Lithium tartrate (酒石酸锂) is a chemical compound with the formula $mathrm{Li_2C_4H_4O_6}$. It is the lithium salt of tartaric acid, characterized by its white crystalline structure and solubility in water. The compound plays a significant role in industrial and scientific applications due to its unique physicochemical properties.
Chemical Structure
Lithium tartrate consists of two lithium cations ($mathrm{Li^+}$) bonded to a tartrate anion ($mathrm{C_4H_4O_6^{2-}}$), forming a stable ionic lattice. Its synthesis typically involves neutralizing tartaric acid with lithium carbonate or hydroxide.
Industrial Applications
It is widely used as a chiral resolving agent in asymmetric synthesis and pharmaceutical manufacturing. Additionally, lithium tartrate serves as a precursor in lithium-ion battery electrolytes and specialized ceramics.
Laboratory Use
In analytical chemistry, it functions as a buffering agent and chelator in electrochemical studies. Its optical activity also makes it valuable in polarimetry for measuring enantiomeric excess.
Safety and Handling
The compound is classified as an irritant. Proper handling requires protective equipment (gloves, goggles) and adequate ventilation. First-aid measures for exposure include rinsing with water and seeking medical attention.
