Indium Acetate: What Is It? How Does it Work?

Physical properties of indium acetate

CAS number: 25114-58-3

Molecular formula: In. (C2H3O2)3

Molecular weight: 291.95

Properties: White needle-like crystals.

Melting point: 280℃

Purity: 99.99%;

Soluble in mineral acids and acetic acid

Craft:

1) Concentrated acetic acid reacts with indium (III) hydroxide;

2) Indium acetate reacts with acetic acid in the environment of hydrogen peroxide to form indium acetate.

Synthetic method of indium acetate

The indium(III) hydroxide was dissolved in a minimum volume of concentrated acetic acid heated to 70°C, filtered and evaporated to obtain white crystals with a melting point of 280°C.

Indium acetate (III) can also be synthesized by reacting indium with acetic acid in the presence of hydrogen peroxide.

How to store indium acetate?

Keep the receptacle sealed

Put in a tight receptacle and store in a cool, dry place

Stability of Indium Acetate

Will not decompose if used and stored according to specifications. Can be recrystallized from aqueous acetic acid. With pyridine, ethylenediamine, tetramethylammonium hydroxide, etc., to obtain adducts.
