The initial steps in the thermal decomposition of 2,5-dimethylfuran are identified as scission of the C-H bond in the methyl side chain and formation of β- and α-carbenes via 3,2-H and 2,3-methyl sh...Read More
Kinetics of the reactions of OH radicals with 2- and 3-methylfuran, 2,3- and 2,5-dimethylfuran, and E- and Z-3-hexene-2,5-dione, and products of OH + 2,5-dimethylfuran.
Furan and alkylfurans are present in the atmosphere from direct emissions and in situ formation from other volatile organic compounds. The OH radical-initiated reactions of furan and alkylfurans have ...Read More
A high-level ab initio thermochemical technique, known as the Feller-Petersen-Dixon method, is used to calculate the total atomization energies and hence the enthalpies of formation of 2,5-dimethylfur...Read More
A mixture of tautomers with unique keto-enol structures, 5-ethyl-4-hydroxy-2-methylfuran-3(2H)-one and 2-ethyl-4-hydroxy-5-methylfuran-3(2H)-one (EHMF, homofuraneol, 1a and 1b), comprises four structu...Read More
Density functional theory and RRKM calculations of the gas-phase unimolecular rearrangements of methylfuran and pyran ions before fragmentations.
The potential energy profiles for the mutual conversion of the isomeric molecular ions [C(5)H(6)O](+*) of 2-methylfuran, 3-methylfuran and 4H-pyran and the fragmentations that lead to [C(5)H(5)O](+) i...Read More
Previous model studies have suggested ascorbic acid as one of the major sources of furan, a possibly hazardous compound found in thermally processed foods (e.g. canned products, jars). The study showe...Read More
An important mechanism of toxicity of furans involves the cytochrome P-450 monooxygenase-catalyzed bioactivation of the compound in situ directly within the target tissues to highly reactive electroph...Read More
[Radio-protective effect of sulfur-containing methylfuran derivatives and the role of thiols in its realization].
In experiments on mice it was demonstrated that S-containing methylfuran derivatives were highly radioprotective (50-70% survival of exposed animals). The preparations under study did not influence th...Read More
Hydroxyalkylation-alkylation (HAA) coupled with hydrodeoxygenation is a promising route for the synthesis of renewable high-quality diesel or jet fuel. In this work, a series of solid-acid catalysts w...Read More
Quantitative analysis of volatiles from solid matrices of vegetable origin by high concentration capacity headspace techniques: Determination of furan in roasted coffee
The study compares standard addition (SA), stable isotope dilution assay (SIDA) and multiple headspace extraction (MHE) as methods to quantify furan and 2-methyl-furan in roasted coffee with HS-SPME-G...Read More
Development of accurate classification method based on the analysis of volatile organic compounds from human exhaled air
Analysis of exhaled air leads to the development of fast accurate and non-invasive diagnostics. A comprehensive analysis of the entire range of volatile organic compounds (VOCs) in exhaled air samples...Read More
Quality and flavour stability of coffee substitute prepared by extrusion of wheat germ and chicory roots.
A mixture of roasted chicory roots and wheat germ (1:1 w/w) was subjected to extrusion processing for preparation of coffee substitute. Comparative studies concerning sensory characteristics and heads...Read More
The synthesis of new 2-methylfuran-based alcohols is described. The odor and physicochemical characteristics of all new compounds are also presented....Read More
2-Methylfuran (2-MF), a constituent of cigarette smoke and coffee, causes necrosis of liver, lungs, and kidneys in rodents. 2-MF is metabolically activated by mixed-function oxidases to acetylacrolein...Read More
Administration of a single ip dose of 2-methylfuran (2-MF) to male Sprague-Dawley rats at a dose of 100 mg/kg produced centrilobular necrosis of the liver and bronchial injury of the lung, the severit...Read More
Treatment of male Sprague-Dawley rats with buthionine sulfoximine (BSO), prior to administration of carbon-14(14C)-labelled 2-methylfuran (2MF) caused a marked decrease in the covalent binding of 14C-...Read More
A set of six espresso coffees with different foam characteristics and similar above cup and in-mouth flavour sensory profiles was produced by combination of two varying parameters, the extraction pres...Read More
