CONT

La distillation du bois permet d'obtenir principalement du charbon de bois, des goudrons et de l'acide pyroligneux. Les bois résineux donnent une essence dite "essence de pin", succédané de l'essence de térébenthine. L'opération dure 15 heures, à des températures montant de 350° C à 430° C dans des gigantesques cornues pouvant contenir jusqu'à 2 tonnes de bois. Jadis, l'acide pyroligneux était à la base des fabrications d'acétone et d'acide acétique, que l'on obtient maintenant par synthèse.
