The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

Chemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

BioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...
