An Application of Aryl Stationary Phases for Separation of Select Organogermanium Compounds

摘要: Abstract In this paper are reported the results of continuation investigations concerning optimization chromatographic process benzylgermanium derivatives. Optimal conditions separation and determination have been elaborated for di‐, tri‐, tetra‐benzylhalogeno germanium derivatives using aryl stationary phases. Interaction a π-π type between phase chromatographed compound exhibited predominance in process. During numerous difficulties were observed. These caused, as had shown earlier experiments, by column surface modification. Three phases two mobile taken under consideration. The best selectivity factors α1=3.50 α2=1.46 obtained RP Si‐PGC pure dichloromethane. Slightly worse yielded with naphthyl phase.
