Application In Synthesis of 1-Chloro-2-methylbenzene. Nguyen, OT; Ha, DD in [Oanh Thi Nguyen] Dong Thap Univ, Ctr Chem Anal, Cao Lanh, Dong Thap, Vietnam; [Duc Danh Ha] Dong Thap Univ, Fac Engn Technol, Cao Lanh, Dong Thap, Vietnam published Degradation of chlorotoluenes and chlorobenzenes by the dual-species biofilm of Comamonas testosteroni strain KT5 and Bacillus subtilis strain DKT in 2019.0, Cited 56.0. The Name is 1-Chloro-2-methylbenzene. Through research, I have a further understanding and discovery of 95-49-8.

The cooperation of Bacillus subtilis strain DKT and Comamonas testosteroni KT5 was investigated for biofilm development and toluenes and chlorobenzenes degradation. Bacillus subtilis strain DKT and C. testosteroni KT5 were co-cultured in liquid media with toluenes and chlorobenzenes to determine the degradation of these substrates and formation of dual-species biofilm used for the degradation process. Bacillus subtilis strain DKT utilized benzene, mono- and dichlorinated benzenes as carbon and energy sources. The catabolism of chlorobenzenes was via hydroxylation, in which chlorine atoms were replaced by hydroxyl groups to form catechol, followed by ring fission via the ortho-cleavage pathway. The investigation of the dual-species biofilm composed of B. subtilis DKT and C. testosteroni KT5 (a toluene and chlorotoluene-degrading isolate with low biofilm formation) showed that B. subtilis DKT synergistically promoted C. testosteroni KT5 to develop biofilm. The bacterial growth in dual-species biofilm overcame the inhibitory effects caused by monochlorobenzene and 2-chlorotoluene. Moreover, the dual-species biofilm showed effective degradability toward the mixture of these substrates. This study provides knowledge about the commensal relationships in a dual-culture biofilm for designing multispecies biofilms applied for the biodegradation of toxic organic substrates that cannot be metabolized by single-organism biofilms.

V2O5/TiO2-SiO2-MoO3 (TSM) catalysts exhibit enhanced redox capabilities, but the role of each species in the mixed oxide support is not well understood. Herein, the physicochemical characteristics of molybdenum oxide in TSM were investigated using X-ray diffraction, X-ray photoelectron spectroscopy, and X-ray absorption fine structure spectroscopy, and the performance of V/TSM catalysts for the oxidative decomposition of o-chlorotoluene was examined. The V/TSM catalysts exhibited superior performances in this decomposition reaction at low temperatures. The molybdenum species were highly dispersed as Mo6+, replacing Ti4+ in the anatase TiO2 framework and forming a solid solution. The redox capability of the vanadium species in the catalyst was enhanced by electron transfer from the TSM support to vanadium, likely due to the coexistence of Mo6+ and Ti(4+ )in the TSM solid solution, which has a unique structure. These results are expected to contribute to enhancing the abatement of dioxins at low temperatures.

Disposable sanitary pads are a necessity for women’s health, but safety concerns regarding the use of these products have created anxiety. The aim of this study was to conduct a risk assessment of 74 volatile organic compounds (VOCs), which were expected to be contained within sanitary pads. Of the 74 VOCs, 50 were found in sanitary pads retailed in Korea at concentrations ranging from 0.025 to 3548.09 mu g/pad. In order to undertake a risk assessment of the VOCs, the toxicological database of these compounds in the United States Environmental Protection Agency (USEPA), Agency for Toxic Substances and Disease Registry (ATSDR), National Toxicology Program (NTP) and World Health Organization (WHO) was searched. Ethanol was found to exhibit the highest reference dose (RfD) while 1,2-dibromo-3-chloro-propane displayed the lowest RfD. Consequently, a worst-case exposure scenario was applied in this study. It was assumed that there was the use of 7.5 sanitary napkins/day for 7 days/month. In the case of panty liners or overnight sanitary napkins, the utilization of 90 panty liners/month or 21 overnight sanitary napkins/month was assumed, respectively. In addition, 43 kg, the body weight of 12 to 13-year-old young women, and 100% VOCs skin absorption were employed for risk assessment. The systemic exposure dose (SED) values were calculated ranging from 1.74 (1,1,2-trichloroethane) ng/kg/day to 144.4 (ethanol, absolute) mu g/kg/day. Uncertainty factors (UFs) were applied ranging from 10 to 100,000 in accordance with the robustness of animal or human experiments. The margin of exposure (MOE) of 34 VOCs was more than 1 (acceptable MOE > 1). Applicable carcinogenic references reported that the cancer risk of five VOCs was below 10(-6). Based on our findings, evidence indicates that the non-cancer and cancer risks associated with VOCs detected in sanitary pads currently used in South Korea do not pose an adverse health risk in women.

I found the field of Chemistry very interesting. Saw the article Preparation of sub-microspherical Fe3O4@PDA-Pd NPs catalyst and application in catalytic hydroreduction reaction of halogenated aromatic nitro compounds to prepare halogenated aromatic amines published in 2019. Product Details of 87-63-8, Reprint Addresses Xia, AB (corresponding author), Zhejiang Univ Technol, Catalyt Hydrogenat Res Ctr, Zhejiang Key Lab Green Pesticides & Cleaner Prod, Hangzhou 310014, Zhejiang, Peoples R China.. The CAS is 87-63-8. Through research, I have a further understanding and discovery of 2-Chloro-6-methylaniline

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.

We report herein P(III)-directed C-H bond alkenylation of (dialkyl)- and (diaryl)biarylphosphines using internal alkynes. Chloride-free [Rh(OAc)(COD)](2) acts as a better catalyst than commercially available [RhCl(COD)](2). Conditions were developed to control the mono- and difunctionalization depending on the alkyne stoichiometry. One of these novel bisalkenylated (dialkyl)biarylphosphines was employed for the preparation of a palladium(II) complex, and some of these functionalized ligands outperformed their corresponding unfunctionalized phosphines in Pd-catalyzed amidation with sterically hindered aryl chlorides.

Here, we report a class of ligands based on oxalohydrazide cores and N-amino pyrrole and N-amino indole units that generates long-lived copper catalysts for couplings that form the C-O bonds in biaryl ethers. These Cu-catalyzed coupling of phenols with aryl bromides occurred with turnovers up to 8000, a value which is nearly two orders of magnitude higher than those of prior couplings to form biaryl ethers and nearly an order of magnitude higher than those of any prior copper-catalyzed coupling of aryl bromides and chlorides. This ligand also led to copper systems that catalyze the coupling of aryl chlorides with phenols and the coupling of aryl bromides and iodides with primary benzylic and aliphatic alcohols. A wide variety of functional groups including nitriles, halides, ethers, ketones, amines, esters, amides, vinylarenes, alcohols and boronic acid esters were tolerated, and reactions occurred with aryl bromides in pharmaceutically related structures.
