摘要/Abstract

摘要： 本文利用高效液相色谱法测定了色满类,双螺色满类,对一甲氧基苯酚类和双螺茚类抗氧化剂与单重态氧反应的物理猝灭速率常数和化学猝灭速率常数。实验结果表明,抗氧化剂猝灭单重态氧的过程以物理猝灭为主,物理猝灭速率常数和总猝灭速率常数愈大,品红甲亚胺染料的防褪色效果愈好,但存在一极限褪色率。

关键词: 甲亚胺染料, 彩色影像稳定性, 抗氧化剂, 高效液相色谱

Abstract: In this paper the physical and chemical quenching rate constants of antioxidants such as chroman,spirochroman,p-methoxyphenol and spirobiindene quenching singlet oxygen have been measured by high performance liquid chromatography.It was found that the physical quenching was the chief way in the quenching processes.The larger the physical quenching rate constant and total quenching rate constant are,the better the effect of antifading is.But there is a limit to the antifading ability of magenta azomethine dye.

Key words: azomethine dye, antioxidant, stability of color image, high performance liquid chromatography
