The antifungal effect of pine needle extract prepared by a distinguishable extraction method and the dry distillation method, was examined. The effect of this extract itself was insignificant. The chemical components of pine needle extract were then investigated by gas chromatographic analysis, and four chemical components, acetol, furfural, 5-methyl furfural, and terpine-4-ol, were identified....

Furfural is being added to kerosene to check the adulteration of gasoline/high speed diesel oil. The possibility of a co-exposure of furfural and kerosene and the ability to exhibit the toxic effects of such a mixture were examined in view of the toxicity potential of the two alone and in combination with each other. A single inhalation exposure of rats to furfural was fully tolerated up to a c...

Every year, millions of tons food and beverage waste are thrown away unused around the world. The carbohydrates found in create a raw material potential for production high value-added products that used energy, feed pharmacology. One these products, 5-Hydroxymethyl-2-furfural (5-HMF), is by-product simple dehydration carbohydrates. It finds wide use field pharmacy due to its anticancer, antifu...

Electrochemical conversion of biomass-derived 5-hydroxymethyl-furfural (HMF) to 2,5-furandicarboxylic acid (FDCA), the building block bio-based plastics, is an attractive process that leverages renewable electrons and carbon resources. The offers potential increase energy cost efficiency by combining mild reaction conditions with high activity selectivity. This study elucidates mechanism kineti...

effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. lungmuir, frumkin and flory-huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

Two gas chromatography extraction methods based on liquid-liquid (LLE) and headspace solid phase microextraction (HS-SPME) were evaluated for analysis of furfural from hemicellulose hydrolysates. Woody biomass was used as renewable resource for furfural production. In this study, autohydrolysis pretreatment was investigated for conversion of xylose and arabinose into furfural at selected ranges...

The tunable transformation of renewable furfural with aliphatic alcohols in the presence of O2 is developed. Based on a nano Au catalyst and potassium carbonate, a 91.8% yield of methyl 2-furoate with 98.7% selectivity is obtained via the oxidative esterification in a furfural-methanol-O2 system; while a 91.4% yield of 3-(furan-2-yl-)-2-methylacrylaldehyde with 97.2% selectivity is attained via...

Background: Pekmez is an important fruit-based food of Turkish culinary culture. The aim of this study is to determine the levels of acrylamide (AA), 5-hydroxymethyl-2-furfural (HMF) and other selected parameters in grape, mulberry and carob Pekmez. Methods: AA and HMF were analyzed by Liquid Chromatography and High Performance Liquid Chromatography, respectively. Also, glucose, fructose, pH, ...
