Prediction of the retention of beta-diketonato complexes in TLC systems on silica gel by quantitative structure-retention relationships
Predviđanje retencije β-diketonato kompleksa u TLC sistemima na silika-gelu primenom kvantitativnog odnosa strukture i retencije
Apstrakt
Quantitative structure retention relationships for a series of 30 mixed beta-diketonato complexes of cobalt(III), chromium(III) and ruthenium(III) were derived by multiple linear regression analyses using molecular descriptors obtained by quantum chemical calculations. The retention parameters were obtained by thin layer chromatography on silica gel using mono and two-component solvent systems. The molecular descriptors included in the multiple linear regression analysis were molecular weight, molecular volume, surface area, hydrophilic lipophilic balance, percent hydrophilic surface area, dipole moment, polarizability, refractivity, energy of the highest occupied molecular orbital and energy of the lowest unoccupied molecular orbital. High agreement between the experimental and predicted retention parameters was obtained when polarizability and the hydrophilic lipophilic balance were used as the molecular descriptors. Comparison of the models with those established on polyacrylonitril...e showed that the structure of the sorbent is responsible for the chromatographic behaviour of the same compounds. The presented models can be used for the prediction of the retention of new solutes in screening chromatographic systems.

Retencioni parametri su dobijeni tankoslojnom hromatografijom na silika-gelu primenom mono-i dvokomponetnih rastvarača. Molekulski deskriptori koji su uključeni u multilinearnu regresionu analizu su molekulska težina, molekulska zapremina, površina, hidrofilni-lipofilni balans, procenat hidrofilne površine, dipolni momenat, polarizabilnost, refraktivnost, energija najviše zauzete molekulske orbitale i energija najniže prazne molekulske orbitale. Dobijena je zadovoljavajuća korelacija između eksperimentalnih retencionih parametara i retencionih parametara predviđenih postavljenim modelima, koji sadrže polarizabilnost i hidrofilni-lipofilni balans kao deskriptore.
