✦ Synopsis

Oils from a lignite (Teruel, Spain) were studied. They were obtained by catalytic depolymerization, by reacting an aromatic substrate (tetralin), Lewis acid catalyst (BFJ and the lignite (oil A) or asphaltenes (oil B) at atmospheric pressure and temperatures ~220°C. The A and B oils were fractionated on an alumina-silica gel dual column into their saturated, mono-and diaromatic, polyaromatic and polar components by elution with hexane, hexane-benzene, benzene and methanolaiethyl ether-benzene respectively. The elemental analysis, average molecular weight, i.r. and 'H n.m.r. spectroscopy and aromaticity data of these subfractions were studied.
