Patent Abstract

Method for extraction of soluble organic material from rock pores of a rock with micropores, macropores and dead pores, characterized in that the rock is comminuted and sieved to a grain fraction of 0.63 mm - 2.0 mm in a first process step and subsequently extracted with an organic solvent, the extracted grain fraction is extracted in a second process step with a mixture of 30 mass percent methanol, 38 mass percent acetone and 32 mass percent chloroform, and that the rock of this fraction is reduced to a grain size of
