Definition
Different sources of media describe the Definition of 139-12-8 differently. You can refer to the following data:
1. A salt obtained by reaction of aluminum hydroxide and acetic acid with subsequent recrystallization. Its neutral form Al(C 2 H 3 O 2 ) 3 is a white, water-soluble powder used in solution as an antiseptic, astringent, and antiperspirant. Its basic form is Al(C 2 H 3 O 2 ) 2 OH, also known as aluminum diacetate and aluminum subacetate. It is a crystalline solid, insoluble in water, used as a mordant in textile dyeing, as a flame retardant and waterproofing agent, and in manufacture of lakes and pigments.
2. (aluminum acetate; Al(OOCCH3)3) A white solid soluble in water. It is usually obtained as the dibasic salt, basic aluminum ethanoate, Al(OH)(CH3COO)2. It is prepared by dissolving aluminum hydroxide in ethanoic acid and is used extensively as a mordant in dyeing and as a size for paper and cardboard products. The solution is hydrolyzed and contains various complex aluminumhydroxyl species and colloidal aluminum hydroxide.
Application
The diacetate is used as an antiseptic. The Aluminum Acetate compound can be used medicinally to treat infections in the outer ear canal. It is used in the name brand drug Domeboro, which contains acetic acid/aluminum acetate.This medication kills the infectious bacteria and fungus as well as drying out the ear canal. Since it acts as a drying agent, it can also be used in the treatment of severe rashes, such as poison ivy, poison oak, and poison sumac.
Production Methods
Ammonium acetate is produced by the neutralization of acetic acid with ammonium carbonate or by saturating glacial acetic acid with dry ammonia gas. Obtaining crystalline ammonium acetate is difficult on account of its aqueous solution giving off ammonia when evaporated.
Brand name
Buro-Sol Concentrate (Doak); Domeboro (Bayer).
Industrial uses
As the salt of a weak acid and a weak base, ammonium acetate has a number of distinctive properties. NH4C2H3O2 is occasionally employed as a biodegradable deicing agent. It is often used with acetic acid to create a buffer solution, one that can be thermally decomposed to non-ionic products Ammonium acetate is useful as a catalyst in the Knoevenagel condensation and as a source of ammonia in the Borch reaction in organic synthesis. It is a relatively unusual example of a salt that melts at low temperatures.Can be used with distilled water to make a protein precipitating reagent. Is often used as an aqueous buffer for ESI mass spectrometry of proteins and other molecules. Ammonium acetate is volatile at low pressures. Because of this it has been used to replace cell buffers with non-volatile salts, in preparing samples for mass spectrometry.It is also popular as a buffer for mobile phases for HPLC with ELSD detection for this reason. Other volatile salts that have been used for this include ammonium formate.
Synthesis
The triacetate forms when aluminum sulfate is mixed with barium acetate. Another synthetic method is by bringing together aluminum hydroxide, acetic anhydride and glacial acetic acid in water, forming the basic aluminum monoacetate The diacetate is prepared in a reaction of sodium aluminate (NaAlO2) with acetic acid.
Check Digit Verification of cas no
The CAS Registry Mumber 139-12-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139-12:
(5*1)+(4*3)+(3*9)+(2*1)+(1*2)=48
48 % 10 = 8
So 139-12-8 is a valid CAS Registry Number.

Acid-Mediated Synthesis of Ordered Mesoporous Aluminosilicates: The Challenge and the Promise
Krishna, Nunna V.,Selvam, Parasuraman

A new intrinsic hydrolysis method was employed, for the first-time, to synthesize well-ordered H-AlSBA-15 with trivalent aluminium exclusively in the tetrahedral framework structure of SBA-15. Unlike other methods, which involve incorporation of aluminium ions in both the framework (Br?nsted) and non-framework (Lewis) sites of the silicate matrix, the intrinsic hydrolysis method isomorphously substitutes aluminium ions in the tetrahedral network even at high aluminium content. This unique approach relies mainly on the hydrolysis rates of the inorganic (silicon and aluminium) precursors used for the preparation in such a way that the condensation occurs simultaneously so as to overcome the usually encountered difficulties in stabilizing aluminium ions in the silicate matrix. In this way, we could successfully synthesize high quality Br?nsted acidic H-AlSBA-15, hitherto not reported. The synthesized materials were systematically characterized by various analytical, spectroscopic, and imaging techniques, including XRD, Brunauer–Emmett–Teller (BET) surface area measurements, TEM, SEM,29Si and27Al magic angle spinning NMR spectroscopy, X-ray fluorescence (XRF), and NH3temperature-programmed desorption (TPD). The characterization results reveal the presence of a highly porous structure (with narrow pores) and tetrahedrally coordinated trivalent aluminium in the silicate matrix with more medium to strong Br?nsted acid sites. The resulting high quality catalysts exhibit excellent activity for tert-butylation of phenol with high selectivity towards para-tert-butyl phenol and 2,4-di-tert-butyl phenol.

Quantum dot light emitting diodes (QLEDs) are rising as a promising light emitting technology. However, the widely used insulating organic ligands hamper carrier injection. Herein, we developed a bi-inorganic-ligand strategy to replace organic ligands and dispersed QDs in a benign solvent butylamine. The all-inorganic QD film shows enhanced luminescence intensity and superior thermal stability and conductivity. In the end, we exploited the first prototype all inorganic QLED.
Oxygen activation on metallic centers and oxidizing abilities of such oxygen

, p. 1265 - 1268 (2007)
It was shown that metallcontaining peroxides such as XOOOBu-t [X = (t-BuO)2Al, (t-BuO)3Ti] generate molecular oxygen in the electron-excited singlet state (1O2). These ozonides and η2-peroxocomplex Ph3Bi(η2O2) demonstrate high oxidative activity towards some classes of organic substances under mild conditions (20 °C).
Liquid-phase oxidation of sulfides by an aluminum (and titanium) tert-butoxide - tert-butyl hydroperoxide system
Dodonov,Zaburdaeva,Stepovik
, p. 1729 - 1734 (2007/10/03)
A system aluminum (and titanium) tert-butoxide-tert-butyl hydroperoxide (1 : 2) under mild conditions (20°C, 1 h) oxidizes aliphatic and alkylaromatic sulfides and diphenyl sulfide to the corresponding sulfones in yields close to ～100%. The oxidation is induced by electron-excited dioxygen formed upon thermal decomposition of intermediate metal-containing peroxy trioxides (ozonides). The latter are formed as a result of the reversible reaction of aluminum or titanium tert-butoxides with tert-butyl hydroperoxide followed by the interaction of di-tert-butoxy-tert-butylperoxyaluminum and tri-tert-butoxy-tert-butylperoxytitanium that formed with another Bu tOOH molecule. Alkminum-containing peroxide (ButO) 2AlOOBut oxidizes sulfides to sulfoxides.
