Carbohydrates as a component in adhesive formulations have been reported for many years. A rapid cure at moderate temperatures is remaining challenge the development of renewable adhesives. Rheology provides insight into all stages structure formation cured polymer. This work analyses curing carbohydrate-amine adhesives with and without addition 5-hydroxymethylfurfural (HMF) biomass-derived key...
The implementation of cost-effective and sustainable biorefineries to substitute the petroleum-based economy is dependent on coupling production bioenergy with high-value chemicals. For this purpose, US Department Energy identified a group key target compounds be produced from renewable biomass. Among them, 5-hydroxymethylfurfural (HMF) can obtained by dehydration hexoses present in biomass an ...
Based on Transcarpathian zeolite the catalysts in calcium-lanthanum-ammonium form were synthesized and modified by steaming dealumination with ethylenediaminetetraacetic acid. The samples characterized using nitrogen adsorption/desorption, XRD, XRF, FTIR-spectroscopy. yield of 5 hydroxymethylfurfural over at 433 K was found to be 50 83% a practically full conversion fructose.
In the present study, the physicochemical properties and antioxidant activities of different Iranian honey samples are investigated using various multivariate techniques in order to develop a quality control model. Forty-eight Iranian honey samples were tested for 15 physicochemical and antioxidant parameters. The parameters for which the samples were tested included color intensity, moisture, ...
