3 K2 S2 O8为催化剂 ,正丁酸与正戊醇为原料合成了丁酸正戊酯。最佳合成条件 :0 .2mol正丁酸 ,醇酸物质的量比 1.3,催化剂 1.0 g ,反应时间 30min ,酯收率达 92 .2 6 %。该催化剂具有制备简便 ,价廉易得 ,催化活性好 ,反应时间短 ,后处理工艺简单 ,无腐蚀 ,无环境污染 ,有较好的重复使用性等优点。
By using complex inorganic salt as the catalyst, n-butyric acid and n-pentanol reacted to form amyl butyrate.The optimum conditions were the followings:basing on 0.2mol n-butyric acid,molar ratio of n-pentanol to n-butyric acid was 1.3, mass of catalyst was 1.0g,reaction time was 30min.The yield reached 92.26%.Experimental results showed that the catalyst had many advantages,such as easy preparation,low cost,high activity,short reaction time, easy to use,being non-corrosive to the equipment and no pollution.
