| titleOfInvention | Process of bleaching hardwood pulps in a D1 or D2 stage in a presence of a weak base |
| abstract | This invention relates to an improved bleaching process for bleaching pulp comprising at least one bleaching stage which comprises treating a hardwood pulp with a bleaching agent comprising ClO 2 in the presence of a weak base such as, for example, Mg(OH) 2 preferably at pH from about 3.5 to about 6.5. The invention is also relates a bleaching process for bleaching pulp having two or more bleaching stages, at least one of which and preferably two of which comprises treating a hardwood pulp with a bleaching agent comprising ClO 2 in the presence of a weak base such as, for example, Mg(OH) 2 preferably at pH from about 3.5 to about 6.5. |
