    摘要: Oil shale or tar sands is extracted under non-thermally destructive conditions with a solvent liquid containing a compound having the general formula: ##STR1## where M is a carbon, sulfur, or phosphorus atom,R.sup.2 and R.sup.3 are each a hydrogen atom or a lower alkyl group,R and R.sup.1 are each a lower alkyl group, another ##STR2## a monocyclic aromatic group, or R.sup.1 can be another ##STR3## or R.sup.1 and R.sup.2 together can represent the atoms necessary to close a heterocyclic ring, andn=1 where M=phosphorus and is otherwise 0,to substantially remove the non-fixed carbon content of the oil shale or tar sands, leaving a solid residue of fixed carbon, ash minerals, and non-extractable matter.
