LANTHANUM ACETATE 

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Lanthanum acetate is the acetate salt of lanthanum. Lanthanum ions (La³⁺) and acetate ions (CH₃COO⁻) are present in a 1:3 ratio. The compound is an organic salt that is soluble in water and alcohol, with low to moderate hygroscopicity compared to other lanthanum salts such as chloride and nitrate.

19. CRITICAL NOTICES AND BEST PRACTICES

CRITICAL NOTICES:

1. Low to Moderate Hygroscopicity: Lanthanum acetate has lower hygroscopicity compared to chloride and nitrate salts, making it easier to handle and store.

2. Thermal Stability: Stable up to 500°C; decomposes at higher temperatures to lanthanum oxide.

3. Organic Nature: Acetate salt with low toxicity and good solubility in organic solvents.

4. Skin and Eye Irritation: Causes skin and eye irritation. Use appropriate personal protective equipment.

5. Inhalation Hazard: Dust may cause respiratory irritation. Use in well-ventilated areas.

6. Acetic Acid Odor: May have slight acetic acid odor, especially when exposed to moisture.

7. Suitable for Organic Systems: More suitable for organic applications compared to inorganic salts.

BEST PRACTICE RECOMMENDATIONS:

Storage:

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

• Use moisture-proof containers

• Store at room temperature (15-25°C)

• Keep away from strong acids and strong bases

Handling:

• Use in well-ventilated areas

• Use dust mask, protective goggles, and gloves

• Avoid dust formation

• Wash hands after handling

• 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
