Description
Aluminum ethoxide, also known as aluminum ethylate, is a chemical compound with the formula Al(OC2H5)3. It is a colorless liquid that slowly solidifies to a white powder and is sensitive to moisture. Aluminum ethoxide is prepared from a reaction of aluminum (Al) with ethanol in the presence of catalytic amounts of iodine (I2) and mercuric chloride (HgCl2). It is a versatile compound with various applications in different industries.
Uses
1. Used in Chemical Synthesis:
Aluminum ethoxide is used as a reducing agent for aldehydes and ketones, facilitating the conversion of these compounds into alcohols. This property makes it a valuable reagent in the synthesis of various organic compounds.
2. Used as a Catalyst in Polymerization:
Aluminum ethoxide serves as an effective catalyst in the polymerization process, promoting the formation of high molecular weight polymers. Its catalytic activity is crucial in the production of various polymers with specific properties and applications.
3. Used in the Sol-Gel Process:
Aluminum ethoxide is employed in the sol-gel process for the preparation of high purity aluminum sesquioxide (alumina). This process involves the transition from a liquid "sol" into a solid "gel" phase, and aluminum ethoxide plays a key role in controlling the reaction and producing high-quality alumina.
4. Used in the Reduction of Carbonyl Compounds:
Aluminum ethoxide is also used as a reducing reagent for carbonyl compounds, which are restored to alcohols. This application is particularly useful in the synthesis of complex organic molecules and pharmaceutical compounds.

Purification Methods
Crystallise it from CS2 [m 139o, CS2 complex] and distil it in a vacuum. The molecular weight corresponds to [Al(OEt)3]4 [Robinson & Peak J Phys Chem 39 1127 1935, Vilani & Nord J Am Chem Soc 69 2605 1947]. [Beilstein 1 H 313, 1 I 158, 1 II 3008, 1 III 1284, 1 IV 1289.]
Check Digit Verification of cas no
The CAS Registry Mumber 555-75-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 555-75:
(5*5)+(4*5)+(3*5)+(2*7)+(1*5)=79
79 % 10 = 9
So 555-75-9 is a valid CAS Registry Number.

Paragraph 0038-0040; 0053; 0054, (2019/11/20)
The invention discloses a method for removing iron impurities in alkoxy aluminum. The method comprises the steps that supporting electrolyte is added in an alcoholic solution of the alkoxy aluminum, an electrolyte is formed by mixing evenly, an aluminum electrode is inserted into the electrolyte as a cathode, an inert electrode is used as an anode, an electrolytic reaction is conducted at the temperature being +/-80 DEG C of the boiling point of an alcoholic solution of the alkoxy aluminum, and a high-purity alcoholic solution of the alkoxy aluminum is obtained after the reaction. According tothe method, an electrolytic method is used for removing the iron impurities in the alkoxy aluminum, operation is easy, and the effect is good.

Solutions of aluminum alkoxides obtained by interaction of aluminum metal with methyl, ethyl, and isopropyl alcohols were studied by 27Al and 13C NMR and small-angle X-ray scattering. Alkoxides with a tetrahedral environment of aluminum prevail in methanol solutions, and those with an octahedral environment of aluminum predominate in ethanol solutions. In isopropyl alcohol at 293 K, polynuclear alkoxides with tetrahedral, octahedral, and pentacoordinated aluminum environments coexist. The structure of polynuclear complexes was refined by comparison of their calculated dimensions with small-angle X-ray scattering data.
