Lithium chloride is an inorganic substance with the molecular formula LiCl and a molecular weight of 42.39. It is a white crystal with deliquescence. Salty in taste, easily soluble in water, organic solvents such as ethanol, acet.one, pyridine, etc. Belongs to the low toxicity category, but has strong irritant and corrosive effects on the eyes and mucous membranes.

pysical property

Lithium chloride is a white crystal that is easily soluble in water, with a standard solubility of 67g/100ml of water. It is also easily soluble in organic solvents such as ethanol, acet.one, pyridine, but difficult to dissolve in ethylamine. Therefore, when preparing alkyl lithium, if chlorohalogenated hydrocarbons are used in ethylamine, lithium chloride can precipitate and free alkyl lithium reagents can be obtained (lithium bromide and lithium iodide form adducts with alkyl lithium and act as stabilizers). [1] The melting point of lithium chloride is 605 ℃, the boiling point is 1350 ℃, and the lattice energy is 853 kJ/mol.

chemical property

The aqueous solution is neutral or slightly alkaline. Electrolysis of anhydrous lithium chloride can generate metals, lithium, and chlorine. [2] Electrolytic anhydrous lithium chloride pyridine solution can also deposit metal lithium. [3]

Lithium chloride can form various hydrates, and the phase diagram of LiCl-H2O clearly shows that its hydrates include several types such as LiCl · H2O, LiCl · 2H2O, LiCl · 3H2O, LiCl · 5H2O, etc. The number of crystalline water depends on the temperature of crystallization, and the lower the temperature, the higher the degree of hydration.

Li can form coordination ions with ammonia [Li (NH3) 4], so the solubility of ammonia gas in lithium chloride solution is much higher than in water. Like other ion chlorides, lithium chloride can also provide chloride and lithium ions in aqueous solutions, and precipitate insoluble chlorides or lithium salts with certain other ions, such as silver chloride:

LiCl+AgNO3 → AgCl ↓+LiNO3

Solubility

Lithium chloride has a sodium chloride type structure, and its chemical bonds are not typical ionic bonds. Therefore, it can dissolve in many organic solvents and form different adducts with ethanol, methanol, and amines. This property can be used to separate lithium chloride from alkali metal chlorides.

Due to the smaller ion radius and higher hydration energy of lithium, the solubility of lithium chloride is much higher than other similar chlorides (83g/100mL, 20 ℃). Its aqueous solution is alkaline.
