Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article investigates the conversion of cellulose to 5-hydroxymethylfurfural (HMF), a valuable biomass-derived intermediate, using mixed acid catalysis. It highlights the importance of optimizing reaction conditions, including solvent systems, catalyst types, and substrate concentrations, to enhance HMF yield and selectivity. The study reveals that a combination of H2SO4 and Al2(SO4)3 in a THF/water system achieves an optimal HMF yield of 46.5%, outperforming single acid systems. The kinetic analysis demonstrates that the mixed acid system significantly reduces the activation energy for key reaction steps, facilitating efficient cellulose conversion even at high substrate loadings. Additionally, the article presents a novel purification method using NaHSO3 and 2-MTHF, achieving high HMF purity and solvent recyclability, which is crucial for industrial-scale production. The findings underscore the potential of using inexpensive commercial catalysts for sustainable and cost-effective HMF production from lignocellulosic biomass.
