Chemistry is traditionally divided into organic and inorganic chemistry. category: benzofuran, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 41717-32-2

An efficient method for the Beckmann rearrangement of ketoximes to amides mediated by a catalytic amount (15 mol %) of propylphosphonic anhydride (T3P) is described. Aldoximes underwent second order Beckmann rearrangement to provide the corresponding nitriles in excellent yields on reacting with T3P (15 mol %) at room temperature. The main advantages of this environmentally friendly protocol include procedural simplicity, and particularly ease of isolation of the products.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C10H8O3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 24673-56-1, Name is 3-Methylbenzofuran-2-carboxylic acid, molecular formula is C10H8O3

A new thiadiazole ligand, N-ethyl-5- (benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine (BTH), was prepared from 3-methyl-1-benzofuran-2-carboxylic acid and N-ethylhydrazinecarbothioamide precursors. Corresponding silver(I) complex, tetrakis(N-ethyl-5-(benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine)silver(I) nitrate [Ag2(BTH)4](NO3)2 (1), was prepared. The structures of BTH and 1 were characterized by 1H-NMR, 13C-NMR, FT-IR, elemental analysis and HR-MS techniques. Furthermore, molecular structure of 1 was illuminated by X-ray crystallography. Owing to strong anagsotic interaction, crystal structure of the complex revealed an intriguing asymmetric monomer unit even with two same ligands in 2:1 metal-to-ligand stoichiometry. Photoluminescence properties of the complex were investigated by solid and solution media emission measurements. Excited and emissive state behavior of the complex was further analyzed by quantum chemical TD-DFT calculations and natural transition orbital (NTO) analyses.

Related Products of 4265-25-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4265-25-2, 2-Methylbenzofuran, introducing its new discovery.

The lighter density (<1.5 g/cm3) fractions produced from two waste coals sampled from the waste coal disposal sites at thermochemical plants situated in South Africa were used as feed materials for liquefaction with tetralin. The liquefaction residues from the lighter density and untreated lighter density fractions were used in pyrolysis experiments. Pyrolysis of the lighter density fractions was carried out in a Fischer Assay oven at 750 and 920 C under an argon atmosphere. Advanced analytical techniques (gas chromatography-mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy) were employed to characterize the pyrolysis products. Also, the lighter density fractions, liquefaction residues, and their chars were examined using conventional and advanced analytical techniques. The pyrolysis char yields of the liquefaction residues ranged between 74% and 76%, and those of the coal float fractions ranged between 67.0 and 71.5%. Gas pyrolysis yields ranged between 16.0% and 20.0% for the residues and between 14.5% and 18.4% for the lighter density fractions, while the pyrolytic water and the tar products of the lighter density fractions were slightly higher than those of the liquefaction-derived residues. The proton NMR analysis of the tars from the residues shows marginally higher amounts of aromatic protons than those of the lighter density fractions. Chars which were generated after pyrolysis of the liquefaction-derived residues show higher porosity values than those from the pyrolysis of the lighter density fractions. The differences in the porosities are attributed to the opening of pores and extraction of some lower molecular mass aliphatic species from the coal matrix during liquefaction. The pyrolysis products distribution and characterization of the products showed that the residues (waste material) generated after tetralin liquefaction of the float fractions from the float-sink experiments of waste coals may be utilized for thermochemical processes (pyrolysis).
