| Popis: | 21 C 10 -C 16 hydrocarbons, 7 each of n -paraffins, 2-methyl alkanes and α-olefins, were identified in a low-temparature bituminous coal tar by means of gas-liquid chromatography. Quantitative determinations were made on all of these constituents. It was found that the curves for the plots of logarithms of relative retention against normal boiling points for C 10 -C 16 n -paraffins and α-ole fins are parallel. A similar parallel curve for the 2-mathyl alkane series was derivred, using the Known point for 2-methyl decane. This correlation curve was used for the identification of several 2-methyl alkalnes. Naphthenes and trans -olefins were found in small amounts. |
