Description of the Division of Chemistry of Renewables

The Division of Chemistry of Renewable Resources (Chair of Wood, Pulp and Fiber Chemistry) at the Department of Chemistry is concerned with fundamental and applied research in the field of wood and plant constituents, such as polysaccharides, lignin, and extractives, biorefineries, paper, biomaterials and green chemistry aproaches. The research focuses on the following topics:

  • Cellulose chemistry and analysis (structural chemistry, dissolution of cellulose and cellulose solvents, cellulosic fibers, aging chemistry and conservation chemistry, bleaching chemistry, nano-structured cellulosic materials) and polysaccharide chemistry in general
  • Lignin chemistry and analysis (structural analysis of native and technical lignins, lignin separation and fractionation, utilization approaches for lignins and technical lignins, such as Kraft lignins and lignosulfonates)
  • Biopolymer analysis with an emphasis on cellulose and polysaccharide analytics (molecular weight distributions, profiles of functional groups, substituent distributions, oxidative modifications, chromophore analysis, structural analysis)
  • Conservation science of cellulosic objects (damage assessment, development and application of conservational measures, non-destructive analytical techniques) 
  • Chemistry and development of phenolic antioxidants (structure-property relationships, novel tocopherol derivatives, multifunctional stabilizers, phenolic extractives)
  • Biomaterial chemistry (hydrogels, aerogels, carbogels, mikro- and nanostructured materials, nanocomposites)
  • "Green Chemistry" (sustainable and environmentally compatible chemical reactions, solventless, energy-saving and atom-economical reactions, microwave-supported syntheses, new reaction media)

The methods employed encompass the entire spectrum of organic synthesis with accompanying analyses (cellulosic and phenolic model compounds, cellulose derivatives, isotopic labeling, heterocyclic chemistry), structural aspects (solid-state, gel and solution NMR, EPR, crystal structure analysis) as well as specialized analytical techniques (gel permeation chromatography with multiple detection and other hyphenated chromatographic techniques).

State-of-the-art laboratories and equipment are placed at the disposal of a very active work group with about 40 members from all over the world, engaged in many national and international collaborations.

As services, several aspects of advanced cellulose analytics, lignin analysis, and antioxidant chemistry are offered
