摘要

描述了 Tokem-308 阳离子岩（KU-2x8 的类似物）在 12 M HNO3 汽化后得到的 HNO3（蒸汽）-空气气氛中的化学变化。Tokem-308 样品在这种气氛中于 403-443 K 下经过 4-24 小时的气相处理后，其某些物理（质量、颜色等）和化学（在 H2O、NaOH、C2H5OH 和丙酮中的溶解度）特性发生了变化。在 Tokem-308 树脂在 HNO3（蒸气）-空气气氛中的转化产物中发现了 2,4-二硝基苯乙酸和对硝基苯甲酸。

Chemical Destruction of Tokem-308 Cationite (Analog of KU-2x8) in the HNO3(vapor)–Air Atmosphere

The chemical transformation of the Tokem-308 cationite (analog of KU-2x8) in an HNO₃(vapor)–air atmosphere obtained as a result of vaporization of 12 M HNO₃ is described. The gas-phase treatment of Tokem-308 samples in this atmosphere at 403–443 K for 4–24 h changes some of their physical (mass, color, etc.) and chemical (solubility in H₂O, NaOH, C₂H₅OH, acetone) properties. 2,4-Dinitrophenylacetic acid and para-nitrobenzoic acid were found among the products of the transformation of the Tokem-308 resin in the HNO₃(vapor)–air atmosphere.
