Phenolic antioxidants were identified by thin-layer chromatography in 102 samples of medical and pharmaceutical rubber articles. Acetone extracts of rubber were spotted on silica gel plates with a concentrating zone. Benzene, benzene-hexane (75:25) and benzene-ethyl acetate-acetone (100:5:1) were used as developing solvents and N-chloro-2,6-dichloro-p-benzoquinone monoimine as spray reagent. Only 8 sterically hindered phenols among the 57 previously listed were found in current use. Reasons for choosing these compounds and the experimental conditions are discussed.
通过薄层色谱法在102份医用和药用橡胶制品样品中鉴定出酚类抗氧化剂。将橡胶的丙酮提取物点样在带有浓缩区的硅胶板上。使用苯、苯 - 己烷（75:25）和苯 - 乙酸乙酯 - 丙酮（100:5:1）作为展开溶剂，N - 氯 - 2,6 - 二氯 - 对苯醌单亚胺作为喷雾试剂。在当前使用的产品中，仅发现了之前列出的57种位阻酚中的8种。讨论了选择这些化合物的原因和实验条件。
