要旨

Valorization of technical lignin is crucial for the circular bioeconomy – this can be achieved by the transformation of lignin to high-value nanomaterials. However, the majority of lignin nanoparticle (LNP) production methods require high volumes of organic solvent, and specialized equipment, or fail in certain cases to produce a morphologically uniform product with superior physicochemical properties to technical lignin. Herein, a binary solvent system of subcritical water and acetone based on the principles of solvent–antisolvent (SAS) precipitation of lignin is proposed. Spherical LNPs with a high degree of uniformity in the chemical structure are produced via a batch reactor from kraft lignin demonstrating high yield (88–92%), colloidal stability in water, thermal stability, and low mean particle size – these are desirable for advanced biocomposite and biomedical applications; achieved in this study by using lower volumes of recyclable acetone (4–7 times less) than previously reported.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
