12026-28-7 Usage

Uses

Metatitanic acid is an intermediate product in the production of titanium dioxide using the sulfuric acid method. It can also be used as a matting agent for chemical fibers, a catalyst and an adsorbent for uranium in seawater.

Production Methods

Ilmenite reacts with sulfuric acid to generate titanyl sulfate, which is purified, frozen to remove ferrous sulfate, filtered by pressure and concentrated, and then hydrolyzed by titanyl sulfate, washed with water, filtered and dried to give metatitanic acid.FeTiO3+3H2SO4→FeSO4+Ti(SO4)2+3H2OFeTiO3+2H2SO4→FeSO4+TiOSO4+2H2OTi(SO4)2+H2O→TioSO4+H2SO4TiOSO4+2H2O→H2TiO3+H2SO4

Check Digit Verification of cas no

The CAS Registry Mumber 12026-28-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,2 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12026-28:
(7*1)+(6*2)+(5*0)+(4*2)+(3*6)+(2*2)+(1*8)=57
57 % 10 = 7
So 12026-28-7 is a valid CAS Registry Number.

Reactions of titanium oxides with water molecules. A matrix isolation FTIR and density functional study

Shao, Limin,Zhang, Luning,Chen, Mohua,Lu, Hao,Zhou, Mingfei

, p. 178 - 184 (2001)

Reactions of titanium dioxides with water molecules have been studied by matrix isolation infrared and density functional theoretical calculations. In solid argon, titanium dioxide molecules reacted with water to form OTi(OH)2 molecules spontaneously on annealing. The potential energy surface along the TiO2+H2O→OTi(OH)2 reaction path was calculated. Although titanium dioxide-water complex was predicted to be stable, this complex was not observed due to low energy barrier and high exothermicity for the hydrolysis reaction. Evidence is also presented for the formation of OTi-OH2 complex.

Metatitanic acid pseudomorphs after titanyl sulfates: Nanostructured sorbents and precursors for crystalline titania with desired particle size and shape

Klementova, Mariana,Motlochova, Monika,Boha?ěk, Jaroslav,Kupcí k, Jaroslav,Palatinus, Lukas,Plizingrova, Eva,Szatmary, Lorant,Sǔbrt, Jan

, p. 6762 - 6769 (2017)

A new preparation method for the synthesis of TiO2 microrods in aqueous media starting with solid hydrated titanyl sulfate crystals with defined morphology is presented. The method is based on the extraction of sulfate ions from the crystals and their replacement with hydroxyl groups in aqueous ammonia solution leaving the Ti?O framework intact. The particle size and morphology of the starting hydrated titanyl sulfate is closely preserved in the pseudomorphs of amorphous metatitanic acid including such details like the layered structure of the original hydrated titanyl sulfate crystals. When annealed up to 1200 °C, the rod-like morphology of particles is retained, while the phase composition changes to anatase/rutile. The rod-like particles of metatitanic acid possess excellent sorption properties toward radionuclides. The mechanism of pseudomorph formation is discussed based on the structures of the precursors, including the hitherto unknown structure of titanyl sulfate dihydrate determined by electron diffraction tomography.
