In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 24673-56-1, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 24673-56-1, name is 3-Methylbenzofuran-2-carboxylic acid. In an article，Which mentioned a new discovery about 24673-56-1

Metal-catalyzed cycloisomerization reactions of 1,n-enynes have become conceptually and chemically attractive processes in the search for atom economy, which is a key subject of current research. However, metal-catalyzed cycloisomerization between aryl enol ether and silylalkynes has not been developed. The ruthenium hydride complex catalyzed cycloisomerization between aryl enol ether and silylalkynes is reported to give benzofurans having useful functional groups, vinyl and trimethylsilylmethyl, on the 2- and 3-positions, respectively.

496-41-3, Name is Benzofuran-2-carboxylic acid, belongs to benzofurans compound, is a common compound. Application In Synthesis of Benzofuran-2-carboxylic acidIn an article, once mentioned the new application about 496-41-3.

Benzo- and naphthofuran carboxylates 1, 2 and carboxamides 3, 4 were synthesized and pyrolysed by flash vacuum pyrolysis at 550 and 650 C/10?2 mmHg. 2-Formylbenzonitrile 7 from benzofurans and 2-formylnaphthonitrile 14 from naphthofurans were isolated and identified as major products. The mechanism suggested for these pyrolytic reactions involves elimination of alcohol and amine from carboxylates 1, 2 and carboxamides 3, 4 respectively, followed by extrusion of CO to form phenoxy and naphthoxycarbenes that leads to 7 and 14 respectively.

An optical system for the measurement of pH value of foods during its high-pressure treatment was developed. The principle is an absorption measurement using indicator dyes. An indicator mix of 16 different pH-sensitive substances is used to cover the pH range of food. To manage the difficult spectra, a multivariate approach is used. The calibration of the system is performed by taking five different buffer solutions with known pressure behavior (TRIS, CAPS, citric, phosphoric, and acetic acid buffers). The corresponding spectra of the indicator mix are measured and fed to a multivariate data model together with calculated pH values. Some chemometric models have been tested to estimate the pH value based upon the spectra of the indicator mix. The calibration device covers a pH range from 2 to 8 at ambient pressure. After calibration, the system is able to determine the pH value at pressures of up to 450 MPa with an accuracy of 0.24 pH units using eight different test media.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Application of 1563-38-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, molecular formula is C10H12O2. In a Article，once mentioned of 1563-38-8

This paper describes a fluorescence detection method for N- methylcarbamate (NMC) pesticides in micellar electrokinetic chromatography (MEKC) separation. Fulfillment of the fluorescence detection hinged on the discovery that quaternary ammonium surfactants (particularly cetyltrimethylammonium bromide, CTAB), besides serving as hydrophobic pseudophases in MEKC, are also capable of catalyzing the thermal decomposition of NMCs to liberate methylamine. Thus, a multifunctional MEKC medium consisting of borate buffer, CTAB, and derivatizing components (o- phthaldialdehyde/2-mercaptoethanol) was formulated, which allowed first normal MEKC separation, subsequent thermal decomposition, and finally in situ derivatization of NMCs. With careful optimization of the operation conditions, fluorescence detection of 10 NMC compounds was achieved, with column efficiencies typically higher than 50 000 and detection limits better than 0.5 ppm. The present work represents an unprecedented effort in capillary electrophoresis (CE), in which an intact capillary was consecutively utilized as chambers for separation, decomposition, derivatization, and detection, without involving any interfacing features. The success in the implementation of such a detection system resulted in strikingly simple instrumentation as compared with the traditional postcolumn fluorescence determination of NMCs by reversed-phase HPLC. Similar protocols should be workable in the determination of a wide range of pesticides and pharmaceuticals in CE formats.
