| 摘 要： | 在氮气保护下，研究了不同温度下维生素E的稳定性，比较了维生素E在不同溶剂（甲醇、乙醇、正已烷和油酸甲酯）中的稳定性，并研究了Fe3＋、Ca2＋、N-等金属离子对维生素E稳定性的影响。研究表明维生素E在无水甲醇溶剂中相对更稳定；金属离子Na＋严重破坏维生素E稳定性。

| Abstract: | This paper studied the stability of vitamin E at different temperatures with the protection of nitrogen gas. And the stability of vitamin E in different solvents （methanol, ethanol, n-hexane and methyl oleate） was compared. Also the effects of metal ions Fe3＋, Ca2＋, Na＋ on the stability of vitamin E were investigated. The experimental results indicated that the vitamin E was relatively more stable in anhydrous methanol solvent. And the Na＋ metal ion will lead to large damage to the stability of vitamin E. |
