Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1116-77-4, Name is 4,4-Diethoxy-N,N-dimethyl-1-butanamine, molecular formula is C10H23NO2, belongs to ethers-buliding-blocks compound, is a common compound. In a patnet, author is Liu, Jing, once mentioned the new application about 1116-77-4, Category: ethers-buliding-blocks.

The production and usage of polybrominated diphenyl ethers (PBDEs) has been gradually phased out and the application of alternative halogenated flame retardants (AHFRs) has been continuously increased. It is essential to understand how the evolving flame retardants industry has affected the occurrence and flux of legacy and alternative flame retardants so that better pollution control measures can be made accordingly. Air, rainwater, inflowing river water, pond water, pond sediment, fish feed, and fish collected from freshwater cultured fish ponds (FWCFPs) within the Pearl River Delta, South China were analyzed for PBDEs and AHFRs. Concentrations of AHFRs in air (range; median: 7.8-870; 210 pg m(-3)), rainwater (0.88-65; 4.8 ng L-1), and sediment (19-120; 54 ng g(-1) dry weight (d.w.)) were one order of magnitude higher than those of PBDEs in air (12-98; 21 pg m(-3)), rainwater (0.18-15; 0.70 ng L-1), and sediment (1.5-9.6, 2.9 ng g(-1) d.w.) (t-test; p < 0.05). Decabromodiphenyl ether and decabromodiphenylethane were the predominant BDE and AHFR components, respectively, agreeing well with the production and usage patterns of flame retardants in China. The average input fluxes of AHFRs to the FWCFPs via dry deposition, wet deposition, net air-water exchange, and feeding (38.6, 20.6, and 2.14, mu g m(-2) yr(-1)) were one order of magnitude higher than those of PBDEs (3.44, 5.17, and -10.1, mu g m(-2) yr(-1)). Elevated occurrence and input fluxes of AHFRs suggested that aquaculture production is potentially facing a new challenge from alternative flame retardants. Atmospheric dry and wet deposition are important input sources of AHFRs to the FWCFPs. Feeding is an important input pathway for both PBDEs and AHFRs. Pollution control measures should be modified to accommodate the evolving flame retardants industry. (C) 2020 Elsevier B.V. All rights reserved.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 150-78-7, Name is 1,4-Dimethoxybenzene, molecular formula is C8H10O2, belongs to ethers-buliding-blocks compound. In a document, author is Thakur, D. A., introduce the new discover, Quality Control of 1,4-Dimethoxybenzene.

Low level radioactive liquid waste (LLW) is generated at different stages of operation of reprocessing as well as radioactive waste management. The LLW generated here is alkaline with high salt content. It contains different radioisotopes namely(106)Ru, Sb-125, Tc-99, Cs-137, Sr-90 and traces of Pu. Presence of Tc-99 in LLW is of great environmental concern due to its long half-life (T-1/2: 2 x 10(5) years) and mobility. Hence it needs to be separated from LLW to maximum possible extent prior to discharge to environment. In this paper, study carried out for separation of Tc-99 using the crown ether, Di-tert-Butyldibenzo-18-Crown-6 (DtBuDB18C6). The performance of the composite material was evaluated with respect to Tc-99 uptake and the effect of various parameters like pH, salt concentration, time period and temperature on K-d value was studied.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 150-78-7, Name is 1,4-Dimethoxybenzene, SMILES is COC1=CC=C(OC)C=C1, in an article , author is Wu, Jie, once mentioned of 150-78-7, HPLC of Formula: C8H10O2.

Alternative crosslinking polyurethanes (ACPUs) were created by reacting a commercial allophanate-modified polyisocyanate with propargyl alcohol to yield a poly(alkynyl carbamate); a polyazide co-reactant was created from an acrylic polyol. Conversion of the polyisocyanate into the corresponding poly(propargyl carbamate) resulted in a dramatic viscosity increase. Poly(alkynyl carbamate) prepolymers with lower viscosities were designed by replacing various fractions of the propargyl alcohol with commercial glycol ether plasticizers, ethylene glycol monoethyl ether (EGMEE), diethylene glycol monomethyl ether (DEGMEE), and diethyleneglycol monobutyl ether (DEGBE). Triethylene glycol monopropargyl ether was also studied to provide plasticization with no sacrifice of alkyne functionality. For each commercial glycol ether plasticizer, viscosity was unaffected or increased at a loading level of 10 mol%. At 25 mol%, average viscosity reduction was 36 %, with DEGBE yielding the greatest reduction at 55 %. At 33 mol%, no further decreases were observed. Triethylene glycol monopropargyl ether yielded a 76 % reduction in viscosity at 33 mol%; 100 mol% substitution yielded no further reduction. Coatings produced from the modified poly(alkynyl carbamate)s were softer and displayed lower glass transition temperatures compared to a polyisocyanate/polyol control and a 100 % propargylated poly(alkynyl carbamate)/polyazide control. Solvent resistance of the modified coatings was the same as the controls except for those created from DEGBE and from DEGMEE at 33 mol%.

Hypothesis: The insertion of polyether spacers between the anionic head and the alkyl chain of ionic surfactants significantly improves their salt-tolerance. The aim of this work is to study whether the petro-based polyethoxy spacer can be replaced by a glyceryl ether group for high salinity applications. Experiments: A series of amphiphilic sodium salts of alkyl glyceryl ether carboxylates are synthesized with different alkyl chain lengths from 4 to 12 and various spacers between the glyceryl and the carboxylate groups. Their aggregation behavior is studied by tensiometry and their amphiphilicities are assessed by the PIT-slope method. The dramatic effect of the methylation of the glyceryl spacer on the salt-tolerance is highlighted, and rationalized by DFT calculations and molecular dynamics. Findings: In contrast to the corresponding sodium soap, n-C6H13-CO2Na, and to the non-methylated counterpart, the sodium salt of 1-pentyl-3-methyl glyceryl ether methylene carboxylate ([5.0.1]-CH2CO2Na) exhibits an excellent salt-tolerance since it remains water-soluble with NaCl or CaCl2 concentrations greater than 20 wt% at 25 degrees C.

