| 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。

| Abstract: | 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 Nd2O3 nanopowder is a-bout 66%, which is not reached 80%. The reason in detail need to be investigated furthermore. |
