摘要

A cation-substituted clay mineral obtained by substantially substituting a low-valency metal-ammine complex and/or a low-valency metal-amine complex for the interlayer cations of a water-swellable clay mineral. A chromatographic packing comprising the above mineral permit a sharp peak to be obtained for a highly unsaturated compound and is resistant to a change caused by solvents, thus being usable stably for long.
