USES and APPLICATIONS of N-TETRACOSYL ALCOHOL, ALUMINUM SALT:
N-Tetracosyl alcohol, aluminum salt can be considered a specialty aluminum-organic intermediate.
n-tetracosyl alcohol, aluminum salt can potentially be used as a precursor for aluminum-containing materials.
Its aluminum alkoxide functionality makes n-tetracosyl alcohol, aluminum salt chemically suitable for hydrolysis and subsequent formation of aluminum–oxygen-containing materials.
n-tetracosyl alcohol, aluminum salt can potentially be investigated as an aluminum precursor in sol-gel-type chemistry.
Long-chain aluminum alkoxides can be useful in research involving controlled hydrolysis and condensation of aluminum-containing precursors.
The C24 alkyl groups can modify the hydrophobicity and surface characteristics of materials generated from the precursor.
n-tetracosyl alcohol, aluminum salt can therefore be of interest in surface-modification research.
n-tetracosyl alcohol, aluminum salt may also be investigated for preparation of hydrophobic aluminum-containing surfaces.
The long hydrocarbon chains can potentially impart water-repellent characteristics to treated surfaces.
n-tetracosyl alcohol, aluminum salt may be relevant to specialty coatings or surface-treatment systems in which a hydrophobic organic component and an aluminum-containing component are desired.
n-tetracosyl alcohol, aluminum salt may also serve as a research intermediate for preparing other aluminum-organic materials through ligand-exchange or hydrolysis reactions.
Long-chain aluminum alkoxides are technically interesting because the organic ligand can influence the morphology, surface energy and compatibility of the resulting aluminum-containing material.
However, there is insufficient evidence to describe n-tetracosyl alcohol, aluminum salt specifically as a commonly used commercial lubricant additive, surfactant, cosmetic ingredient, pharmaceutical ingredient, food additive or pesticide.
n-tetracosyl alcohol, aluminum salt finds applications in materials science to create thin-film lipid layers, surface coat modifiers, and thickeners in industrial lubricant oils.
Furthermore, n-tetracosyl alcohol, aluminum salt serves as a catalyst component or functional group donor in polymer engineering, where high-purity linear long-chain structures are required.
BENEFITS AND TECHNICAL ADVANTAGES of N-TETRACOSYL ALCOHOL, ALUMINUM SALT:
The principal technical advantage of N-Tetracosyl alcohol, aluminum salt is its combination of a reactive aluminum alkoxide center with three long C24 hydrocarbon chains.
The C24 chains provide strong hydrophobic character.
n-tetracosyl alcohol, aluminum salt has very high molecular weight.
Its high molecular weight contributes to extremely low volatility.
The long hydrocarbon chains can improve compatibility with hydrophobic organic phases.
The aluminum alkoxide functionality provides a route to aluminum-containing inorganic materials through hydrolysis and condensation.
n-tetracosyl alcohol, aluminum salt can therefore provide an organic–inorganic connection between a hydrophobic organic environment and an aluminum-containing phase.
The long alkyl groups can potentially modify surface energy.
They can potentially increase water repellency when incorporated into appropriate surface-treatment systems.
n-tetracosyl alcohol, aluminum salt's low volatility may be useful in processes where evaporation of the organic component is undesirable.
n-tetracosyl alcohol, aluminum salt's moisture sensitivity can also be exploited in controlled hydrolysis processes where an aluminum-containing material is intentionally generated.
MOLECULAR STRUCTURE of N-TETRACOSYL ALCOHOL, ALUMINUM SALT:
The idealized structure can be represented as: Al(OC24H49)3
Each tetracosanolate chain contains 24 carbon atoms.
The three alkoxide groups contribute: 3 × C24H49O
Together with aluminum, this gives: C72H147AlO3
The aluminum center is formally associated with three alkoxide oxygen atoms.
The three long hydrocarbon chains dominate the physical behavior of n-tetracosyl alcohol, aluminum salt and make it substantially more hydrophobic and less volatile than short-chain aluminum alkoxides.
The structural formula also explains why n-tetracosyl alcohol, aluminum salt has a very high molecular weight of approximately 1087.93 g/mol.
CHEMICAL CHARACTERISTICS of N-TETRACOSYL ALCOHOL, ALUMINUM SALT:
N-Tetracosyl alcohol, aluminum salt is characterized by the coexistence of a reactive aluminum alkoxide center and three very long saturated hydrocarbon chains.
The C24 chains make the compound strongly hydrophobic.
The aluminum–oxygen portion gives the material chemical reactivity toward water and other protic substances.
n-tetracosyl alcohol, aluminum salt is therefore fundamentally different from a conventional water-soluble aluminum salt.
n-tetracosyl alcohol, aluminum salt should instead be regarded as a moisture-sensitive metal-organic alkoxide.
n-tetracosyl alcohol, aluminum salt's three long hydrocarbon chains can provide strong compatibility with nonpolar organic environments.
The long chains also contribute to n-tetracosyl alcohol, aluminum salt's low vapor pressure and high molecular weight.
n-tetracosyl alcohol, aluminum salt has no aromatic rings and no unsaturated carbon-carbon bonds.
n-tetracosyl alcohol, aluminum salt's carbon framework is entirely aliphatic and saturated.
n-tetracosyl alcohol, aluminum salt therefore combines a hydrophobic organic component with an inorganic aluminum-containing functionality.
HYDROLYSIS AND REACTIVITY of N-TETRACOSYL ALCOHOL, ALUMINUM SALT:
Hydrolysis is one of the most important chemical characteristics of N-Tetracosyl alcohol, aluminum salt.
When exposed to water, the aluminum–oxygen–carbon bonds of the alkoxide can undergo hydrolysis.
The overall reaction can be represented schematically as:
Al(OC24H49)3 + 3H2O → Al(OH)3 + 3C24H49OH
This equation represents the idealized complete hydrolysis pathway; the actual products can depend on water availability, reaction conditions and subsequent condensation reactions.
The organic hydrolysis product is 1-tetracosanol.
The aluminum-containing products may subsequently undergo dehydration and condensation processes to form other aluminum–oxygen species.
