Fifty-four amines used as antioxidants and/or antiozonants for elastomers were separated on silica gel thin-layer plates with benzene and benzene-ethyl acetate-acetone (100:5:1) as developing solvents and N-chloro-2,6-dichloro-p-benzoquinone monoimine in buffered alkaline medium as spray reagent. Benzene-n-hexane (50:50) was used to separate diheptyl- and dioctyldiphenylamines. The active agents of several imprecisely defined products were identified and the relationships between some mixtures were elucidated. The method highlights the numerous minor components of these very impure industrial compounds. Some theoretical correlations between the chemical structures, the RF values and the colours of the spots were also established.
以硅胶薄层板为载体，用苯和苯 - 乙酸乙酯 - 丙酮（100:5:1）作为展开剂，在缓冲碱性介质中用N - 氯 - 2,6 - 二氯对苯醌单亚胺作为喷雾试剂，分离了用作弹性体抗氧化剂和/或抗臭氧剂的54种胺类物质。用苯 - 正己烷（50:50）分离二庚基二苯胺和二辛基二苯胺。鉴定了几种成分不明确产品的活性剂，并阐明了一些混合物之间的关系。该方法突出了这些非常不纯的工业化合物中的许多次要成分。还建立了化学结构、比移值（RF值）和斑点颜色之间的一些理论相关性。
