Description
Aluminum acetylacetonate, also known as alumunium acetylacetonate, is a white to yellow powder or crystalline compound that is insoluble in water but soluble in organic solvents. It is stable and incompatible with strong oxidizing agents. It can be prepared by reacting AlCl3 and acetylacetonate. Aluminum acetylacetonate is an important organic intermediate used in the synthesis of substituted acetylacetonate products.

Health Hazard
Exposures to aluminium (III) acetylacetonate cause adverse health effects. Exposures by
inhalation, ingestion, and through skin contact are harmful. It causes irritation effects
to the eyes, skin, and respiratory tract. Aluminium (III) acetylacetonate may release
2,4-pentanedione, which is a suspected teratogen and causes neurological health effects
and harm to the unborn child. However, toxicology is not fully investigated.
Flammability and Explosibility
Nonflammable
Purification Methods
Recrystallise it several times from *benzene or aqueous MeOH, 216 and 286mn. max [Charles & Pawlikowski J Phys Chem 62 440 1958.] It can be purified by sublimation and has the following solubilities in g percent: *C6H6 35.9 (20o), 47.6 (40o), toluene 15.9 (20o), 22.0 (40o) and acetylacetone 6.6 (20o), 10.4 (40o).

Check Digit Verification of cas no
The CAS Registry Mumber 13963-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13963-57:
(7*1)+(6*3)+(5*9)+(4*6)+(3*3)+(2*5)+(1*7)=120
120 % 10 = 0
So 13963-57-0 is a valid CAS Registry Number.

Acid-Mediated Synthesis of Ordered Mesoporous Aluminosilicates: The Challenge and the Promise

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.
