Aluminum chloride hexahydrate
CAS No.:7784-13-6,
Molecular Weight: 241.43,
Chemical Formula: AlCl3·6H2O

Aluminum chloride anhydrous
CAS No.:7446-70-0,
Molecular Weight: 134.34,
Chemical Formula: AlCl3

Aluminum Chloride Hexahydrate Grade 1
AlCl3·6H2O 241.43
Aluminum chloride, hexahydrate.
Aluminum chloride hexahydrate [7784-13-6].
Assay: 98% minimum AlCl3 on dry basis.
Water: between 42.0% and 48.0%.
Sulfate— The addition of 0.2 mL of barium chloride TS to 10 mL of a solution (1 in 100) produces no turbidity within 1 minute.
Limit of alkalies and alkaline earths— To a boiling solution of 1.0 g in 150 mL of water add a few drops of methyl red TS, then add 6 N ammonium hydroxide until the color of the solution just changes to a distinct yellow. Add hot water to restore the volume to 150 mL, and filter while hot.
Evaporate 75 mL of the filtrate to dryness, and ignite to constant weight: the weight of the residue does not exceed 2.5 mg (0.5%).
Heavy metals, Method — the limit is 0.002%.
Iron — 0.001%.

Aluminum Chloride Hexahydrate Grade 2
AlCl3·6H2O 241.43

Assay: 95.5% minimum on dry basis
Fe: 0.025% max
Water insoluble: 0.1% max
Pb: 0.0005% max

Packing: 25kgs net new plastic woven bag1x20'FCL=20mts with pallet.

Aluminium Chloride Hexahydrate BP Grade Ph Eur

AlCl3,6H2O -- 241.4 -- 7784-13-6

DEFINITION
Content: 95.0 per cent to 101.0 per cent.

CHARACTERS
Appearance: White or slightly yellow, crystalline powder or colourless crystals, deliquescent.
Solubility: Very soluble in water, freely soluble in ethanol (96 per cent), soluble in glycerol.

IDENTIFICATION
A. Dilute 0.1 ml of solution S2 (see Tests) to 2 ml with water. The solution gives reaction of chlorides.
B. Dilute 0.3 ml of solution S2 to 2 ml with water. The solution gives the reaction of aluminium.

TESTS
Solution S1: Dissolve 10.0 g in distilled water and dilute to 100 ml with the same solvent.
Solution S2: Dilute 50 ml of solution S1 to 100 ml with water.
Appearance of solution: Solution S2 is clear and not more intensely coloured than reference solution.
Sulphates: Maximum 100 ppm, determined on solution S1.
Iron: Maximum 10 ppm, determined on solution S1.
Alkali and alkaline-earth metals: Maximum 0.5 per cent.
Heavy metals: Maximum 20 ppm.
Water: 42.0 per cent to 48.0 per cent, determined on 50.0 mg.

ASSAY
Dissolve 0.500 g in 25.0 ml of water. Carry out the complexometric titration of aluminium. Titrate with 0.1 M zinc sulphate until the colour of the indicator changes from greyishgreen to pink. Carry out a blank titration. 1 ml of 0.1 M sodium edetate is equivalent to 24.14 mg of AlCl3,6H2O.

Aluminum Chloride USP Grade

AlCl3·6H2O -- 241.43 -- [7784-13-6].

Aluminum Chloride contains not less than 95.0 percent and not more than 102.0 percent of AlCl3, calculated on the anhydrous basis.

Identification: A solution (1 in 10) responds to the tests for Aluminum and for Chloride.
Water: Between 42.0% and 48.0%.
Sulfate: The addition of 0.2 mL of barium chloride to 10 mL of a solution (1 in 100) produces no turbidity within 1 minute.
Limit of alkalies and alkaline earths: the limit is 0.5%.
Heavy metals: the limit is 0.002%.
Iron: the limit is 0.001%.
