Abstract

A successive extraction of bitumes from black coal was carried out using the following solvents: petroleum ether, petroleumether-benzene (1∶1), benzene, benzene-ethyl ether (1∶1), ethyl ether, ethyl ether ethanole (1∶1), ethanol. These extract organic products as follows: 0.06, 0.16, 0.11, 0.21, 0.07, 0.29 and 0.70% respectively. The obtained by the above mentioned solvents chujniuds were compounds to the thermal and IR-spectral analysis.

Zusammenfassung

Mittels folgender Lösungsmittel wurde eine sukzessive Extraktion von Bitumen aus Steinkohle durchgeführt: Petrolether, Petrolether-Benzol (1∶1), Benzol, Benzol-Ethylether (1∶1), Ethylether, Ethylether-Ethanol (1∶1), Ethanol. In dieser Reihenfolge konnten organische Produkte zu 0.06, 0.16, 0.11, 0.21, 0.07, 0.29 bzw. 0.70 % extrahiert werden. Die durch aufgeführte Lösungsmittel erhaltenen Verbindungen wurden einer Thermound einer IR-Analyse unterzogen.
