Abstract
This paper presents the results obtained using the prehydrolysis treatments of rapeseed stalks depending on regime and the
catalyst. The vegetal materials were subjected under different temperature conditions and then characterized for the yield
reducing substances. The differences between samples have been established by using FTIR and depend on the successive
hydrolytic treatments of dynamic and static regime in the presence of various catalysts. The experimental data show that the
hydrolysis reaction induces the modification of cellolignin functionality.
