| Abstract: | Objcctives:To found separation method for homologous series of n-alcohols and ethyl asters of carboxylic acid.Method:Gas chromatography. Results:Cholesteric liquid crystal crown either CH-B-15-C-5 has different phase states under a range of different temperatures, and a large variety of physical properties under different operating conditions in the same temperature range. The stationary phases of CH-B-15-C-5 have three gas chromatographic fuctions; gas-solid chromatography(GSC), general gas-liquid chromatography(GLC)and crown either liquid crystal gas-liquid chromatography(CL-GLC). Conclusion:We separated n-alcohols of C 1-C 8 and ethyl asters of C 1-C 8 carboxylic acid. Good separation results were achieved using crown either liquid crysal stationary phase under a different chromatographic conditions. |
