维生素E又名生育酚,有α、β、γ及δ四种。本文所指的维生素E是α-生育酚即为2,5,7,8-tetramethyl-2-(4’,8’,12’-trimethyl-tridecyl)-δ-chromanol。其结构式为(图A)及其对映体。它对人体有抗不育症的重要的生物活性,对维生素E的电化氧化机理进行探讨,将有助于揭示它在人体内的氧化化学特性。Kolthoff等人曾研究了维生素E在滴汞电极上的电化学行为。Parker报导了维生素E模型化合物(图B)的阳极氧化,并提出其反应机理。但关于维生素E的阳极氧化机理至今未见报导。本文对维生素E在乙腈、乙醇等不同溶剂中的阳极氧化进行了研究,探讨其氧化
Vitamin E, also known as tocopherol, α, β, γ and δ four. As used herein, vitamin E is α-tocopherol which is 2,5,7,8-tetramethyl-2- (4 ’, 8’, 12’-trimethyl-tridecyl) -δ-chromanol. Its structure is (Figure A) and its enantiomers. It has an important biological activity against human infertility, and discusses the electrochemical oxidation mechanism of vitamin E. It will help to reveal its oxidative chemical properties in the human body. Kolthoff et al. Studied the electrochemical behavior of vitamin E at the droplet mercury electrode. Parker reported anodic oxidation of vitamin E model compounds (Panel B) and proposed their reaction mechanism. However, the mechanism of anodizing vitamin E has not been reported yet. In this paper, vitamin E in acetonitrile, ethanol and other solvents in anodic oxidation was studied to explore its oxidation
