Lanthanum Chloride, Lanthanum Trichloride, 10099-58-8

LANTHANUM CHLORIDE (ANHYDROUS) 

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Lanthanum chloride (anhydrous) is the chloride salt of lanthanum in its anhydrous form. Lanthanum ions (La³⁺) and chloride ions (Cl⁻) are present in a 1:3 ratio. Unlike the heptahydrate form, this compound contains no water of crystallization. It is highly hygroscopic and readily absorbs moisture from the air to form the hydrated salt.

20. CRITICAL NOTICES AND BEST PRACTICES

CRITICAL NOTICES:

1. High Hygroscopicity: Anhydrous lanthanum chloride is highly hygroscopic and readily absorbs moisture from the air to form the hydrated salt. Must be stored in air-tight, moisture-proof containers.

2. Storage Conditions: Must be stored in a dry environment. Exposure to moisture will result in hydration and product degradation.

3. Handling: Should be handled in low-humidity environments. Containers must be sealed immediately after use.

4. Incompatibility: Reacts with strong oxidizing agents, strong bases, and reactive metals.

5. Thermal Stability: Stable up to melting point (~860°C). Decomposes at higher temperatures.

6. Regulatory Compliance: REACH registration required for EU; KKDIK compliance required for Turkey.

BEST PRACTICE RECOMMENDATIONS:

Storage:

• Store in a cool, dry, well-ventilated area

• Use air-tight, moisture-proof containers

• Store with desiccant (silica gel)

• Keep away from acids and strong oxidizers

• Store at room temperature (15-25°C)

Handling:

• Use in well-ventilated areas

• Use dust mask, protective goggles, and gloves

• Avoid dust formation

• Wash hands after handling

• Immediately reseal container after use

Waste Management:

• Dispose in accordance with local regulations

• Do not discharge into water bodies

• Consider rare earth recovery for large quantities
