Sinteza tipa B beta -O-4 ligninskega modela

diplomsko delo

Jure Valenčič (Author), Jernej Iskra (Mentor)

Abstract

Liginin je makromolekula sestavljena iz fenilpropanskih enot zamreženih preko etrskih vezi, med katerimi prevladujejo beta-O-4 vezi. Molekula lignina je zelo kompleksna, zato se za študij njegove reaktivnosti in tudi strukture pogosto uporabljajo modelne molekule. V diplomskem delu se bom tako posvetil sintezi modela, ki vsebuje beta-O-4 vez, kar lahko na primer poenostavi študij depolimerizacije lignina, analizo produktov, ki nastanejo pri depolimerizaciji lignina in razumevanje njenega mehanizma. V sedanjem času je depolimerizacija lignina eden izmed bolj perspektivnih postopkov pridobivanja aromatskih molekul iz trajnostnih virov, zato je zanimanje za raziskave veliko. S samo sintezo modelne molekule želim tudi prispevati k boljšemu razumevanju kompleksnosti lignina.

Secondary title:	Synthesis of selected beta-O-4 ligning model compound
Secondary abstract:	Lignin is a macromolecule composed of phenylpropyl units cross-linked by ether bonds, with beta-O-4 bonds predominating. Lignin molecule is very complex, so model compounds are usually used to study its reactivity and structure. In my diploma thesis I will focus on the synthesis of a model containing a beta-O-4 bond – this model can simplify the study of depolymerization, the analysis of products of depolymerization and the mechanism itself. Currently, the depolymerization of lignin is one of the most promising processes for the production of aromatic molecules from sustainable sources – thus, the interest in lignin model compounds is high. With the synthesis of lignin model compound, I would also like to contribute to a better understanding of the complexity of lignin itself.
