CAS

  • or
1,1,2,2-Tetrach loroethane, with the chemical formula C2H2Cl4, is a clear, heavy, non-flammable liquid chemical compound characterized by a sweet odor. It is derived from hydrocarbons, specifically consisting of two carbon atoms and four chlorine atoms. 1,1,2,2-Tetrach loroethane is often used in the industrial sector and is known for its higher density than water, causing it to sink when in contact with water. However, it is important to note that 1,1,2,2-Tetrach loroethane is considered toxic and can pose potential health risks, including harm to the liver, kidney, and lungs upon inhalation, ingestion, or skin contact.

Check Digit Verification of cas no

The CAS Registry Mumber 79-34-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79-34:
(4*7)+(3*9)+(2*3)+(1*4)=65
65 % 10 = 5
So 79-34-5 is a valid CAS Registry Number.

PROCESS FOR THE PRODUCTION OF CHLORINATED METHANES

-

Paragraph 0062; 0063, (2017/04/11)

The present invention provides processes for the production of chlorinated methanes via the direct chlorination of methane. The processes include a dehydrochlorination and/or chlorination step that converts up to 100% of the higher chlorinated alkanes in a process stream from the methane chlorination reaction into more highly chlorinated alkanes. These more highly chlorinated alkanes can be easily removed from the process stream. The use of a cost effective feedstream of crude methane is thus rendered possible, without additional capital expenditure for the sophisticated separation equipment required to separate ethane and other hydrocarbon components from the methane feed.

Determination of the rate constant of the reaction of CCl2 with HCl

Gomez, Nicolas D.,D'Accurso, Violeta,Manzano, Francisco A.,Codnia, Jorge,Azcarate, M. Laura

, p. 382 - 388 (2014/05/20)

The rate constant of the reaction between CCl2 radicals and HCl was experimentally determined. The CCl2 radicals were obtained by infrared multiphoton dissociation of CDCl3. The time dependence of the CCl2 radic

ArF laser photolytic deposition and thermal modification of an ultrafine chlorohydrocarbon

Pola, Josef,Galikova, Anna,Subrt, Jan,Ouchi, Akihiko

experimental part, p. 625 - 629 (2011/10/19)

MW ArF laser irradiation of gaseous cis-dichloroethene results in fast decomposition of this compound and in deposition of solid ultrafine Cl- and H-containing carbonaceous powder which is of interest due to its sub-microscopic structure and possible reactive modification of the C-Cl bonds. The product was characterized by electron microscopy, and FTIR and Raman spectra and it was revealed that HCl, H2, and C/H fragments are lost and graphitic features are adopted upon heating to 700°C.

Photocatalysis of chloroform decomposition by hexachloroosmate(IV)

Pena, Laura A.,Hoggard, Patrick E.

body text, p. 467 - 470 (2010/10/19)

Hexachloroosmate(IV) effectively catalyzes the photodecomposition of chloroform in aerated solutions. The decomposition products are consistent with a mechanism in which excited state OsCl62- reduces chloroform, rather than one involving photodissociation of chlorine atoms. Trace amounts of ethanol or water in the chloroform lead to photosubstitution to form OsCl5(EtOH)- or OsCl5(H2O) -, neither of which is photocatalytically active.

Photocatalytic degradation of lindane by polyoxometalates: Intermediates and mechanistic aspects

Antonaraki,Triantis,Papaconstantinou,Hiskia

experimental part, p. 119 - 124 (2010/08/22)

The photocatalytic degradation of lindane (γ-1,2,3,4,5,6-hexachlorocyclohexane) has been studied in the presence of the polyoxometalate PW12O403- in aqueous solutions. Lindane is fully decomposed to CO2, Cl- and H2O, while a great variety of intermediates has been detected using GC-MS, including aromatic compounds (dichlorophenol, trichlorophenols, tetrachlorophenol, hexachlorobenzene, di- and trichloro-benzenodiol), non-aromatic cyclic compounds (penta-, tetrachlorocyclohexene, heptachlorocyclohexane), aliphatic compounds (tetrachloroethane) and condensation products (polychlorinated biphenyls). The number and nature of the intermediates implies that the mechanism of decomposition of lindane is based on both oxidative and reductive processes. Common intermediates have been reported during photolysis of lindane in the presence of titanium dioxide. A similar overall mechanism of polyoxometalates and TiO2 photocatalysis through the formation of common reactive species is suggested.

