ABSTRACT OF THE DISCLOSURE A continuous process for the production of a solvent for use in the liquefaction of coal is described. The process comprises hydrogenating a mixture of 100 parts by weight of a hydrocarbon mixture and from 0.2 to 10 parts by weight of phenol and/or alkylphenol. The hydrocarbon mixture contains at least 50% by weight of a polycyclic (from tricyclic to pentacyclic) aromatic hydrocarbon or its alkyl derivative. The hydrocarbon mixture is distilled away in a proportion of at least 80% when heated at a temperature of from 320 co 550°C. The hydrogenation of the hydrocarbon mixture and phenol and/or alkylphenol may be carried out with or without the addition of from 0.05 to 0.5% by weight (calculated as sulfur) of an easily desulfurizable sulfur compound in a high temperature and pressure hydrogen atmosphere in the presence of a catalyst containing the sulfide(s) of Group VIII metal and/or Group VI metal of the Periodic Table to prepare a partially hydrogenated product result- ing from the partial hydrogenaction of the aromatic ring of the polycyclic aromatic hydrocarbon or its alkyl derivative.
