Levels Of 5-hydroxymethylfurfural in dextrose injection
American Journal of Health-System Pharmacy, 1977The levels of the degradation product, 5-hydroxymethylfurfural (5-HMF), in Dextrose Injection USP were determined by spectrophotometry. A freshly prepared solution of dextrose (1 g/2 ml) had a 5-HMF level of 0.10 mug/ml. The level in 50% dextrose injection, within 24 hours of manufacturing, was 0.72 mug/ml. The level of 5-HMF in 50% dextrose injection,

Fluorometric measurement of furfural and 5-hydroxymethylfurfural
Analytical Biochemistry, 1982Abstract Zine(II) forms highly fluorescent chelates with the aroyl hydrazones of furfural and 5-hydroxymethylfurfural, with the latter being more fluorescent than the former. The choice of aromatic acid hydrazide (aroyl hydrazine) as analytical reagents for furfurals was examined; 4-toluenesulfonic acid hydrazine was the most sensitive reagent ...

A review of 5-hydroxymethylfurfural (HMF) in parenteral solutions
Fundamental and Applied Toxicology, 1984The chemical formation, toxicity, and pharmacokinetics of 5-hydroxymethylfurfural (HMF) and certain other decomposition products found in parenteral solutions are reviewed. Heat sterilization-induced hexose decomposition to furan derivatives is promoted at low pH.

Hydrolysis of Glucose to 5-Hydroxymethylfurfural
Advanced Materials Research, 2011We used solid acid and solid base we made ourselves prepared 5-hydroxymethylfurfural (5-HMF) from glucose. Researched on the effects of quality ratio of solid acid and solid base, substrate concentration, volume ratio of two phases, reaction temperature and reaction time on 5-HMF yield. Results were shown that the conditions quality ratio of solid acid

Electrocatalytic Hydrogenation of 5‐Hydroxymethylfurfural in Acidic Solution
ChemSusChem, 2015AbstractElectrocatalytic hydrogenation of 5‐hydroxymethylfurfural (HMF) is studied on solid metal electrodes in acidic solution (0.5 M H2SO4) by correlating voltammetry with on‐line HPLC product analysis. Three soluble products from HMF hydrogenation are distinguished: 2,5‐dihydroxymethylfuran (DHMF), 2,5‐dihydroxymethyltetrahydrofuran (DHMTHF), and 2 ...

Synthesis of 5-Hydroxymethylfurfural-Acetone Resins
Key Engineering Materials, 20215-hydroxymethylfurfural-acetone (5-HMFA) resins are obtained on the basis of 5-hydroxymethylfurfural (5-HMF) and acetone, that is, from monomers whose source of raw materials is renewable resources (agricultural waste). The 5-HMFA condensation reaction was carried out under various experimental conditions.

Degradation of 5-hydroxymethylfurfural during yeast fermentation
Food Additives & Contaminants: Part A, 20115-Hydroxymethyl furfural (HMF) may occur in malt in high quantities depending on roasting conditions. However, the HMF content of different types of beers is relatively low, indicating its potential for degradation during fermentation. This study investigates the degradation kinetics of HMF in wort during fermentation by Saccharomyces cerevisiae.