Fluorodecarboxylation, rearrangement and cyclisation: the influence of structure and environment on the reactions of carboxylic acids with xenon difluoride

Ramsden, Christopher A.,Shaw, Maxine M.

experimental part, p. 3321 - 3324 (2009/08/09)

The reactions of structurally diverse carboxylic acids with XeF2 in both CH2Cl2/Pyrex and CH2Cl2/PTFE have been studied. Pyrex appears to be a very effective heterogeneous catalyst for an electrophilic mode of reaction of polarised XeF2, leading to rearrangement, cyclisation and cationic products. In CH2Cl2/PTFE, fluorodecarboxylation is the main mode of reaction, in accordance with previous studies, and may occur via a SET reaction of unpolarised XeF2.

Polychloroethyltrifluoromethylsulfonamides from N,N-dichlorotrifluoromethylsulfonamide and dichloroethenes

Kondrashov, Evgenii V.,Rozentsveig, Igor B.,Levkovskaya, Galina G.,Mirskova, Anna N.

, p. 25 - 26 (2007/10/03)

The interaction of trifluoromethylsulfonic acid N,N-dichloroamide with 1,1- and 1,2-dichloroethenes is a convenient way to N-(2,2,2-trichloroethyl)trifluoromethylsulfonamide, N-(2,2-dichloroethylidene)amide of trifluoromethylsulfonic acid and its derivatives.

Generation of radical species in surface reactions of chlorohydrocarbons and chlorocarbons with fluorinated gallium(III) oxide or indium(III) oxide

Thomson

, p. 1881 - 1885 (2007/10/03)

The reactions of C1 and C2 chlorohydrocarbons and chlorocarbons have been studied with the Lewis acid catalysts fluorinated gallium(III) oxide and fluorinated indium(III) oxide, respectively. Product analysis shows chlorine-for-fluorine exchange reactions together with the formation of 2-methylpropane and its chlorinated analogues 2-chloromethyl-1,3-dichloropropane and 2-chloromethyl-1,2,3-trichloropropane. Reactivities of the chlorohydrocarbon probe molecules show fluorinated gallium(III) oxide to be a stronger Lewis acid than fluorinated indium(III) oxide. The formation of the symmetrical butyl compounds is consistent with the generation of surface radical species and is also consistent with a 1,2-migration mechanism operating within radical moieties at the Lewis acid surface.

Role of copper species in chlorination and condensation reactions of acetylene

Wehrmeier, Andreas,Lenoir, Dieter,Sidhu, Sukh S.,Taylor, Philip H.,Rubey, Wayne A.,Kettrup, Antonious,Dellinger, Barry

, p. 2741 - 2748 (2007/10/03)

We examined the thermally induced acetylene chlorination and condensation reactions on different types of copper salt impregnated surfaces. The System for Thermal Diagnostic Studies provided a powerful tool to study these reactions under defined reaction conditions, which were related to typical conditions in postcombustion incineration processes. Experiments were conducted with acetylene or acetylene/HCl mixtures in a quarts reactor filled with a borosilicate foam of known pore size at temperatures between 150 and 500 °C. Borosilicate was also used as the catalytic support for gas-solid reactions of acetylene and acetylene/HCl mixtures with CuCl2 and CuO. Reaction products were trapped in-line and analyzed by GC/MS. It was shown that borosilicate is not able to catalyze acetylene condensation reactions. CuCl2-impregnated borosilicate was a highly effective catalyst for acetylene chlorination/condensation reactions at temperatures above 150 °C. The same behavior was found for CuO- impregnated borosilicate in the presence of HCl. However, temperatures above 300 °C were required for this catalytic system. Mainly perchlorinated C-2 to C-8 hydrocarbons were trapped as reaction products in the gas phase. Maximum yields for acetylene chlorination/condensation reactions in each related catalytic system were found at temperatures between 300 and 400 °C. Results of the surface-catalyzed acetylene chlorination and condensation reactions were summarized in a global mechanism. A ligand transfer oxidative chlorination of acetylene with CuCl2 was proposed to be the initiation of acetylene with CuCl2 was proposed to be the initiating step. Chlorinated acetylene then condenses to higher molecular weight compounds, catalyzed by CuCl in metallacyclization reactions.
