Detailed Manufacturing Process of 19372 44 2

The production of high-purity Calcium(II) Acetylacetonate is a meticulous chemical synthesis process requiring precise control over reaction parameters, purification techniques, and quality assurance. The typical manufacturing flow ensures a product that meets rigorous industrial standards, such as those specified by ISO 9001 for quality management and specific ASTM or internal testing protocols for product performance.

1. 1. Raw Material Sourcing and Preparation:

   The primary raw materials include a high-purity calcium source (e.g., calcium oxide, calcium hydroxide, or calcium carbonate) and acetylacetone (2,4-pentanedione). Solvents, typically water or organic solvents like ethanol, are also crucial. All raw materials undergo stringent quality checks to ensure minimal impurities, which is critical for the final product's purity and performance.

2. 2. Synthesis/Chelation Reaction:

   The core of the process involves the chelation reaction where the calcium source reacts with acetylacetone. This is typically performed in a reaction vessel under controlled temperature and pH. The reaction mechanism involves the deprotonation of acetylacetone to form the acetylacetonate anion, which then coordinates with the calcium(II) cation.

   Schematic Steps:

   • Step A: Dissolution of calcium source in solvent.
   • Step B: Addition of acetylacetone.
   • Step C: Controlled stirring and heating to facilitate chelation.
   • Step D: pH adjustment to optimize yield and purity, often maintaining slightly alkaline conditions.

3. 3. Purification and Isolation:

   Following the reaction, the crude product contains unreacted materials, by-products, and solvent. Purification steps are critical to achieve the desired high purity. These typically include:

   • Filtration: To separate the solid product from the liquid phase.
   • Washing: Multiple washes with appropriate solvents (e.g., water, ethanol) to remove soluble impurities.
   • Recrystallization (optional): For ultra-high purity grades, the product may be dissolved and recrystallized to further enhance purity and control crystal structure.

4. 4. Drying and Grinding:

   The purified solid product is then subjected to controlled drying to remove residual solvents and moisture. This is often done in vacuum ovens or rotary dryers at specific temperatures to prevent thermal degradation. After drying, the product may be milled or ground to achieve a desired particle size distribution, which is crucial for uniform dispersion and performance in applications like polymer additives or thin-film precursors.

5. 5. Quality Control and Packaging:

   Before packaging, every batch of calcium acetylacetonate undergoes a comprehensive suite of analytical tests. These include purity analysis (HPLC, GC-MS), elemental analysis (ICP-OES), thermal analysis (TGA, DSC), moisture content (Karl Fischer), and particle size distribution. Testing standards adhere to internal specifications, customer requirements, and international norms like ISO or ASTM where applicable. The product is then carefully packaged in moisture-resistant container111s, often with inert gas purging, to maintain its integrity during storage and transport. This stringent process ensures a consistent, high-quality product with a predictable service life in its intended application.
