Abstract
1,4,7,10,13,16-Hexathiacyclooctadecane was used as gas chromatographic(GC) stationary phase.Its proper concentrations,polarities,heat-durabilities and chromatographic properties were studied.The samples including halogenated hydrocarbons,aromatics,ketones,phenols,alcohols,and aniline derivatives were separated.The results are as follows: 1) The polarities of stationary phase with the mass ratio of 15% are middle,and the average is 815 at 120 ℃;2) The temperature in using 1,4,7,10,13,16-hexathiacyclooctadecane is limited under 185 ℃;3) It has fine chromatographic separation faction(α) to some compounds.Above data indicate that the stationary phase has fine chromatographic properties and it is promising GC stationary phase.
