Overview
Diethylacetamide (DEAC) is an organic solvent and intermediate widely used in pharmaceutical and agrochemical industries. Its balanced polarity and high boiling point make it suitable for reactions requiring stable solvation. DEAC is synthesized via the reaction of diethylamine with acetic anhydride. It is valued for its ability to dissolve both hydrophilic and hydrophobic compounds, bridging gaps in formulation chemistry.
Physical and Chemical Properties
DEAC is a colorless to pale yellow liquid with a mild amine-like odor. It has a density of 0.92 g/cm³ and boils at 186-188°C, making it useful for high-temperature processes. Its miscibility with water and organic solvents like ethanol or acetone enhances versatility. The compound is stable under normal conditions but may decompose at extreme temperatures, releasing toxic fumes.
Main Applications
In pharmaceuticals, DEAC serves as a solvent for APIs (Active Pharmaceutical Ingredients) and in crystallization processes. It is also employed in pesticide formulations to improve active ingredient dispersion. Industrially, DEAC aids in polymer processing and specialty coatings. Its solvation properties are leveraged in lithium-ion battery electrolytes and adhesives.
Safety and Storage
DEAC is classified as an irritant (skin/eye) and requires PPE such as gloves and goggles. Avoid inhalation and ensure workplace ventilation meets OSHA standards. Store in sealed containers away from oxidizers and acids. Fire hazards are moderate; use dry chemical or CO2 extinguishers for emergencies. Spills should be contained with inert absorbents.
B2B Procurement Guide
Buyers should prioritize suppliers with ISO 9001 certification to ensure consistent quality. Request COA (Certificate of Analysis) for purity verification, typically ≥98% for industrial use. Bulk shipments require UN-certified packaging and hazardous material transport documentation. Spot prices fluctuate with raw material (acetic anhydride) costs; long-term contracts may offer stability.