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, 93-04-9, Name is 2-Methoxynaphthalene, SMILES is COC1=CC2=C(C=CC=C2)C=C1, belongs to ethers-buliding-blocks compound. In a document, author is Eduardo Arteaga, Jose, introduce the new discover, Formula: C11H10O.

Objectives To determine furfural biotransformation capabilities of Acinetobacter baylyi ADP1 and Acinetobacter schindleri ACE. Results Acinetobacter baylyi ADP1 and A. schindleri ACE could not use furfural as sole carbon source but when acetate was used as substrate, ADP1 and ACE biotransformed 1 g furfural/l in 5 and 9 h, respectively. In both cases, the product of this biotransformation was difurfuryl-ether as shown by FT-IR and H-1 and C-13 NMR spectroscopy. The presence of furfural decreased the specific growth rate in acetate by 27% in ADP1 and 53% in ACE. For both strains, the MIC of furfural was 1.25 g/l. Nonetheless, ADP1 biotransformed 2 g furfural/l at a rate of 1 g/l/h in the stationary phase of growth. A transcriptional analysis of possible dehydrogenases involved in this biotransformation, identified that the areB and frmA genes were highly overexpressed after the exposure of ADP1 to furfural. The products of these genes are a benzyl-alcohol dehydrogenase and an alcohol dehydrogenase. Conclusions Acinetobacter baylyi ADP1 is a candidate for the biological detoxification of furfural, a fermentation inhibitor present in lignocellulosic hydrolysates, with the possible direct involvement of the AreB and FrmA enzymes in the process.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 93-04-9 is helpful to your research. Formula: C11H10O.

In an article, author is Sarkar, Debarshi, once mentioned the application of 150-78-7, HPLC of Formula: https://www.ambeed.com/products/150-78-7.html, Name is 1,4-Dimethoxybenzene, molecular formula is C8H10O2, molecular weight is 138.16, MDL number is MFCD00008401, category is ethers-buliding-blocks. Now introduce a scientific discovery about this category.

Decabromodiphenyl ether (BDE-209) is widely used as a flame retardant in many products like electronic equipments, plastics, furniture and textiles. BDE-209, a thyroid hormones (THs)-disrupting chemical, affects male reproductive health through altered THs status in mouse model. The present study was designed in continuation to our earlier work to elucidate whether early life exposure to BDE-209 has a long term potential risk to male reproductive health. This study, therefore, aimed to evaluate the effect of maternal BDE-209 exposure during lactation and to elucidate possible mechanism(s) of its action on male reproduction in adult Parkes mice offspring. Lactating female Parkes mice were orally gavaged with 500, and 700 mg/kg body weight of BDE-209 in corn oil from postnatal day (PND) 1 to PND 28 along with 6-propyl-2-thiouracil (PTU)-treated positive controls and vehicle-treated controls. Male pups of lactating dams were euthanized at PND 75. Maternal BDE-209 exposure during lactation markedly affected histoarchitecture of testis and testosterone production with concomitant down-regulation in the expression of various steroidogenic markers in adult offspring. Maternal exposure to BDE-209 during lactation also interfered with germ cell dynamics and oxidative status in testes of adult mice offspring. A decreased expression of connexin 43 and androgen receptor was also evident in testes of these mice offspring; further, number, motility and viability of spermatozoa were also adversely affected in these mice. The results thus provide evidences that maternal exposure to BDE-209 during lactation causes reproductive toxicity in adult mice offspring.

The combination of materials with different magnetic properties at the nanoscale can lead to phenomena such as exchange bias via coupling effects, which shows huge potential for applications, e.g., in storage media or magnetic sensors. Whilst such structures so far are obtained via complex processes of alternating deposition from the gas phase hampering their application, their preparation from nanoparticle dispersions would not only be simplified but also enable a broad variety of possible material combinations and structures. Thereby, the processing of hard magnetic nanoparticles is challenging but can be circumvented by the use of precursor materials with subsequent phase transformation.

In this work, Al grafted SBA-16 (Al-SBA-16) is converted into a fully crystalline hierarchical mesoporous ZSM-5 zeolite with hydrothermal stability by steam assisted crystallization under controlled conditions. The secondary mesoporosity is due to reorganization and recrystallization events happening upon steaming the precursor. Two mesoporous aluminosilicates (Al-SBA-16s) are used as the precursors of zeolites. The precursors are obtained by post-synthetic Al grafting on the silica walls of SBA-16 with aluminium isopropoxide and sodium aluminate. Mesoporous ZSM-5 zeolites obtained from the Al-SBA-16 precursors and commercial ZSM-5 are characterized using XRD, XRF, FT-IR, TEM, N-2 adsorption, Al-27 and Si-29 MAS NMR, and TPD of NH3. The results indicated the presence of intraparticle mesoporosity in the prepared mesoporous zeolites and they have comparable crystallinity with commercial ZSM-5. Catalytic activity of the synthesized mesoporous zeolites in benzylation of mesitylene is found to be comparatively more than commercial ZSM-5, which shows existence of micro/meso hierarchical structure in the mesoporous ZSM-5 zeolites. The aluminium sources, aluminium isopropoxide and sodium aluminate have a remarkable influence on the textural, acidity, and hydrothermal stability characteristics of the synthesized mesoporous ZSM-5 zeolites.
