合成了２，２，４．７－四甲基－１．２，３，４－四氢喹啉的Ｎ－羟乙基，Ｎ－氯乙基，Ｎ－乙基 衍生物。由这些衍生物出发．合成了１０个四氢喹啉甲川型分散染料。讨论了染料的 结构与吸收光谱之间的关系，发现染料的摩尔消光系数较高，但四氢喹啉的７－位上 引入甲基后，摩尔消光系数有所下降；在环己烷中染料的最高吸收波长最小，摩尔 消光系数最大；在环己烷、丙酮、氯仿、乙醇、甲苯５种溶剂中，λｍａｘ与ζｍａｘ均呈 线性关系，经 ＰＰＰ－ＭＯ计算，染料 λｍａｘ的计算值与实验值基本一致。
Synthesis of 2,2,4.7-tetramethyl-1,2, 3,4-tetrahydroquinoline N-hydroxyethyl, N-chloroethyl, N-ethyl derivatives. Starting from these derivatives. Ten tetrahydroquinoline methine disperse dyes were synthesized. The relationship between the structure and the absorption spectrum of the dye was discussed. It was found that the molar extinction coefficient of the dye was high. However, the molar extinction coefficient decreased after the methyl group was introduced to the 7-position of the tetrahydroquinoline. In the cyclohexane dye Λmax and ζmax in cyclohexane, acetone, chloroform, ethanol, and toluene were linear. The calculated value of λmax and the experimental value Basically the same.
