Abstract
The retardation factors and specific retention volumes of pyridine and its derivatives are determined via inverse gas chromatography in the 130–170°C range of temperatures on packed columns with silicone-based XE-60 stationary phases and additives of camphor-substituted tetrapyrazinoporphyrazine or its copper complex. The separation factors of sorbates with close boiling temperatures are calculated, and the high separation ability of the binary XE-60 silicone–pyrazinoporphyrazine Cu(II) complex phase is established. The thermodynamic characteristics of the sorption of pyridine and methyl- and dimethylpyridine isomers from the gas phase are determined along with the macroheterocyclic compound–sorbate complexation constants and thermodynamic parameters. The high selectivity of a sorbent based on XE-60 silicone and the copper complex of camphor-substituted tetrapyrazinoporphyrazine is substantiated thermodynamically.
