Abstract

New geometric isomers, methyl (9Z,11Z)-13-hydroperoxy-9,11-octadecadienoate and methyl (10Z,12Z)-9-hydroperoxy-10,12-octadecadienoate, were proved to be present in methyl linoleate hydroperoxide produced by autoxidation. They were identified from their UV, MS, and 1H-NMR spectra after conversion to the corresponding oxo derivatives: methyl (9Z,11Z)-13-oxo-9,11-octadecadienoate and methyl (10Z,12Z)-9-oxo-10,12-octadecadienoate. Their chromatographic behavior is described.

摘要

新的几何异构体，即甲基(9Z,11Z)-13-氢过氧-9,11-十八碳二烯酸酯和甲基(10Z,12Z)-9-氢过氧-10,12-十八碳二烯酸酯，被证实在自动氧化产生的亚油酸甲酯氢过氧化物中存在。在转化为相应的氧代衍生物，即甲基(9Z,11Z)-13-氧代-9,11-十八碳二烯酸酯和甲基(10Z,12Z)-9-氧代-10,12-十八碳二烯酸酯后，通过它们的紫外光谱、质谱和1H-核磁共振光谱对其进行了鉴定。描述了它们的色谱行为。
