| Abstract: | Summary Group separation of malthene fractions of tar samples obtained from brown coals of different ranks at two different temperatures (500 and 800°C) was performed by HPLC using amino-cyano bonded phase packing with two eluent systems of different polarities and backflushing technique. Group composition of different tar samples was compared and evaluated. Amount and distribution of volatile compounds in the malthene fractions were determined by capillary gas chromatography on a CP-Sil 5 WCOT column. Presented at the 15th International Symposium on Chromatography, Nürnberg, October 1984 |
