✦ Synopsis

The etllciency of polymeric Schiff base complexes as solid phases for the chromatographic separation of low-molecular-weight gases was tested with respect to three variations of the complexes: the central metal ion, the amine bridge and substitution of the methylene group between the two aromatic rings. An optimum effect was achieved with V*+ and Cr*+ as central ions, a C&Z, chain between the two nitrogen atoms and either one toluene or cumene group on the methylene bridge. Some special effects concerning the separation of O2 are mentioned.

However, as a solid phase for GC separations, only one complex (M = Cr*+, R = CaH10-CH2-C6H10, R = I-I) has been tested so far3s6.
