✦ Synopsis

Solid dimeric rhodium(H) acetate deposited on Corasil II gave good separation of the butenes using high-speed liquid chromatography.

Essentially, the unique order of retention times observed with gas-liquid chromatography using rhodium(H) benzoate was found, namely I-butene c tvurts-butene c isobutene c cis-butene. Similarly with silver nitrate in ethylene glycol coated on Corasil II, various olefins emerged with retention times that were in accordance with their respective silver complexation constants. This system was applied to the separation of some unsaturated natural compounds such as fatty acids, prostaglandins and pentacyclic triterpenes.
