PB(TMHD)2 - Introduction
Lithium 2,2, 6,6-tetramethyl -3,5-heptanedionate (LiTHD) is an organolithium compound with the following properties:
1. Appearance: White crystalline solid.
2. solubility: soluble in general organic solvents, such as ethanol, ether, etc.
3. Stability: It is relatively stable under dry conditions, but it is easy to be affected with moisture and react with moisture in the air.
4. Thermal stability: It has high thermal stability and can maintain activity at high temperatures.
The main uses of lithium 2,2, 6,6-tetramethyl -3,5-heptanedionate include the following:
1. Lithium battery electrolyte additive: As a source of lithium in the electrolyte, it improves the performance and cycle life of lithium batteries.
2. Catalyst: As a catalyst in the reaction of synthesizing organic compounds, it can promote the reaction rate.
3. Polymer additives: used to improve the performance of polymer materials, such as increasing thermal stability, improving weather resistance, etc.
