Biosourced chemistry

The following topics will be covered:

- Biobased solvents

- Biomass fuels

- Antioxidants derived from lignin

- Metal catalysts from plants

- Surfactants obtained from renewable resources

- Examples of industrial applications of enzymatic synthesis

Hourly volumes* :

CM: 15

TD : 5

The aim of this course is to study the substitution of molecules of petrochemical origin (e.g. fuels, solvents) by biobased molecules with similar functionalities, as well as the creation of new molecules with innovative functionalities (e.g. detergents).
