One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Safety of 2-Methylbenzofuran, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O

A hydrodeoxygenation reaction (HDO) of bio-oil was conducted with Ru/C and Pt/C. Yield of heavy oil as a target product was influenced by reaction temperature irrespective of catalysts. HDO gave rise to an improvement in the following oil properties: water content, heating value, viscosity, acidity and oxygen level. Due to the de-moisturization, 61.6-97.2% of water decreased. Ru/C and Pt/C led to deoxygenation with increasing temperature. Especially, the heavy oil obtained from 350 C with Pt/C was deoxygenated up to 78.2% and had a higher heating value (27.8 MJ/kg) than the bio-oil (17.3 MJ/kg). After HDO unstable/unsaturated compounds (acetic acid, furfural, vanillin and levoglucosan) in bio-oil were converted to esters, ketones and saturated phenols. According to the reusability test of HDO catalysts chars were deposited on the surface of catalysts, which could be the reason for the deactivation of catalysts. The Pt/C was denoted as having high durability and thermal resistance

Related Products of 4265-25-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O.

The catalytic fast pyrolysis of oak over two zeolites (microporous and hierarchical) was investigated in a microfluidized bed reactor (MFBR) at 500 C and as a function of the biomass-to-catalyst ratio. A hierarchical zeolite was produced by desilication with a NaOH solution of a conventional HZSM-5 zeolite. The outlet of the MFBR was connected to a single photoionization mass spectrometer (SPI-MS) for the on-line analysis of volatiles. This on-line analysis method allows studying the dynamics of volatile formation (in real time) and the deactivation of 2 zeolites upon stepwise injections of wood particles. Strikingly, the selectivity of targeted mono-aromatic compounds (quantified by gas chromatography) is doubled after desilication of the zeolite. The coked zeolites were characterized by TEM-EDX, digestion in fluoric acid, MALDI-TOF MS, etc. Three different types of coke are evidenced: (1) coke trapped inside micropores, (2) external coke formed on the outer surface of the crystals and (3) coke precursors deposited in the mesopores. The latter two cokes are much less toxic than the microporous coke. The open mesopores produced after desilication can be seen as “highways” where big molecules (such as levoglucosan) can diffuse to more accessible pore mouths. Br°nsted acid sites present on microporous mouths can be active for the conversion of bigger molecules to small fragments. These fragments diffuse and form aromatics in the micropores (shape selectivity). The mesopores also promote the evacuation of catalytic products, thus enhancing the selectivity of mono-aromatic hydrocarbons. Desilicated zeolites present higher selectivity to mono-aromatics and stability upon coke deposition than microporous zeolites.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C9H8O, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4265-25-2, name is 2-Methylbenzofuran.

Flash vacuum pyrolysis of 2-allyloxypropenoic esters (e.g. 7) gives benzo[b]furans (e.g. 32) in synthetically useful yields by sequential generation of a phenoxyl radical, cyclisation and ejection of the carboxylic ester function as a free radical leaving group. The method is compatible with a range of substituents on either the benzene ring or the propenoate chain, and is particularly effective for 2-substituted benzo[b]furans. The natural products 5-methoxybenzo[b]furan 1 and angelicin 2 have been synthesised in three and four steps respectively from commercially available starting materials by this route. Related cyclisations to give naphtho[2,1-b]furan 40 were complicated by competitive formation of naphtho[2,1-b]pyran-3-ones (e.g. 41 and 42), but the yield of the required product could be optimised by the choice of the radical precursor. Annelation of a furan ring onto a thlophene is also possible by this method, but lower yields are obtained in such pyrolyses.

A model used to predict equilibrium adsorption to surfaces using a poly-parameter linear free-energy relationship as well as an empirical model used to predict enthalpies of adsorption of volatile compounds were evaluated with new experimental data to cover semivolatile compounds and a larger variability of compound classes. Equilibrium adsorption constants on a quartz surface ranging over seven orders of magnitude were measured for 142 compounds, and enthalpies of adsorption on a quartz surface from -33.7 to -99.8 kJ/mol were measured for 76 compounds. Agreement between experimental and predicted data was within a factor of two (82.1%) or three (100.0%) for the equilibrium adsorption constants and within 20% for the enthalpy of adsorption values. Thus, the scatter in the validation data sets reported here were practically the same as that for the calibration data sets used to derive the models. The few outliers that we identified in the prediction of equilibrium adsorption constants likely are caused by either shortcomings of the reported sorbate parameters or the occurrence of chemical speciation in the water layer on the surface of the quartz.

