摘要:
The present inventon relates to a sulphite fusion process for the production of celluloses using alkaline monosulphite solutions, organic solvents and quinone derivatives. The raw material to be fused is treated in a special impregnation step with either a solvent-free monosulphite solution or a solvent-water mixture.
