Golovnya, R. V. published the artcileRetentions of alkyloxazoles and alkylthiazoles and their prediction based on non-linear additivity concepts in gas chromatography, Name: 4,5-Dimethyloxazole, the publication is Journal of Chromatography (1991), 552(1-2), 1-12, database is CAplus.
The gas chromatog. (GC) behavior of 39 alkyloxazoles and alkylthiazoles was studied on three capillary columns with OV-101-KF, Triton X-305-KF and PEG-40M-KF. The regularities in the thermodn. characteristics of sorption of azoles having O or S atoms were established. Energy contributions of Me, Et and Pr groups to the partial molar free energy of sorption of alkyloxazoles and alkylthiazoles were determined It was found that the contributions of the same alkyl group are different and dependent on the nature of the heterocycle and the position of the alkyl group with respect to the heteroatoms in the azole ring. Two methods for the prediction of retention indexes on the basis of the analogy of the GC behavior of azoles and inconstancy of the contributions of the same alkyl groups are given. The predicted retention indexes are in good agreement with the exptl. values.
