Summary
The separation of C1–C4 nitroparaffins on SE-30, PEGA and Porapak R stationary phases was investigated. The nitroparaffin mixture was obtained from a real technological process. The best separation was achieved on Porapak R at 190°C. The fact that each peak obtained from this column corresponded to a single compound was checked by utilizing the linear relationship between the peak widths and the adjusted retention times (t′ R ). Peak identification was carried out using the chromatographic data only, with help of plots of log t′ R vs. carbon number and log t′ R vs. boiling point; some of the results were also confirmed with comparing the retention times with those of pure substances and IR investigation of the collected chromatographic fraction.
