7803-68-1 Usage

General Description

Orthotelluric acid, also known as telluric acid, is a chemical compound with the formula H6TeO6. It is a colorless and odorless crystalline solid that is highly soluble in water. Orthotelluric acid is an oxidizing agent and is primarily used in analytical chemistry and as a reagent for the detection of certain metals. It is also used in the production of pigments for ceramics and glass. When heated, orthotelluric acid decomposes to form tellurium dioxide, water, and oxygen. Despite its limited commercial applications, the compound is of interest to researchers due to its unique chemical properties and potential uses in various industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 7803-68-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,8,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7803-68:
(6*7)+(5*8)+(4*0)+(3*3)+(2*6)+(1*8)=111
111 % 10 = 1
So 7803-68-1 is a valid CAS Registry Number.

Tubes, dumbbells, and pyramids: A crystalline, large-pore, microporous semiconductor, |Rb18| [Sb36O54][(SbTe 3)2(Te2)6] (Rb-CTH-1), which consists of an 18-ring {Sb18O27} tubular unit surrounded by an intricate, ordered arrangement of trigonal-pyramidal {SbTe 3}3- ions and Te22- dumbbells and lined with Rb+ ions, has been prepared (see picture; turquoise R). This semiconductor has a band gap of approximately 850 meV. (Figure Presented).

Oxidation of tellurium(IV) by tetrabutylammonium tribromide

Kalantre,Gokavi

, p. 2048 - 2050 (2007/10/03)

The reaction between tetrabutylammonium tribromide and tellurium(IV) has been studied in 50% (v/v) acetic acid under second order conditions. The overall order of reaction is found to be two, unity each in both the reactants. The reaction involves a direct two-electron transfer step since the test for the formation of free radicals due to single electron step was negative. The reaction is retarded by hydrogen ions due to protonation prior equilibria of the reductant, tellurium(IV). The active species of the reactants is found to be tribromide ion of the oxidant and HTeO3- of the reductant. Considerable decrease in the entropy of activation of the reaction indicates formation of an ordered transition state between the two reactants analogous to that in alcohol oxidation by tetrabutylammonium tribromide ion.

125Te and 19F NMR spectroscopic study of the hydrolysis of pentafluorotellurium chloride: evidence for trans- and cis-HOTeF4Cl and cis,mer-(HO)2TeF3Cl

Lawlor, Lawrence J.,Martin, Alban,Murchie, Michael P.,Passmore, Jack,Sanders, Jeremy C. P.

, p. 1501 - 1505 (2007/10/02)

The hydrolysis of TeF5Cl has been followed by (125)Te and (19)F NMR spectroscopy.The spectra show that the known series (HO)nTeF(6-n) (n=2-6) are present.In addition the spectra are consistent with the presence of the previously unreported series (HO)nTeF(5-n)Cl (n=1-3) as well as unidentified fluorotellurium(IV) species.Evidence is presented for the new species trans- ans cis-HOTeF4Cl and cis,mer-(HO)2TeF3Cl.The course of the hydrolysis of TeF5Cl is compared with that of SF5Cl. Key words: trans-tetrafluorotellurium hydroxychloride, cis-tetrafluorotellurium hydroxychloride, cis,mer-tetrafluorotellurium dihydroxychloride, pentafluorotellurium chloride, hydrolysis.
