Gas-chromatographic studies of cadmium–olefin complexes

Abstract

CdF₂ deposited on a γ-alumina surface from aqueous HF solution has been found to interact sufficiently strongly with olefins and aromatic compounds to give very marked selective retardations of olefins and aromatic compounds when CdF₂–Al₂O₃ is used as the stationary phase in a gas–solid chromatographic column. These interactions are considerably modified by competition with water vapour, and are much weaker with other cadmium salts investigated.
