The brake wear contribution to the environmental pollution has been extensively discussed, with major focus on asbestos and heavy metals released to the environment. Only limited attention was paid to released organic compounds generated during friction processes, although the organic and carbonaceous components are not the minor part in brake lining formulations. Friction processes in brakes are associated with relatively high temperatures and high pressures on the friction surfaces which relates to the thermal decomposition of the organic components in friction materials and to brake lining thermal fade. Thus, this study focuses on the identification of organic compounds released from a model low metallic brake material. Several methods were used for the analysis: GC/MS screening of brake pad samples, brake wear debris and carbonaceous raw materials used in formulations of model pads; GC/MS screening of brake pad samples pyrolyzed at 300, 750, and 1000C, respectively, and FTIR analysis of brake pads and their wear debris. Higher quantity of organic compounds was identified in extract of the milled brake pad composite compared to the wear debris. More than 80 organic compounds were identified to be potentially released during braking. The major constituents were phenols, aliphatic and aromatic hydrocarbons, and their derivatives. Some of the identified compounds are known to have adverse effects even with mutagenic and carcinogenic potency to humans.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4265-25-2, and how the biochemistry of the body works.Electric Literature of 4265-25-2

Photochromic reaction behavior and thermal stability of thiophene-S,S-dioxidized diarylethenes having a benzofuryl group

Diarylethenes having a benzofuryl group and their thiophene-S,S-dioxidized diarylethenes were synthesized and their optical properties and thermal stability were investigated. Upon oxidation of the thiophene ring, the optical properties such as absorption maxima, photocycloreversion quantum yields, and conversion from the open-ring isomer to the closed-ring isomer have changed. On the other hand, the thermal stability of the closed-ring isomers of the S,S-dioxidized diarylethenes is significantly higher than those of thiophene-S,S-dioxidized diarylethenes having a phenylthienyl group instead of a benzofuryl group. The high thermal stability of the closed-ring isomer was quantitatively discussed based on ground state energies obtained by quantum chemical calculations.

Benzylic arylation of 2-methyl-5-membered heterocycles using TMP-bases

A new general Pd-catalyzed arylation of various 2-methyl-5-membered heterocycles is reported. This novel method requires Li-, Mg-, or Zn-TMP bases and allows selective metalation of the benzylic position. Subsequent Negishi cross-coupling provides the corresponding arylated heterocycles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 4265-25-2, you can also check out more blogs about4265-25-2

Structure of melanins from the fungi Ochroconis lascauxensis and Ochroconis anomala contaminating rock art in the Lascaux Cave

Two novel species of the fungal genus Ochroconis, O. lascauxensis and O. anomala have been isolated from the walls of the Lascaux Cave, France. The interest in these fungi and their melanins lies in the formation of black stains on the walls and rock art which threatens the integrity of the paintings. Here we report solid-state cross polarization magic-angle spinning 13C and 15N nuclear magnetic resonance (NMR) spectroscopy and surface-enhanced Raman spectroscopy (SERS) of the melanins extracted from the mycelia of O. lascauxensis and O. anomala in order to known their chemical structure. The melanins from these two species were compared with those from other fungi. The melanins from the Ochroconis species have similar SERS and 13C and 15N NMR spectra. Their chemical structures as suggested by the data are not related to 3,4-dihydroxyphenylalanine, 5,6-dihydroxyindole or 1,8-dihydroxynaphthalene precursors and likely the building blocks from the melanins have to be based on other phenols that react with the N-terminal amino acid of proteins. The analytical pyrolysis of the acid hydrolysed melanin from O. lascauxensis supports this assumption.

Fate of bisphenol A pyrolysates at low pyrolytic temperatures

Pyrolysis is an important method for breaking down organic waste to obtain useful low molecular weight compounds. To investigate the pyrolysis behavior of bisphenol A (BPA) and BPA pyrolysates at low pyrolytic temperatures, BPA and p-isopropenyl phenol (IPP) were pyrolyzed at 240?320?C using a batch reactor. BPA decomposition was strongly enhanced at temperatures higher than 240?C, and was almost complete after 30?min at 320?C. Theoretically, pyrolysis of BPA gives phenol (PhOH) and IPP in a 1:1 molar ratio, corresponding to yields of 41?wt% PhOH and 59?wt% IPP. However, an unexpectedly low IPP yield (?10?wt%) was obtained experientially, with a simultaneous increase in the yields of high molecular weight compounds. Compounds resulting from IPP polymerization were detected using electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS), suggesting that IPP was rapidly polymerized into high molecular weight compounds via radical propagation. On the other hand, a maximum PhOH yield of 62?wt% was obtained after 30?min at 320?C, which is higher than the theoretical yield. As direct dealkylation of IPP is difficult, the excess PhOH is likely derived from thermal decomposition of the IPP polymerization products. Thus, the present work revealed the high reactivity of IPP for polymerization at pyrolytic temperatures, which facilitates increased recovery of PhOH from BPA.

