ble in water and polar organic solvents; relatively
insoluble in nonpolar organic solvents. Strong acid.
Noncombustible.
Uses
Different sources of media describe the Uses of 12027-43-9 differently. You can refer to the following data:
1. Catalyst for organic synthesis, minerals separation, reagent for alkaloids.Tungstosilicic acid hydrate is used to prepare ethylacetate and acetic acid from ethylene. It is used in the preparation of silicotungstate butylmethylimidazolium bromide and charge transfer compounds with Keggin anions. It is also used in catalyst preparation, which is useful for catalytic liquid-phase oxidation of xylene. Further, it acts as a mediator in production of hydrogen through electrolysis of water.
2. Reactant for Preparation of silicotungstate butylmethylimidazolium bromide ionic liquid hybrid material, Synthesis of SnII-substituted Keggin-type polyoxometalates as photocatalysts, Preparation of silicotungstic acid/organically modified silane proton-conducting membranes3, Preparation of charge transfer compounds with Keggin anions, Preparation of catalyst for catalytic liquid-phase oxidation of xylene
Purification Methods
Extract the acid with diethyl ether from a solution acidified with HCl. The diethyl ether is evaporated under vacuum, and the free acid is crystallised twice [Matijevic & Kerker J Phys Chem 62 1271 1958].
Check Digit Verification of cas no
The CAS Registry Mumber 12027-43-9 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 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12027-43:
(7*1)+(6*2)+(5*0)+(4*2)+(3*7)+(2*4)+(1*3)=59
59 % 10 = 9
So 12027-43-9 is a valid CAS Registry Number.
