摘要
研究了克拉霉素和茜素在甲醇介质中的电荷转移反应 ,确定了最佳反应条件。研究表明 ,克拉霉素和茜素在甲醇中生成 1∶1型荷移配合物 ,该配合物的λmax=5. 34nm ,表观摩尔吸光系数ε =3 .79× 10 .3 L·mol-1·cm-1,克拉霉素浓度在12 . 8～ 180mg/L范围内符合比尔定律。
The electric charge transfer reaction of clarithromyc in and alizarin has been studied and the optimal reaction conditions have been found out.The molar ratio of the complex was 1∶1,the maximum absorption of the complex was at the wavelength of 534nm,the apparent molar absorptivity was 3.79×103L· mol -1·cm -1,clarithromycin obeyed Beer′s law in the concentration range of 12.8～180mg/L.
