Justification for type of information:

Peer-viewed handbook

Key result

Remarks on result:

not determinable

Remarks:

React with water

Details on results:

Anhydrous aluminum chloride reacts extremely violently with water, evolving hydrogen chloride. The hexahydrate, AlCl3•6H2O is formed in this reaction. In aqueous solution, aluminum chloride is partially hydrolyzed to hydrochloric acid and aluminum oxychloride. For this reason, anydrous aluminum chloride cannot be obtained by concentrating the solution and carcining the hydrate.

Conclusions:

The solubility of anhydrous aluminum chloride is not determined, because this substance reacts violently with water evolving hydrogen chloride to form hydrate.

Executive summary:

Anhydrous aluminum chloride reacts with water. It is not possible to determine the solubility.

Endpoint:

water solubility

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours)

Justification for type of information:

These data are peer-reviewed handbook and publication.

Deviations:

yes

Remarks:

Because of high dissolution heat, saturated solution was not prepared.

Principles of method if other than guideline:

The aliquot amount of substance was dissolved into 100 ml water in nitrogen atmosphere and checked it by visual inspection.

GLP compliance:

no

> 250 g/L

Conc. based on:

test mat.

Temp.:

25 °C

pH:

Details on results:

The test was carried out by preparing 5% and 25% aqeuous solution under nitrogen atmosphere. These solutions were exposured to air in Erlenmeyer flasks. On exposure to air, these solution generated precipates as time passes.

Decomposition of TiCl3-AA (Aluminum trititanium dodecachloride)

 

Run	Initial Sample concentration	Decomposition ratio (%)
		After preparation	1 day after	3 day after
1	5 wt%	9.75	33.93	50.18
2	5 wt%	6.33	31.41	46.43
3	25 wt%	3.69	12.03	16.21
4	25 wt%	7.91	16.12	20.95

 

Conclusions:

Aluminum trititanium dodecachloride dissolved into water with large amount heat emission under nitrogen atmosphere. For the sake of safety, more than 25 wt% aqueous solution was not prepared. On exposure to air, the solutions became tubid and finally gave precipitates as time passed.

Executive summary:

The solubility of aluminum trititanium dodecachloride was more than 25 wt%, but on exposure to air, the substance gradually decomposed to give precipitates.

Description of key information

Aluminum trititanium dodecachloride dissolved into water more than 25 wt% under nitrogen atmosphere.

But in contact with air, the substance in water gradually decomposed and gave precipitates as described in the literature.

Aluminum trititanium dodecachloride composes of aluminum chloride and titanium trichloride.

Both components are known to react with water found in the handbook. Titanium trichloride react with water to form hydrate and partially decomposes to produce hydrogen chloride and titanium oxide. Aluminum chloride also reacts with water to form hydrate and partially decomposes to hydrogen chloride and oxyaluminum chloride.

Additional information

Aluminum trititanium dodecachloride (TiCl3 -AA) dissolved into water with emission of large amount of heat.

For sake of safety, solubility test more than 25 wt% was not carried out.

The solubility of TiCl3 -AA in water seems to be more than 250 g/L under inert atmosphere.

In contact with air, the solution became tubid and finally gives precipitates.