The establishment of permanent fish cell cultures dates back in the early 1960s and since then more than 283 fish cell lines have been developed. The cells were isolated from a broad range of tissues such as ovary, fin, swim bladder, heart, spleen, liver, eye muscle, vertebrae, brain, skin and especially embryos from different fish species. In contrast to mammals, fish cell lines are derived from normal tissues, with only a few exceptions isolated from epithelioma or hepatoma Cultured fish cells were used for genotoxicity assessment for the first time in 1979,2 when transformed cells derived from a primary culture of embryonic tissue of butterfly splitfin (Ameca splendens) were used for the evaluation of the induction of sister chromatid exchanges (SCEs) by carcinogens/mutagens. Since then, a variety of different fish cell lines have been successfully introduced for the detection of a large variety of genotoxic endpoints. As most fish karyotypes consist of large numbers of small, irregular chromosomes, chromosomal aberrations (CA), which are usually detected in metaphase-blocked cells, are difficult to discern and to interpret in fish cells, thus the analysis is complicated and time-consuming. Therefore, other methods such as micronucleus assay are recommended for the assessment of chromosomal damage instead of SCE and CA in fish cells (Figure 13.1).

The combustion of biomass in boilers of emission classes 2 and 3 produces deposits in the form of char and soot inside the combustion chamber. Char and soot differ in content of elemental carbon (EC) and organic carbon (OC) as well as in the content of organic compounds. Deposits from boilers of emission class 2 contain higher amounts of OC and EC than those from boilers of emission class 3. The only exception is deposits formed by the combustion of briquettes from hardwood in boilers of emission class 3 that contained approximately by up to 60 percent higher amount of OC and by approx. 100% more EC than deposits from combustion in boilers of emission class 2. Deposits identified as char are characterized by dominant organic compounds derived from thermic degradation of cellulose, lignin, phytosterols, terpenes, their alteration products, and aromatic hydrocarbons. Deposits identified as soot have dominant PAHs, compounds containing oxygen (furans, benzofurans, phenols) and compounds containing aliphatic nitrogen (benzonitrile). Char from boilers of emission class 2 contains approx. by 80% more alkanes and cycloalkanes, by 80% more nitriles, by 50% more carboxyl acids, by 230% more anhydrosaccharides, phytosterols and by 180% more PAHs. These differences can be utilized for identification of burned fuel.

Phenyl allenyl ethers undergo Claisen rearrangement under electron impact conditions producing intense ions.Another competing fragmentation pathway in these compounds is an intramolecular aromatic substitution followed by the loss of H or the substituent to give rise to fragments corresponding to benzopyrilium cations.Electron-withdrawing substituents on the phenyl ring favour the cyclization reaction.An interesting ortho interaction of the nitro group with the allenic moiety leads to the expulsion of CO2 from the molecular ion.The proposed fragmentation pathways and the ion structures are established with the help of linked-scan spectra (B/E, B2/E), collision activation decomposition spectra and high-resolution data.

The soil memory recorded in paleosols of loess-paleosol sequences is an important contributor to our understanding of past climatic conditions. Molecular proxies based on the organic matter preserved in paleosols form an essential part of this record, but the long-term preservation of SOM is poorly understood, especially for sediment traps and slope profiles. This paper addresses the composition of organic material from the Early Weichselian A-horizons of the Rocourt paleosol, a major paleostratigraphic marker for the Eemian and Early Weichselian in Western Europe. NaOH-extractable organic matter from an exceptionally thick Rocourt profile in the Kesselt Quarry (Belgian Loess Belt) was analyzed by pyrolysis-Gas Chromatography/Mass Spectrometry (pyrolysis-GC/MS) and the results evaluated against paleopedological data. The molecular composition of the organic matter at Kesselt was compared with reference samples from two nearby quarries (including the type locality at Veldwezelt-Hezerwater), and to a sample from the contemporary Nussloch sequence in Germany. The SOM composition found at the four sites indicated a large content of microbial matter and was dominated by carbohydrates and N compounds, many of which were not reported before from SOM pyrolysates. Differences in the molecular composition between samples, both within profiles and between sites, coincided with differences in landscape position (slope-shoulder-plateau) and fossil redox conditions (surface gleys). Samples form drier and more upland situations contained more burnt material, while samples from slope profiles and surface gleys contained even more microbial material, in particular chitin. Results therefore suggest that the admixture of microbial SOM is considerable in loess-paleosols and that differences in edaphic conditions (in particular slope position and soil moisture) and occurrence of wildfires are important for the long-term preservation of SOM. These should therefore be considered when interpreting biogeochemical proxies.

Six samples, including wood and jet-like material from the same mummified wood specimens, together with two ‘true’ jet samples, were studied using pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) to obtain detailed insight into the process leading to the formation of jet. Based on morphological and chemical data obtained, the process of “jetification” is characterised by a rapid change when mummified wood is re-exposed to sunlight and aerobic conditions. The transformation from mummified wood to jet is probably caused by relatively small chemical changes, leading to extra linkages between the phenolic compounds and causing the structure to become much more rigid, which is reflected in increased inertness of the material at the macroscopic level.
