| The Retention of Six-, Seven-, Eight-, and Twelve-Membered Ring Molecules of Type SexS v in Reversed-Phase HPLC. Prediction of Retention for Unknown Se^S^. Heterocycles and Analysis of Sulfur-Selenium Melts [1]  | | | | Abstract
| The HPLC retention times o f 25 cyclic com pounds o f type SevSv (x = 0 8; y = 0 12) have been measured under identical conditions and are used to evaluate the factors which determine the retention. Linear relationships are derived for the dependence o f retention (Ink'-, k' = capacity factor) on ring size, number o f Se atoms, and number o f SeS bonds per molecule for six-, seven-, eight-, and twelve-membered SevSv rings. These relationships allow the prediction o f retention times for all SeY S t. heterocycles o f these ring sizes (ca. 100 com pounds). The results are applied to the qualitative analysis o f mixed sulfur-selenium melts o f two com positions: at a molar ratio o f S : Se = 8.7 twenty-one HPLC signals have been observed for the CS2 extract o f the quenched melt and assigned to SevSv rings o f sizes 6 • • • 12. At S :S e = 0.33 mainly six-, seven-, and eight-membered species with cumulated Se atom s have been found. | | | |
