摘要
进一步研究了高纯氧化钕(99．5 %)催化合成乙酸异丁酯的性能。采用文献[1]的反应条件,经多次实验证明:实际酯收率只有58％,远达不到文献[1]中数据(酯收率80％)。此外又进一步采用了纳米级氧化钕催化合成酯,酯收率也只有66％左右。因此文献[1]中80％的酯收率有待于进一步商榷和考证。
Synthesis of isobutyl acetate catalyzed by Nd2O3 （purity is 99.5%） from acetic acid with iso-- Butyl alcohol was studied further. The ester yield in our experiments is about 58%, which is different from the result in the previous literature （yield 80%）. And the ester yield using Nd203 nanopowder is about 66%, which is not reached 80%. The reason in detail need to be investigated furthermore.
