Ozone organosolv bleaching of radiata pine kraft pulp

The effect of organic solvents on the selectivity and brightness of high consistency ozone bleaching of radiata pine I(raft-oxygen pulp was investigated. Among several organic compounds, formic acid is the most attractive one, as this solvent improves ozone delignification and, efficiency and also p...
