dagmar goeke Biodegradable plastics and biocompatible composites, generated from renewable dagmar goeke dissertation example feedstock, are regarded as promising dagmar goeke dissertation example that could replace synthetic polymers and reduce global dependence on fossil fuel sources. Wood cellulose, the most abundant biopolymer on earth, holds great potential as a renewable biomass feedstock for the future.
To unlock the entire scope of potential benefits of this feedstock, the wood components—namely cellulose, hemicellulose and lignin —need to be separated and processed individually.
Current methods to separate wood components, such as Kraft pulping for example, suffer considerable drawbacks and cannot be considered environmentally benign. This work investigates the use of food -additive derived ionic liquids ILs for separating wood ligninstudying the influence of selected dissertation example parameters, such as extraction time, extraction temperature, IL moisture content, wood particle size, wood species, IL cation species, solvent composition, and IL recyclability on the lignin extraction dissertation example.
The lignin extract and the wood residues were characterised via infrared spectroscopyelemental dagmar goeke dissertation example analysisdifferential scanning calorimetryDagmar goeke dissertation example diffractionand gel permeation chromatography. Dagmar goeke dissertation example conditions during IL treatment did not decrease the crystallinity of the wood sample, and the extracted lignin homework excuses quotes dagmar dagmar goeke dissertation example dissertation example a larger molar mass and dagmar goeke dissertation example more uniform link mass distribution, compared to commercially available Kraft lignin.
