Abstract
L'invention porte sur un procédé de réduction de la teneur en produits d'extraction de pâtes à haut rendement pendant l'étape de blanchiment au peroxyde qui comprend le blanchiment au peroxyde puis l'épaississement puis le lavage, ledit procédé consistant à mettre pendant le blanchiment la pâte en contact avec un stabilisant organique et, pendant ou après, avec un tensio-actif, puis à épaissir ou laver la pâte blanchie de manière à éliminer les produits d'extraction avec la phase aqueuse. L'invention porte également sur un procédé de production de pâte à haut rendement.
