SUSTAINABLE CHEMICAL TECHNOLOGIES LABORATORY
Learning outcomes of the course unit
The course proposes specific experiments regarding topics of catalysis applied to various industrial processes. Examples of homogenous, heterogenous, enzymatic catalysis, leading to the formation of C-C, C-N, C-O, C-H bonds, will be experimentally examined.
Course contents summary
The course includes frontal lessons concerning the theoretical grounds of the laboratory experiments.
The following experiments will be carried out:
1) Methasis (ROMP): synthesis and characterization of monomer; polymerization in homogeneous phase with Ruthenium-based catalyst; separation and characterization by NMR of the polymer obtained;
2) Catalytic alkylation p-xylene
3) Chemical reduction and enzimatic resolution: chemical reduction of a ketone and resolution of the racemic mixture via enzyme (lypase); recovery of the products via chromatography and polarimetric measures of alpha;
4) Catalytic synthesis of an urea: carbonylation reaction of an amine under pressure, in supercritical carbon dioxide as a solvent; recovery and characterization of the product;
5) Heck reaction: synthesis of stylbene from Iiodobenzene and styrene, with palladium-based catalyst, under homogeneous conditions.
