摘要：

The prehydrolysis of beech wood in water at different temperatures and the impact of this treatment on further pulping stages were explored. Both, increased condensation degree and an increased number of free phenolic hydroxyl groups were found in the lignin isolated after prehydrolysis. An intermediate alkaline extraction (using either NaOH or MgO as base) following, the prehydrolysis was explored. Finally, acid sulfite cooks of the differently pre-treated materials were performed, and the obtained materials thoroughly analyzed.
