MULTIFUNCTIONALIZATION OF CELLULOSE MICROFIBRILS THROUGH A CASCADE PATHWAY ENTAILING THE SUSTAINABLE PASSERINI MULTI-COMPONENT REACTION

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 01 ottobre 2020 Through a cascade of chemical derivatizations involving the green Passerini three-component reaction (P-3CR), we describe herein the multifunctionnalization of cellulose microfibrils (MFC) previously subjected to a periodate oxidation step. Not only do MFC constitute a remarkably attractive cellulose substrate from industrial......

UNDERSTANDING THE IN-SITU STATE OF LIGNOCELLULOSIC BIOMASS DURING IONIC LIQUIDS-BASED ENGINEERING OF RENEWABLE MATERIALS AND CHEMICALS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 25 settembre 2020 Ionic liquids (ILs) can be used to sustainably convert lignocellulosic feedstocks into renewable bio-based materials and chemicals. To improve the prospects of commercialization, it is essential to investigate the fate of lignocellulosic biomass during IL-based processing and develop tools for designing......

PRODUCTION OF SUSTAINABLE AND RENEWABLE BIOMASS-DERIVED MONOMER: CONCEPTUAL PROCESS DESIGN AND TECHNO-ECONOMIC ANALYSIS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 21 settembre 2020 2,5-Furandicarboxylic acid (FDCA) is a promising renewable building block, which can replace conventional petroleum-derived terephthalic acid (TPA). Here, we develop and evaluate a new catalytic process for the production of renewable plastic monomer (FDCA) from lignocellulosic biomass-derived cellulose. In this process,......

EFFICIENT CONVERSION OF CELLULOSE TO 5-HYDROXYMETHYLFURFURAL CATALYZED BY A COBALT-PHOSPHONATE CATALYST

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 17 settembre 2020 A heterogeneous cobalt-phosphonate network catalyst, [Co2(2,2′-bipy)(H4L)(H2O)]H2O (Co318), was synthesized by hydrothermal reaction. The combination of Brønsted acid (-PO3H2) and Lewis acid sites (Co2+) makes Co318 an efficient catalyst for the conversion of saccharides to HMF. Under optimized conditions, glucose was quantitatively......

EFFECT OF CATION STRUCTURE ON THE CELLULOSE DISSOLUTION IN AQUEOUS SOLUTIONS OF ORGANIC ONIUM HYDROXIDES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 09 settembre 2020 Solubility of cellulose was systematically assessed in organic onium/inium hydroxide aqueous solutions (OHAS) employing assorted cations, such as phosphonium, ammonium, piperidinium, morpholinium, pyrrolidinium, and cholinium cations. From a dissolution test of cellulose in the OHAS, it was confirmed that the single......

PATIENCE IS A VIRTUE: SELF-ASSEMBLY AND PHYSICO-CHEMICAL PROPERTIES OF CELLULOSE NANOCRYSTAL ALLOMORPHS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 11 agosto 2020 Cellulose nanocrystals (CNCs) are bio-based rod-like nanoparticles with a quickly expanding market. Despite the fact that a variety of production routes and starting cellulose sources are employed, all industrially produced CNCs consist of cellulose I (CNC-I), the native crystalline allomorph of......

UNDERSTANDING THE EFFICIENCY OF IONIC LIQUIDS-DMSO AS SOLVENTS FOR CARBOHYDRATES: USE OF SOLVATOCHROMIC- AND RELATED PHYSICOCHEMICAL PROPERTIES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 29 luglio 2020 The physical dissolution of carbohydrates (cellulose, chitin, and starch), i.e., without formation of covalent bonds requires that the solvent possess certain physicochemical properties. Concentrating on cellulose, the solvent should act both as Lewis acid, and Lewis base, and disrupt the present......
