| titleOfInvention | A process in a (d) stage bleaching of hardwood pulps in a presence of mg(oh)2 |
| 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 CIO2 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 pulp with a bleaching agent comprising ClO2 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. |
