ABSTRACT OF THE DISCLOSURE This invention relates to a method for processing a tar contain- ing benzyl benzoate. According to the invention a tar containing benzyl ben- zoate is processed by subjecting it to a hydrolysis or ammonolysis reaction. Thus the benzyl benzoate with a high boiling point which is difficult to separate from some tar components by distillation is converted into the benzyl alcohol with a considerably lower boiling point in addition to the benzoic acid or a salt or amide thereof, which differs considerably in chemical pro- perties from the benzyl benzoate and the tar components. Pure benzyl alcohol can be recovered from the hydrolysed or ammonolysed mixture, e.g., by dis- tillation. Benzyl alcohol is a useful product that is used in the scents and flavours industries, Hence, it is achieved by the method according to the invention that a waste product with no applications so far is converted into a useful product.
