Polycyclic aromatic hydrocarbons (PAH) are refractory structures common in heavy hydrocarbons. Thermal cracking in supercritical water (SCW) is limited but PAH can be completely oxidised if an oxidant is added. By restricting oxidant supply to substoichiometric amounts, this study aims to achieve partial oxidation as a route to useful chemicals, such as mono- and bi-aromatics. Oxidative cracking reactions of anthracene, pyrene and benzo[a]pyrene in subcritical and SCW were studied. PAH conversions well above 90 % were achieved along a fast heating ramp in a batch reactor. This quick initial oxidation took place predominantly in inner rings, weakening the aromatic structure and increasing cracking reactivity. This oxidation-cracking pathway became dominant in the SCW region, producing mostly oxygenated compounds with fewer aromatic rings. On the other hand, competing reactions leading to polymerization were favoured in the subcritical water region. PAH reactivity was found to follow the order anthracene > benzo[a]pyrene > pyrene.

I found the field of Environmental Sciences & Ecology very interesting. Saw the article Occurrence of persistent organic pollutants in air at different sites in the province of Cordoba, Argentina published in 2019.0. Category: ethers-buliding-blocks, Reprint Addresses Pegoraro, CN (corresponding author), Univ Nacl Mar del Plata, CONICET, Fac Ciencias Exactas & Nat, Dept Quim, Mar Del Plata, Buenos Aires, Argentina.. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide

The occurrence of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in the atmosphere of six sites with different emission sources in the province of Cordoba, Argentina, was analyzed. The sites included urban, industrial, agricultural, and mountain areas. Samples were collected using passive air samplers (PAS) consisting of polyurethane foam disks (PUF). Samples were analyzed for 12 PAHs, 31 polychlorinated biphenyls (PCBs), 12 organochlorine pesticides (OCPs), and 11 polybrominated diphenyl ethers (PBDEs). The concentrations of PAHs in the atmosphere were elevated at urban sites and were even higher at the industrial site. With respect to OCPs, it was observed that the concentrations of endosulfan were greater at the agricultural site (AGR) (416 +/- 4pgm(-3)). For hexachlorocyclohexanes (HCHs), only the alpha isomer was detected and there were minimal differences between the different sampling sites (5.9-13.3pgm(-3)). In the case of dieldrin, the highest concentrations (33.6pgm(-3)) were found at the mountain site, which may have been due to its use for insect control. Although heptachlor epoxide was not detected, the concentration of heptachlor was significantly higher at the agricultural and downtown sites (approximate to 3.6pgm(-3)). Regarding DDTs, the isomers p,p-DDT and p,p-DDE showed the highest concentrations at the mountain site (sigma DDT 120 +/- 12pgm(-3)) and downtown site (sigma DDT 157 +/- 62pgm(-3)). The relationship between the isomers suggested that at the downtown site, the contribution of this pesticide to the environment was recent, probably for the control of diseases vectors. The congener pattern of PBDEs was dominated by BDE-47, and BDE-99 at all sites, with the downtown site having the highest concentrations of compound esters (sigma PBDEs 118 +/- 38pgm(-3)). Finally, high concentrations of PCBs were found at the industrial site (sigma PCBs 1677 +/- 134pgm(-3)), and the predominating homologs were 5-Cl and 6-Cl, in contrast to the other sites where PCBs were dominated by 3-Cl and 4-Cl. This is the first study of POPs carried out in the province of Cordoba.

Thermal release of guest molecules from poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) films, exhibiting host-guest cocrystalline (CC) phases with orientation of their chain axes being preferentially parallel or perpendicular to the film plane (c(parallel to) and c(perpendicular to) orientations), is studied. TGA analyses show that, for all the considered CC PPO films, temperatures of guest release for CC films with c(parallel to) orientation are definitely higher than those for CC films with c(perpendicular to) orientation, with differences even higher than 100 degrees C. Correspondingly, DSC scans of CC films with c(perpendicular to) orientation show separated endothermic peaks of guest release and melting, while CC films with c(parallel to) orientation only exhibit one broad endothermic peak with superimposed guest release, glass transition (T-g), and melting (T-m) phenomena. This control of temperatures of guest release could be helpful to maximize the thermal stability of host-guest PPO co-crystalline phases and to tailor temperatures of active guest release.

Fe3O4 nanoparticles (NPs) with a face-centered cubic (fcc) structure and two different morphologies (nanospheres and nanoprisms) were synthesized by a facile one-step method. The synthesized Fe3O4 nanospheres and nanoprisms were monocrystalline and separable in a magnetic field. In different volume ratios of oleylamine (OAm) to dibenzyl ether, the sizes of the prepared Fe3O4 NPs ranged from 5 to 21 nm. The OAm amount in the synthesis can significantly control the morphology of Fe3O4 NPs. As the OAm content increased from 10 ml to 30 ml, the faceted nanoprisms shrank while the nanospheres enlarged. At an OAm content of 25 ml, the nanoprisms diminished while more hexagonal and sphere-like particles appeared, implying a critical point of morphology transition from triangle to hexagon. The magnetic properties also depended on the NP morphology and size. The prepared Fe3O4 NPs are promising candidates in medical applications such as magnetic resonance imaging, targeted drug delivery, blood purification, and tumor hyperthermia.

