Abstract

Thin layer chromatography and chemical detection procedures for barbiturates are described and the reaction mechanism introduced. We show that by this technique barbiturates can be characterized as long, intermediate, short, and very short acting, with a few exceptions, by Rf value and by the typical spot color hue. The factors involved and chemical requirements for color are mentioned, e.g. 1. Behavior in organic solvents 2. Silica Gel polarity and pH 3. Functional groups responsible for interaction with the reagent 4. pH and chemicals of the color developer 5. Mechanism of reaction.

巴比妥酸盐化学:分离、薄层色谱鉴别及反应机理。
介绍了巴比妥酸盐的薄层色谱法和化学检测方法,并介绍了反应机理。我们表明,通过这种技术巴比妥酸盐可以表征为长,中间,短,和非常短的作用,除了少数例外,通过Rf值和典型的专色色调。提到了所涉及的因素和颜色的化学要求,例如:1。在有机溶剂中的行为硅胶极性和pH值3。负责与试剂相互作用的官能团。显色剂的pH值和化学成分反应机理。