An overview of bio-oil upgrading with high hydrogen-containing feedstocks to produce transportation fuels: Chemistry, catalysts, and engineering

As an alternative to increasingly depleted traditional petroleum fuel, bio-oil has many advantages: high energy density, flexibility, easy storage and transportation. Nevertheless, bio-oil also presents some unwanted characteristics such as high viscosity, acidity, oxygen content and chemical instability. The process of bio-oil upgrading is necessary before utilization as transportation fuels. In addition, the bio-oil has low effective hydrogen/carbon molar ratio (H/Ceff) which may lead to coke formation and hence deactivation of the catalyst during the upgrading process. Therefore, it seemed that co-refining of biooil with other higher hydrogen-containing feedstocks is necessary. This paper provides a broad review of the bio-oil upgrading with high hydrogen-containing feedstocks to produce transportation fuels: chemistry, catalyst, and engineering research aspects were discussed. The different thermochemical conversion routes to produce bio-oil and its physical-chemical properties are discussed firstly. Then the bio-oil upgrading research using traditional technologies and common catalysts that emerged in recent years are briefly reviewed. Furthermore, the applications of high H/Ceff feedstock to produce high-quality of bio-oil are also discussed. Moreover, the emphasis is placed on co-refining technologies to produce transportation fuels. The processes of co-refining bio-oil and vacuum gas oil in fluid catalytic cracking (FCC) unit for transportation fuels from laboratory scale to pilot scale are also covered in this review. Co-refining technology makes it possible for commercial applications of bio-oil. Finally, some suggestions and prospects are put forward.

Effect of liquid smoking on lipid hydrolysis and oxidation reactions during in vitro gastrointestinal digestion of European sea bass

The effect of smoking using liquid smoke flavourings on the hydrolysis and oxidation of European sea bass lipids during in vitro digestion was investigated. The techniques used were 1H NMR and SPME-GC/MS. The former proved that liquid smoking does not influence the extent of lipolysis, but prevents those lipid oxidation reactions that occur during in vitro digestion of unsmoked samples, giving rise to cis,trans-conjugated dienes associated with hydroperoxy/hydroxy groups. SPME-GC/MS corroborated the results obtained by 1H NMR in relation to the antioxidant effect of smoking under gastrointestinal conditions. Smoked sea bass digests showed lower abundances of volatile oxidation markers derived from omega-3 and omega-6 lipids than unsmoked ones. Moreover, the lowest values were found in the digests of sea bass samples smoked with the flavouring showing the highest phenolic content. For the first time, the bioaccessibility of smoke flavouring components was evidenced, some of them well-known for displaying antioxidant activity.

Novel highly regioselective VO(acac)2/TBHP mediated oxidation of o-alkenyl phenols to o-hydroxybenzyl ketones

A novel mild methodology for the preparation of o-hydroxybenzyl ketones is described starting from o-alkenyl phenols and based on the VO(acac)2/TBHP (2 mol %/1.2 equiv) system. VO(acac)2 first catalyzes the epoxidation of o-alkenyl phenols and then the rearrangement of the epoxyphenols to ketones via the selective benzylic C-O cleavage and 1,2 hydride migration. The protocol has also been applied to set up a useful and easy one-pot conversion of o-alkenyl phenols to benzo[b]furans by means of the sequential addition of TFA, after the generation of the intermediate o-hydroxybenzyl ketones.

A light triggered optical and chiroptical switch based on a homochiral Eu2L3helicate

Optical and chiroptical photoswitches have found potential applications in advanced information technologies. Herein, a pair of chiral triple-stranded helicates [Eu2(o-LRR)3](TOf)6and [Eu2(o-LSS)3](TOf)6, which have chirality, luminescence and light stimuli-responsive properties, have been designed and synthesized. The ligands o-LRR/SSare composed of photochromic diarylethene moieties as spacers and two chiral 2,6-dipicolinic amides as coordination units. Through the comprehensive spectral characteristics in combination with semiempirical geometry optimization using the Sparkle/RM1 model, it was confirmed that (R/S)-1-phenylethanamines decorated at the terminals of ligands successfully controlled the stereoselective self-assembly of the helicates. Upon alternating UV and visible light irradiation, the diarylethene experienced a reversible change between a colorless open-ring state and a pink closed-ring state. This photochromic process caused variations in the electronic structure and ligand conformation, and led to the presence of light-responsive optical (UV and PL) and chiroptical (ECD and CPL) switching properties. The helicate may, therefore, be considered as a completely reversible +/- ECD and on/off CPL switch. Furthermore, on the basis of these light-switchable optical properties, the INHIBIT and IMPLICATION logic gates were fabricated.
