Aluminum Isopropoxide
Chemical Formula:
Al(OCH(CH₃)₂)₃
CAS Number:
555-31-7
Description:
Aluminum Isopropoxide is an organoaluminium compound primarily used as a catalyst and precursor in organic synthesis. It appears as a white solid that is highly reactive with moisture and alcohols. The compound is widely employed in the production of coatings, adhesives, and pharmaceuticals, as well as in the Meerwein-Ponndorf-Verley (MPV) reduction process.
Characteristics:
- Appearance: White crystalline powder or solid
- Solubility: Soluble in organic solvents like alcohols, ethers, and hydrocarbons; reacts with water
- Melting Point: ~130°C (decomposes)
- Boiling Point: Decomposes before boiling
- Stability: Moisture-sensitive, reacts with water to form aluminium hydroxide
Applications:
- Catalyst in Organic Synthesis:
- Used in the Meerwein-Ponndorf-Verley (MPV) reduction for converting ketones and aldehydes to alcohols.
- Acts as a precursor in the synthesis of aluminium-based coatings and sol-gel materials.
- Pharmaceuticals & Fine Chemicals:
- Used in the production of various active pharmaceutical ingredients (APIs).
- Coatings & Adhesives:
- Employed in high-performance heat-resistant coatings.
- Fire Retardants:
- Used in flame-retardant formulations for plastics and polymers.
Handling & Storage:
- Store in a tightly sealed container under dry, inert conditions.
- Avoid exposure to moisture, as it reacts with water.
- Use in a well-ventilated area with protective gloves and goggles.
- Handle under an inert atmosphere (nitrogen or argon) for stability.
