2016 journal article

Ionic Liquid Character of Zinc Chloride Hydrates Define Solvent Characteristics that Afford the Solubility of Cellulose

The Journal of Physical Chemistry B, 120(6), 1134–1141.

By: S. Sen n, B. Losey n, E. Gordon n, D. Argyropoulos n  & J. Martin n 

Contributors: S. Sen n, B. Losey n, E. Gordon n, D. Argyropoulos n  & J. Martin n 

MeSH headings : Cellulose / chemistry; Chlorides / chemistry; Ionic Liquids / chemistry; Molecular Conformation; Solubility; Solvents / chemistry; Water / chemistry; Zinc Compounds / chemistry
TL;DR: Neutron diffraction and differential pair distribution function analysis of cellulose and model compound solutions suggest that cellulose solubility occurs via coordination of the primary OH to the hydrated zinc cation with ring hydroxyls forming part of a second coordination shell around the cation of the ionic liquid.

Kraft Lignin Chain Extension Chemistry via Propargylation, Oxidative Coupling, and Claisen Rearrangement

BIOMACROMOLECULES, 14(10), 3399–3408.

MeSH headings : Lignin / chemical synthesis; Lignin / chemistry; Methylation; Molecular Structure; Molecular Weight; Oxidation-Reduction; Pargyline / analogs & derivatives; Pargyline / chemistry; Polymerization; Polymers / chemical synthesis; Polymers / chemistry; Temperature
TL;DR: It is shown that it is possible to modulate the reactivity of softwood kraft lignin via a combination of methylation and chain extension providing a rational means for the creation of higher molecular weight polymers with the potential for thermoplastic materials and carbon fibers with the desired control of structure-property relations.
