Dibasic Esters (DBE) from factory EAST

Dibasic Ester (DBE)

Basic Information

• Appearance: Colorless transparent liquid
• Boiling point: 195–230 °C
• Density: 1.06–1.09 g/cm³
• Flash point: 99–100 °C
• Melting point: ≤-20 °C
• Odor: Tasteless or slightly sweet

Applications

1. Solvents: Used for dissolution, dilution, and separation in chemical laboratories and industrial processes. Common solvents include acetone and sulfoxide.
2. Synthetic Reagents: Catalysts in esterification reactions where acids react with alcohols to form esters. Carbonates can act as oxidants or catalysts in oxidation reactions.
3. Protective Groups in Organic Synthesis: Used to shield reactive functional groups (e.g., alcohols, amines, carboxylic acids) from side reactions, with groups like acetyl or benzoyl.
4. Polymer and Coatings Industry: Valued for weather and chemical resistance to produce waterproof coatings, corrosion-resistant films, and high-temperature polymers.
5. Other Fields: Widely applied in coatings, paints, inks, adhesives, resins, plastic plasticizers, agricultural chemicals, and oil drilling fluids.

Properties

1. Stability: Generally stable at room temperature, resistant to hydrolysis or decomposition.
2. Solubility: Low volatility, soluble in various organic solvents.
3. Flammability: Flammable, reacts with oxygen to produce toxic fumes/gases.

Preparation

Safety Precautions

1. Irritation/Corrosion: Avoid direct skin and eye contact.
2. Inhalation Risk: Use in well-ventilated areas to prevent vapor/dust inhalation.
3. Fire Hazard: Keep away from open flames and high temperatures; store in cool, dry conditions.
4. Personal Protection: Wear gloves, goggles, and protective clothing; follow safety protocols.
