Product Overview
Lanthanum(III) acetate sesquihydrate from REacton™ delivers 99.99% rare earth oxide (REO) purity, ensuring minimal impurities for critical applications. This crystalline powder exhibits excellent solubility in water and polar solvents, making it ideal for homogeneous reactions and solution-based processes. The sesquihydrate form provides stable hydration without compromising reactivity, while the acetate ligand offers compatibility with a wide range of organic and inorganic systems. Its high lanthanum content (adjusted for REO basis) guarantees consistent stoichiometry in formulations, reducing batch-to-batch variability. The product undergoes rigorous quality control to meet REacton™ standards, with trace metal analysis confirming low levels of common contaminants like iron, calcium, and heavy metals. Its non-hygroscopic nature simplifies handling and storage compared to other lanthanum salts, while the acetate counterion avoids chloride or nitrate-related corrosion issues. The material’s uniform particle size distribution ensures reproducible dissolution kinetics, critical for time-sensitive reactions. As a rare earth acetate, it serves as a versatile precursor for lanthanum oxide coatings, doped materials, and coordination complexes where purity directly impacts performance.
FAQs
1. What is the difference between 99.9% and 99.99% REO purity in lanthanum acetate?
The 99.99% REO specification indicates tighter control over trace impurities, particularly other rare earth elements and transition metals. This higher purity is essential for applications where even minor contaminants could affect catalytic activity or material properties. The 99.9% grade may contain up to 10x more impurities by weight, which can accumulate in sensitive systems.
2. Can this product be used directly in aqueous solutions without pH adjustment?
Lanthanum(III) acetate forms slightly acidic solutions (pH ~5-6) when dissolved in water due to partial hydrolysis. For most applications, no pH adjustment is required, but for pH-sensitive reactions, we recommend monitoring and adjusting with dilute ammonia or acetic acid as needed. The acetate buffer system helps stabilize the pH within a narrow range.
3. What are the storage recommendations to prevent moisture absorption?
While this sesquihydrate form is less hygroscopic than anhydrous lanthanum salts, we recommend storing the unopened container in a cool, dry place (15-25°C) with relative humidity below 60%. After opening, reseal the container tightly and consider using desiccant packs for long-term storage. Avoid refrigeration as temperature fluctuations can cause condensation inside the container.
4. Is this product compatible with common organic solvents like ethanol or acetone?
The solubility in organic solvents is limited compared to water, but the product shows moderate solubility in lower alcohols (ethanol, methanol) and polar aprotic solvents like DMSO. It is virtually insoluble in non-polar solvents like acetone, hexane, or toluene. For organic-phase reactions, we recommend preparing a concentrated aqueous solution first, then transferring to the organic system if compatible.
5. How does the acetate ligand affect the product’s thermal decomposition profile?
The acetate groups begin decomposing around 200-250°C, releasing acetic acid and forming lanthanum oxide or oxycarbonate intermediates. Complete conversion to La2O3 typically requires temperatures above 600°C. This decomposition pathway is cleaner than nitrate or chloride precursors, producing fewer corrosive byproducts during calcination processes.
