Abstract

The invention relates to a process for the preparation of wood preservatives which have little odour and a prolonged activity and are based on aromatic, impregnating oils with a particularly low benzo[a]pyrene content, in which medium-high to high-boiling mixtures of aromatics are treated with steam in the presence of air or inert gas at 130 to 250 DEG C, with stirring and without addition of chemical auxiliaries.
