Abstract
Procédé en plusieurs étapes pour effectuer le blanchiment de pâte cellulosique sans utiliser de chlore en milieu aqueux. Caractérisé en ce que l'on blanchit la pâte cellulosique éventuellement après un traitement préalable acide, dans une première étape avec un peroxyde ou hydroperoxyde minéral ou organique, puis dans une deuxième étape avec un peracide organique et dans une troisième étape de nouveau avec un peroxyde ou hydroperoxyde minéral ou organique.
