Abstract When optimizing the process parameters of the acidic ethanolic organosolv process, the aim is usually to maximize the delignification and/or lignin purity. However, process parameters such as temperature, time, ethanol and catalyst concentra

Although several successful applications of benchtop nuclear magnetic resonance (NMR) spectroscopy in quantitative mixture analysis exist, the possibility of calibration transfer remains mostly unexplored, especially between high- and low-field NMR.

Types of lignin, properties, and structural characterization techniques

Autor: Xuan Tung Do, Margit Schulze, Yulia B. Monakhova, René Burger, Jessica Rumpf

The chemical structure of lignin, that is, the monolignols and their linkages, is dependent on the biomass type and the procedure used for lignin isolation. The resulting structural differences also influence the lignin’s properties such as antioxi
