Is lithium acetate, the lithium salt of acetic acid, with molecular formula CH3COOLi.

Production and representation

Lithium acetate can be prepared by salt-forming reaction of lithium hydroxide and acetic acid.

Similarly, the synthesis of lithium carbonate and acetic acid is possible with evolution of carbon dioxide.

Properties

In the commercial lithium is usually supplied as a white dihydrate with the formula CH3COOLi · 2 H2O. The dihydrate crystallizes in the orthorhombic crystal system, space group CMM2 with lattice constants a = 686 pm, b = 1149 pm and c = 659 pm. The anhydrate crystallizes in the triclinic crystal system in the space group with the lattice constants a = 929 pm, b = 1213 pm and c = 676 pm and α = 101 °, β = 100 ° and γ = 105 °.

Use

Lithium acetate is used as the buffering agent in the gel electrophoresis of DNA and RNA, in the transformation of yeast cells by the lithium acetate method, and in the lithium therapy. Furthermore, it acts as a catalyst in the polyester production, as a corrosion inhibitor in Polyphenylsulfidharzen and as catalyst in the production of alkyd resins and acrylic polymers.
