Programme détaillé

Lectures on acid-base catalysed degradation and oxidation reactions of
cellulose, hemicelluloses and lignin during the most relevant chemical
fractionation processes of plant biomass. Relationships between the
chemical structure and reactivity. Description of reaction rates based on the
reaction mechanisms. Laboratory works that deepen the understanding on
selected reactions and exemplify the use of analytical techniques in
monitoring the reactions.
