THE application of gasâliquid partition chromatography to organic fluorine chemistry1,2 has enabled us to extend our studies on dehydrofluorination to a nonafluorocyclohexane (I) (b.p. 92°) which has been obtained3,4 by passage of benzene vapour over cobaltic fluoride at about 150°. With concentrated aqueous potassium hydroxide, this polyfluoride (I) gave a complex mixture (b.p. 60â90°) which was shown by analytical gas-chromatography to contain nine individual components. These were separated by use of the preparative-scale gas chromatographic column, and the structures of some of them have been determined by spectroscopic examination, oxidative degradation, addition reactions, etc.
气液分配色谱法在有机氟化学中的应用1,2 使我们能够将脱氢氟化的研究扩展到无氟环己烷 (I)(b.p. 92°)。使用浓氢氧化钾水溶液时,这种多氟化物(I)会产生一种复杂的混合物(b.p. 60â90°),分析气相色谱法显示这种混合物包含九种单独的成分。使用制备级气相色谱柱分离了这些成分,并通过光谱检测、氧化降解、加成反应等方法确定了其中一些成分的结构。
