Does lithium acetate dihydrate dissolve in water?

Lithium acetate dihydrate (CH3COOLi) is a salt of acetic acid and lithium. It is used in the preparation of the modified ninhydrin reagent for amino analysis by ion-exchange chromatography, as an anticorrosion agent in molding polyphenylene sulfide resins, and as a catalyst in alkyd resin and acrylic polymer production.

Solubility in water

Lithium acetate is soluble in aqueous solutions at room temperature and under normal conditions of storage. It is essentially deliquescent, but should be stored in tightly closed containers.

Sodium acetate, potassium acetate and calcium acetate are also soluble in water at room temperature. They can be dissolved in aqueous solution and then separated by filtration.

Aqueous acetates are often used as buffers in gel electrophoresis. Because they are soluble in water, their gels may be run at lower temperatures than TAE or boric acid-based buffers, due to heat generation at a specific voltage.

In addition to its use as a buffer for gel electrophoresis, lithium acetate is useful for separating the fatty acids of the cell wall of yeast. It is also used in the pharmaceutical industry as a diuretic.

Other applications include ester interchange catalyst in polyester production, an anticorrosion agent in molding polyphenylene resins, and a catalyst in alkyd resin and Acrylic polymer production. It is also used as a raw material for lithium ion batteries. It is stable under normal temperature and pressure, but incompatible with strong oxidizing agents.
