-Aluminum alkoxide chemistry uses of n-Eicosyl alcohol, aluminum salt:
The most direct application of n-Eicosyl alcohol, aluminum salt is as a long-chain aluminum alkoxide and chemical intermediate.
Its aluminum-alkoxide functionality makes n-Eicosyl alcohol, aluminum salt relevant to reactions in which an organoaluminum alkoxide is required.
The C20 chains make n-Eicosyl alcohol, aluminum salt particularly different from low-molecular-weight aluminum alkoxides such as aluminum isopropoxide or aluminum ethoxide.
-Hydrophobic surface modification uses of n-Eicosyl alcohol, aluminum salt:
The three C20 hydrocarbon chains provide strong hydrophobic character.
Consequently, n-Eicosyl alcohol, aluminum salt can be of interest in specialty systems designed to modify surface:

Long-chain aluminum compounds can therefore be relevant to specialty lubricant and grease formulations.
However, it is important not to confuse aluminum alkoxides with aluminum soaps, which are widely established grease thickeners.
For CAS 67905-31-1 specifically, I did not find sufficiently strong primary-source evidence to describe it as a mainstream commercial grease thickener.
-Rheology modification uses of n-Eicosyl alcohol, aluminum salt:
The combination of a metal center and three long hydrocarbon chains may allow n-Eicosyl alcohol, aluminum salt to influence the structure of nonpolar formulations.
Potential effects include modification of:

BENEFITS of N-EICOSYL ALCOHOL, ALUMINUM SALT:
The structural benefits of N-Eicosyl alcohol, aluminum salt include:
Strong hydrophobic character:
Three C20 chains provide substantial water-repellent character.
Low volatility:
The high molecular weight and long chains reduce volatility at ambient temperature.
High hydrocarbon compatibility:
n-Eicosyl alcohol, aluminum salt has strong affinity for oils, waxes and other nonpolar materials.
Metal-alkoxide functionality:
The aluminum-oxygen center provides chemical reactivity unavailable in ordinary eicosanol.
Long-chain surface activity:
The long hydrocarbon groups can influence interfacial and surface behavior.
Specialty material functionality:
n-Eicosyl alcohol, aluminum salt combines organic hydrocarbon characteristics with aluminum-organic chemistry.
High molecular weight:
The molecular weight of n-Eicosyl alcohol, aluminum salt is approximately 919.6 g/mol.
Potential organic-inorganic compatibility:
The aluminum center and long hydrocarbon chains can provide a useful combination for specialized surface and materials chemistry.
CHEMICAL STRUCTURE of N-EICOSYL ALCOHOL, ALUMINUM SALT:
n-Eicosyl alcohol, aluminum salt can be represented as: Al(OC20H41)3
This means that one aluminum center is associated with three eicosanolate groups.
Each eicosanolate group originates from 1-eicosanol and contains a straight, saturated C20 hydrocarbon chain.
The three long hydrocarbon chains account for much of n-Eicosyl alcohol, aluminum salt's hydrophobic character.
The aluminum-oxygen portion provides the chemically reactive metal-alkoxide functionality.
This combination makes n-Eicosyl alcohol, aluminum salt substantially different from ordinary aluminum inorganic salts such as aluminum chloride or aluminum sulfate.
IMPORTANT NOTE ABOUT PHYSICAL DATA of N-EICOSYL ALCOHOL, ALUMINUM SALT:
There is a significant difference between the amount of information available for 1-eicosanol itself and for 1-eicosanol, aluminum salt.
Measured physical properties for the parent alcohol 1-eicosanol (CAS 629-96-9), including a melting point of approximately 64–68 °C and boiling-point data around 309–372 °C.
These values must not be presented as measured properties of n-Eicosyl alcohol, aluminum salt.
For CAS 67905-31-1, the publicly accessible databases provide calculated thermal values but comparatively little experimentally measured physical-property data.
WATER SOLUBILITY AND HYDROPHOBICITY of N-EICOSYL ALCOHOL, ALUMINUM SALT:
N-Eicosyl alcohol, aluminum salt contains three very long hydrocarbon chains.
Each chain contains 20 carbon atoms and is completely saturated.
Consequently, n-Eicosyl alcohol, aluminum salt has a very large hydrophobic component.
The aluminum-alkoxide center does not make the entire molecule water-soluble because the three long hydrocarbon chains dominate the overall physical character.
n-Eicosyl alcohol, aluminum salt should therefore be considered practically insoluble or extremely poorly soluble in water.
A precise numerical water-solubility value for CAS 67905-31-1 was not located in the authoritative sources reviewed, so a numerical value should not be invented.
MOISTURE REACTIVITY of N-EICOSYL ALCOHOL, ALUMINUM SALT:
The aluminum-alkoxide functional group is susceptible to hydrolysis by water.
Exposure to moisture can break aluminum-oxygen bonds and generate hydrolysis products involving aluminum and the corresponding long-chain alcohol.
This is an important characteristic of the aluminum-alkoxide family.
Therefore, n-Eicosyl alcohol, aluminum salt should generally be protected from:
Water.
High humidity.
Condensation.
Wet processing conditions.
Uncontrolled contact with aqueous formulations.
This moisture sensitivity is particularly relevant when n-Eicosyl alcohol, aluminum salt is supplied as a dry specialty chemical.
THERMAL CHARACTERISTICS of N-EICOSYL ALCOHOL, ALUMINUM SALT:
The calculated boiling point of approximately 309 °C indicates that n-Eicosyl alcohol, aluminum salt has very low volatility under ordinary ambient conditions.
n-Eicosyl alcohol, aluminum salt's large molecular size results from the three C20 hydrocarbon chains.
n-Eicosyl alcohol, aluminum salt should not, however, be assumed to be suitable for simple high-temperature distillation merely because a calculated boiling point is reported.
Aluminum alkoxides can undergo chemical changes at elevated temperatures, and actual thermal stability should therefore be evaluated using the supplier's thermal-analysis data when processing at high temperature.
CHEMICAL REACTIVITY of N-EICOSYL ALCOHOL, ALUMINUM SALT:
The most important reactive feature is the Al–O–C alkoxide functionality.
n-Eicosyl alcohol, aluminum salt can undergo chemistry characteristic of aluminum alkoxides, particularly:
Hydrolysis.
Alcohol exchange/transalkoxylation.
Coordination reactions.
Surface reactions.
Reactions involving moisture.
The C20 hydrocarbon groups themselves are chemically relatively unreactive because they are saturated straight-chain alkyl groups.
Therefore, most of the distinctive chemical reactivity is associated with the aluminum-oxygen portion
CHARACTERISTICS of N-EICOSYL ALCOHOL, ALUMINUM SALT:
N-Eicosyl alcohol, aluminum salt can be characterized as:
A long-chain aluminum alkoxide.
A metal-organic aluminum compound.
A high-molecular-weight material.
A hydrophobic substance.
A low-volatility substance.
A moisture-sensitive material.
A specialty chemical intermediate.
A compound containing three C20 saturated hydrocarbon chains.
