A process for the production of chemical pulp, in which wood is treated with a cooking liquor essentially not containing any polysulphide, and in which, prior to the treatment, the cooking liquor does essentially not contain any carbonate, and the concentration of added hydroxide ions in the cooking liquor is < 0.2 M, and that the cooking liquor also contains anthraquinone and/or derivatives thereof.
