Abstract

1. Process for the production of pulp from lignocellulose materials in the presence of organic, cyclic compounds containing keto and/or hydroxyl groups, characterized in that the organic, cyclic compounds containing keto and/or hydroxyl groups are employed in the form of granules, which are obtained by granulating the organic, cyclic compounds containing keto and/or hydroxyl groups and optionally other constituents of the granules in finely divided form by spraying with water or an aqueous liquid in an amount of 5 to 30 % by weight (relative to the finely divided constituents of the agent), and the granules thus obtained are dried.
