DEF

The decomposition of wood by heating out of contact with air, producing primarily charcoal, tarry distillates and pyroligneous acid.

CONT

The destructive distillation of wood was formerly a well established industry. It was the original source of methanol ("wood alcohol") and a source of acetic acid and some other organic chemicals in addition to charcoal. ... It may be one of the least efficient methods of producing chemicals from wood.

OBS

Charcoal processes are generally called carbonization when they are mainly aimed at making charcoal, and distillation when more pyroligneous liquid is wanted.

Décomposition du bois par la chaleur en un lieu clos sans contact avec l'air, produisant du charbon de bois, des goudrons, de l'acide pyroligneux et des produits volatils non condensables.

CONT

La destilación destructiva - conocida también como pirólisis o destilación de la madera - es parecida a la carbonización, salvo que la madera se calienta en un recipiente cerrado y se recogen los gases y líquidos producidos. Algunos de esos gases pueden después condensarse para obtener una serie de productos químicos, y los que no se condensan pueden utilizarse como combustible gaseoso para el proceso mismo de destilación, o para cualquier otro fin. [...] La destilación de la madera es en realidad otro procedimiento para hacer carbón vegetal.

CONT

If the off-gases from the pyrolysis of wood are collected in some manner, then the process is termed wood distillation.

CONT

Light acetone oil is a clear transparent liquid of pale amber colour .... Heavy acetone oil is a clear liquid of deep amber colour .... Both are derived from wood distillation.

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.
