Abstract: A medium oil to be used for a synthesis reaction in a slurry-bed reaction procedure. The medium oil has as a main component, a branched, saturated aliphatic hydrocarbon having 16 to 50 carbon atoms, 1 to 7 tertiary carbon atoms, 0 quaternary carbon atoms, and 1 to 16 carbon atoms in the branched chains bonded to the tertiary carbon atoms; and at least one of the tertiary carbon atoms is bonded to hydrocarbon chains with a chain length having 4 or more carbon atoms in three directions, wherein the synthesis reaction in the slurry-bed reaction procedure comprises producing an oxygen-containing organic compound from a raw gas containing carbon monoxide and hydrogen.
