Tuning Lignin Characteristics by Fractionation: A Versatile Approach Based on Solvent Extraction and Membrane-Assisted Ultrafiltration [PDF]

open access: yesMolecules, 2020
Technical lignins, typically obtained from the biorefining of lignocellulosic raw materials, represent a highly abundant natural aromatic feedstock with high potential in a sustainable economy scenario, especially considering the huge primary production ...

Kumagawa and Soxhlet Solvent Fractionation of Lignin: The Impact on the Chemical Structure. [PDF]

open access: yesACS Omega, 2022
We investigated the effects of solvent fractionation on the chemical structures of two commercial technical lignins. We compared the effect of Soxhlet and Kumagawa extraction. The aim of this work was to compare the impact of the methods and of the solvents on lignin characteristics.

Solvent Fractionation Improves the Functional Properties of Sheep Rump Fat: Effects of Different Lipid Fractions on Lipid Metabolism and Gut Health in Mice [PDF]

open access: yesFoods
To enhance the nutritional value of sheep fat, high-melting-point solid fat (HSO) and low-melting-point liquid oil (LSO) were prepared from Altay sheep rump fat via solvent fractionation.

Solvent screening for the fractionation of industrial kraft lignin [PDF]

open access: yesHolzforschung, 2015
AbstractThe polydispersity of commercially available kraft lignins (KLs) is one of the factors limiting their applications in polymer-based materials. A prerequisite is thus to develop lignin fractionation strategies compatible with industrial requirements and restrictions.

Quantitative prediction of the solvent fractionation of lignin [PDF]

open access: yesGreen Chemistry, 2023
A combined experimental and theoretical framework was developed that predicts the solvent fractionation of lignin, taking chemical and physical dispersity into account. This paves the way for a broader applicability of lignin in bio-based materials.

Solvent Fractionation of Technical Lignin Materials with Industrially Relevant Solvents [PDF]

open access: yesPeriodica Polytechnica Chemical Engineering
Lignin fractionation aims at dividing the original lignin material into more uniform fractions that have the qualities desired for further processing of the material. Solvent fractionation is a versatile method that produces a soluble and an insoluble fraction with varying compositions, including molecular weight distribution, polydispersity (PDI), and

Comparative Antioxidant Evaluation and GC-MS Identification of Bioactive Constituents in Litsea cubeba (Lour.) Pers. Fractions [PDF]

open access: yesMolecules
In this study, five solvent fractions from Litsea cubeba (Lour.) Pers. fruit were extracted and investigated for their antioxidant profiles. Results showed that the petroleum ether fraction (PEF) and n-butanol fraction (NBF) exhibited prominent free ...
