Chloroaluminate ionic liquid bound on magnetic nanoparticles (Fe3O4@O2Si[PrMIM]Cl·AlCl3) was prepared and used as a heterogenous Lewis acidic catalyst for the Friedel-Crafts sulfonylation of aromatic compounds with sulfonyl chlorides or p-toluenesulfonic anhydride. The catalyst′s stability, efficiency, easy recovery, and high recyclability without considerable loss of catalytic capability after four recycles were evidence of its advantages. Furthermore, the stoichiometry, wide substrate scope, short reaction time, high yield of sulfones, and solvent-free reaction condition also made this procedure practical, ecofriendly, and economical. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Synthetic Route of 150-78-7

On July 21, 2020, Zheng, Wenxiao; Zhu, Liuyi; Liang, Sheng; Ye, Jinshao; Yang, Xin; Lei, Zhenchao; Yan, Zhang; Li, Yongdong; Wei, Chaohai; Feng, Chunhua published an article.Formula: C8H10O2 The title of the article was Discovering the Importance of ClO• in a Coupled Electrochemical System for the Simultaneous Removal of Carbon and Nitrogen from Secondary Coking Wastewater Effluent. And the article contained the following:

inorganic pollutants in actual wastewater, e.g., halides and CO32-/HCO3-, may have neg. effects on electrochem. system performance due to their capability of quenching HO-. however, the authors determined the presence of Cl- and HCO3- in an electrochem. system was conducive to ClO- formation, which played an important role in promoting simultaneous removal of bio-refractory organics and N from secondary coking wastewater effluent. a 6-h operation of the coupled electrochem. system (undivided electrolytic cell with PbO2/Ti anode and Cu/Zn cathode) at a 37.5 mA/cm2 c.d. removed 87.8% of COD and 86.5% total N. ESR results suggested ClO- formation in the system and probe experiments confirmed the ClO- predominance, whose steady-state concentrations (8.08 x 10-13 M) were 16.4, 26.5, and 1609.5 times those of Cl2- (4.92 x 10-14 M), OH- (3.05 x 10-14 M), and Cl- (5.02 x 10-16 M), resp. the COD removal rate constant and the Faradaic efficiency of anodic oxidation obtained with Cl- and HCO3- was linearly proportional to the natural logarithm of the ClO- concentration; specific energy consumption was inversely correlated to it, demonstrating the crucial role of ClO- for pollutant removal. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On January 31, 2022, Kiliclar, Huseyin Cem; Gencosman, Emirhan; Yagci, Yusuf published an article.Formula: C8H10O2 The title of the article was Visible light induced conventional step-growth and chain-growth condensation polymerizations by electrophilic aromatic substitution. And the article contained the following:

A novel visible light induced step-growth polymerization by electrophilic aromatic substitution between photochem. generated carbocations and dimethoxybenzene nucleophile is described. Conventional step-growth polymerization and chain-growth condensation polymerization (CCP) mechanisms are presented. It is found that by changing the molar ratios of the monomers slightly, the CCP mechanism becomes operative and relatively higher mol. weight polymers are obtained because of the higher reactivity of the end groups of the intermediates and oligomers than that of the monomers. The possibility of grafting onto polymers containing epoxide at their side chains by photoinduced chain end activation of poly(dimethoxyphenylene methylene) is demonstrated. This study is expected to promote potential applications of the combination of photoinduced electron transfer reactions and CCP in macromol. synthesis and material science. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

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%.

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.

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.
