Removal of organic pollutants from super heavy oil wastewater by lignite activated coke was written by Tong, Kun;Zhang, Yihe;Fu, Dan;Meng, Xianghai;An, Qi;Chu, Paul K.. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2014.Application In Synthesis of 1-Chlorooctadecane This article mentions the following:

Extraction of organic pollutants from super heavy oil wastewater (SHOW) by lignite activated coke (LAC) is investigated. The factors studied include the exposure time, temperature, and different pollutant concentrations in the wastewater. The equilibrium adsorption data are analyzed by the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherms. The best match is obtained by the Freundlich isotherm and a chem. mechanism is suggested based on the D-R model. The adsorption kinetics follows the pseudo second order model and the mass transfer model suggests that external and intra-particle diffusion influences the adsorption process. Thermodn. studies show that adsorption of organic materials is spontaneous at high temperature (303 and 313 K) but not so at lower temperature (293 K) and reveals an endothermic process and increase in randomness during adsorption. The pilot dynamic adsorption test indicates that LAC can remove not only organic pollutants such as COD, NH₃-N, oils, but also inorganic pollutants such as Mg²⁺, Ca²⁺, and salts. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Application In Synthesis of 1-Chlorooctadecane).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application In Synthesis of 1-Chlorooctadecane

And the article was included in Journal of the Chemical Society [Section] A: Inorganic, Physical, Theoretical in 1968.Synthetic Route of C10H10Cl2Pt This article mentions the following:

Bridge-splitting reactions of complexes of the type [M(diene.OMe)X]2 (M = Pd(II), Pt(II); diene = cycloocta-1,5-diene, dicyclopentadiene; X = Cl, Br) by neutral ligands (L) having N or P as donor atoms are reported. For the products [M(diene.OMe)LX] two structures are possible, i.e., with L cis to the olefinic double bond (A) or trans to it (B). On the basis of far-ir, spectra, structure (A) has been attributed to [Pd(diene.OMe)(py)Cl] and [Pt(diene.-OMe)LX)] (L = pyridine and p-toluidine). Structure (B) has been attributed to [Pt(diene.OMe)(PPh3)X] and to the analogous Pd(II) complexes. From [M(diene.OMe)(py)Cl] the pyridine is displaced by another neutral ligand, whereas the chloride ion is displaced only by an anionic one. The far-ir spectra (500-60 cm.-1) of the dimers [M(diene.OMe)X]2 are reported and the metal-bridging halogen stretching frequencies are assigned on the basis of a Cipoint-group symmetry. The v(M-Clbridging) falls in the range 298-216 cm.-1, v(M-Brbridging 201-148 cm.-1, and v(M-Ibridging) 165-122 cm.-1 In the experiment, the researchers used many compounds, for example, Dichlorodi(cyclopenta-1,3-dien-1-yl)platinate(II) (cas: 12083-92-0Synthetic Route of C10H10Cl2Pt).

Synthesis of Furans and Pyrroles from 2-Alkoxy-2,3-dihydrofurans Through a Nucleophilic Substitution-Triggered Heteroaromatization was written by Liu, Changhui;Zhou, Li;Huang, Wenbo;Wang, Man;Gu, Yanlong. And the article was included in Advanced Synthesis & Catalysis in 2016.Reference of 96568-04-6 This article mentions the following:

An effective method to synthesize α-functionalized furan and pyrrole derivatives was developed using 2-alkoxy-2,3-dihydrofurans as modular precursors. This protocol featured a previously unreported tandem nucleophilic substitution/heteroaromatization reaction. Nucleophiles such as indole, α-oxoketene dithioacetal, trimethoxybenzene, and dimethoxynaphthalene can react readily with 2-alkoxy-2,3-dihydrofurans to afford α-functionalized five-membered ring heterocycles in the presence of acid catalysts, such as copper bromide and iron chloride. The mechanism of the reaction was also discussed, in which the first step, nucleophilic substitution, is the key in triggering the succeeding heteroaromatization. This method can also be extended to the synthesis of dihydrothiophenes.

CON4EI: Selection of the reference chemicals for hazard identification and labelling of eye irritating chemicals was written by Adriaens, E.;Alepee, N.;Kandarova, H.;Drzewieckac, A.;Gruszka, K.;Guest, R.;Willoughby, J. A. Sr.;Verstraelen, S.;Van Rompay, A. R.. And the article was included in Toxicology In Vitro in 2017.SDS of cas: 96568-04-6 This article mentions the following:

Assessment of the acute eye irritation potential is part of the international regulatory requirements for testing of chems. In the past, several prospective and retrospective validation studies have taken place in the area of serious eye damage/eye irritation testing. Success in terms of complete replacement of the regulatory in vivo Draize rabbit eye test has not yet been achieved. A very important aspect to ensure development of successful alternative test methods and/or strategies for serious eye damage/eye irritation testing is the selection of appropriate reference chems. A set of 80 reference chems. was selected for the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project, in collaboration with Cosmetics Europe, from the Draize Reference Database published by Cosmetics Europe based on key criteria that were set in their paper (e.g. balanced by important driver of classification and phys. state). The most important goals of the CON4EI project were to identify the performance of eight in vitro alternative tests in terms of driver of classification and to identify similarities/differences between the methods in order the build a successful testing strategy that can discriminate between all UN GHS categories. This paper provides background on selection of the test chems. In the experiment, the researchers used many compounds, for example, Ethyl 3-(2,6-Dichloro-5-fluoro-3-pyridyl)-3-oxopropionate (cas: 96568-04-6SDS of cas: 96568-04-6).

Nonsolvent Application of Ionic Liquids: Organo-Catalysis by 1-Alkyl-3-methylimidazolium Cation Based Room-Temperature Ionic Liquids for Chemoselective N-tert-Butyloxycarbonylation of Amines and the Influence of the C-2 Hydrogen on Catalytic Efficiency was written by Sarkar, Anirban;Roy, Sudipta Raha;Parikh, Naisargee;Chakraborti, Asit K.. And the article was included in Journal of Organic Chemistry in 2011.Application of 18437-66-6 This article mentions the following:

Imidazolium ionic liquids such as [bmim]⁺·Tf₂N^– (I; bmim = 1-butyl-3-methylimidazolium) efficiently catalyze the chemoselective N-tert-butyloxycarbonylation of amines; the catalyst can be recycled by extraction of the product into ether followed by heating under vacuum. The ionic liquid catalyst activates di-tert-Bu dicarbonate electrophilically through formation of a bifurcated hydrogen bond with the C-2 hydrogen of the imidazolium cation; the role of the C2 proton in catalysis is supported by the change in the ¹H NMR shift of the imidazolium C-2 hydrogen of I from δ 8.39 to δ 8.66 in the presence of Boc₂O and by the significantly reduced activities of analogous 1-butyl-2,3-dimethylimidazolium ionic liquids lacking C-2 hydrogens. Alkylamines are tert-butoxycarbonylated more rapidly than aromatic amines, allowing the chemoselective protection of the benzylamine moiety of 4-aminobenzylamine; Boc protection of piperidine and 1-piperidineethanamine in the presence of I yields a 62:38 mixture of the Boc piperidine and tert-Bu piperidineethylcarbamate. The efficiencies of the Boc protection of 3-chloro-4-fluoroaniline in the presence of I and in the presence of Lewis acids (from literature references) are compared. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Application of 18437-66-6).
