Chromatographic properties of type X zeolites containing cations of sodium, magnesium, calcium, strontium and barium were investigated using a model mixture of C1−C4 hydrocarbons, carbon monoxide and hydrogen. It is shown that the cation nature at

The separation of diastereomeric C 8 C 20 alkanes using mesogenic stationary phases has been studied. A comparison of the retentions of the diastereomers on mesogenic and non-mesogenic phases showed the effect of the mesophase diastereoselectivity

In gas chromatography on zeolites “active” carrier gases such as water vapour and carbon dioxide are rarely used because they are adsorbed on zeolites selectively and strongly. It is shown here that the use of carbon dioxide as the carrier gas al

The separatiing properties of tuffs containing clinoptilolite adn mordenite as adsorbents in gas chromatography were studied, using argon—oxygen—nitrogen—methane—carbon monoxide as a model mixture. It was shown that the treatment of tuffs con

The possibility of using different types of zeolites of both synthetic and natural origin for the chromatographic separation of low-boiling inorganic and C1-C4 hydrocarbon gas mixtures is shown. A large effect of the zeolite structure and its cation

New solid supports have been prepared from rocks such as perlite and volcanic slags by alkali—acid treatment. Their physico-chemical characteristics (bulk density, specific surface area, pH, mechanical strength) are similar to those of solid suppor
