摘　　要：采用自制的硅胶固载硫酸镓为催化剂合成了己酸异戊酯。考察了催化剂用量、醇酸物质的量比、反应时间及催化剂重复使用次数等因素对收率的影响。结果表明,该催化剂具有催化活性高,易分离回收,重复使用性良好等优势。最佳反应条件为:己酸0.1 mol,醇酸物质的量比1.4,催化剂1.0 g,反应时间60 min,二甲苯15 mL,收率95.3%。The catalytic activity of gallium sulfate supported on silica gel in synthesizing isoamyl hexanoate was studied. The investigated effects concluded amount of the catalyst, reaction time, molar ratio of alcohol to acid, and times of catalyst reused. Experimental results showed that it was high activity and could be used repeatedly. The best conditions was as follows： hexanoic acid 0.1 mol, molar ratio of alcohol to acid 1.4 ,the catalyst 1.0 g,reaction time 60 min and xylene 15 mL,the yield could reach 95.3%.