The analysis of dust collected on the filters installed in the heating, ventilation, and air-conditioning (HVAC) systems, filter forensics, is a useful approach to explore concentration, size distribution, and composition of indoor particles. The extraction of dust from filters represents one of the biggest challenges to obtain accurate results from filter forensics. Although vacuuming is one of the most common dust extraction techniques, it is unclear how efficient it is and whether it provides a representative sample in terms of particle size. In this article, we used a high-capacity vacuum sampler to extract dust from 20 filters artificially loaded with well-characterized test dust as well as from 41 filters naturally loaded in residential HVAC systems. After all extractions, we recovered 0.1-5.5 g and 0.02-11.4 g of dust from the artificially and naturally loaded filters, respectively. These ranges were equivalent to 11.3-52.2% and 1.8-72.9% recovery efficiency, the ratio of dust recovered to the dust loaded in the filters. Multiple extractions were found to be an effective strategy to add to the recovery to enable filter forensics for the detection of multiple analytes. The recovered samples were slightly over-representative of particles greater than 10 mu m. Therefore, caution should be taken when applying filter forensics for studying contaminants associated with smaller particles. Copyright (c) 2020 American Association for Aerosol Research

A highly efficient PIFA-mediated Hofmann reaction of o-(pyridin-2-yl)aryl amides has been developed to selectively and rapidly construct various potential photocatalytically active 6H-pyrido[1,2-c]quinazolin-6-one derivatives. The use of a nontoxic and eco-friendly organoiodine reagent, operational simplicity, short reaction time, mild reaction conditions, broad substrate scope, high functional group tolerance, and excellent yields make this protocol very simple, practical, and easy to handle. It provides a feasible platform for developing novel organic fluorophore structures. Preliminary research for this purpose shows that the N-5-methylated pyridoquinazolinone 3a could be used as a photocatalyst in several organic transformations, indicating that it is a very promising lead fluorophore for developing new superior photocatalysts.

A highly active difunctional Ni-Mg2Si/gamma-Al2O3 was prepared by thermally decomposing nickel tetracarbonyl onto gamma-Al2O3 impregnated with Mg2Si. The non-catalytic hydroconversion (NCHC) and catalytic hydroconversion (CHC) of the extract (E) and extraction residue (ER) from Yinggemajianfeng lignite were investigated over Ni-Mg2Si/gamma-Al2O3 at 240 degrees C in n-hexane. Benzyloxybenzene and oxybis(methylene)dibenzene were used as lignite-related model compounds to speculate the possible mechanisms for the catalytic hydrocracking and hydrogenation over Ni-Mg2Si/gamma-Al2O3. As a result, more organic matter in ER was converted to soluble portion (SP) by the CHC than by the NCHC. The main SP from the CHC are chain alkanes and cyclanes, while that from the NCHC is rich in arenes and oxygen-containing organic compounds. The results indicate that Ni-Mg2Si/gamma-Al2O3 effectively catalyze the hydrocracking of > C-alk-O-linkages and the hydrogenation of aromatic rings in E and ER.

Hydrothermal treatment of gadolinium nitrate and 2,6-naphthalenedicarboxylic acid (H2NDC) afforded a new metal-organic framework compound, {[Gd-4(NDC)(6)(H2O)(6)]center dot 2H(2)O}n(1). Compound 1 has been characterized by single-crystal X-ray crystallography, elemental analysis, FT-IR spectroscopy, therrmogravimetric analysis (TGA) and powder X-ray diffraction analysis. It is crystallized in the monoclinic system with the P2(1)/n space group. Four crystallographically distinct Gd (III) centres are interconnected with each other through bridged carboxylato oxygen atoms and water molecules to form tetranuclear secondary building units, which are further connected through the carboxylato ligand and the network propagates along the crystallographic ac plane to form a 2D structure. Subsequent reinforcement from the remaining carboxylato oxygen atoms gives rise to a robust 3D framework structure. Thermogravimetric analysis demonstrates that compound 1 is fairly stable after dehydration under a nitrogen atmosphere. Notably, compound 1 is capable of catalyzing the O-arylation reaction efficiently between substituted phenols and bromoarene under heterogeneous conditions at 80 degrees C to afford unsymmetrical diarylethers.

The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

To investigate the status of organophosphate flame retardants (OPFRs) in indoor dust in China, published scientific studies were systematically collected and analyzed. The analysis revealed large variations among microenvironments, including offices (median: 14.59 mu g/g) and e-waste workshops (median: 13.36 mu g/g), with high levels of OPFRs contamination. Chlorinated organophosphate ester flame retardants (CI-OPFRs) were the dominant OPFRs (52-75%) in most indoor dust samples; however, in ewaste workshops, aryl- and alkyl-OPFRs were the most abundant. As an alternative flame retardant to polybrominated diphenyl ethers (PBDEs), OPFRs concentrations have increased in recent years in indoor environments in China. Urban sources are of greatest concern: Shanghai (mean: 13.54 mu g/g), Guangzhou (mean: 10.76 mu g/g), and Beijing (mean: 9.37 mu g/g) have high EOPFRs contamination levels in indoor dust. Compared to other countries, the OPFRs concentrations in indoor dust in all studied microenvironments from China (median: 8.81 mu g/g) were low. The estimated daily intakes of EOPFRs by dust ingestion for adults and children were 2.12 and 11.06 ng/kg/body weight/day (average), respectively. Human exposure to OPFRs through the accidental intake of indoor dust does not pose a direct health risk to the Chinese population. However, indoor dust ingestion is an important route for human exposure to OPFRs. (C) 2020 Elsevier Ltd. All rights reserved.
