【Product Properties】

High-boiling, inert, aprotic solvent with low volatility and excellent coupling efficiency. Colorless transparent liquid with low viscosity and a high flash point (118 °C) for enhanced safety. Miscible with ethanol, acetone, and hydrocarbons; limited water solubility.

- Purity: ≥ 98.0% (GC)

- Density: 0.885 g/mL at 25 °C

- Boiling Point: 256 °C (lit.)

【Storage】Store in a cool, dry, well-ventilated area below +30 °C, away from ignition sources and oxidizing agents. Keep containers tightly closed when not in use.

【Packing】Available in standard industrial packaging: 190 kg net steel drums, IBC totes, or bulk tanker shipments. Custom packaging options available upon request.

【Application】

- Hydrometallurgy: Industrial standard solvent for selective Au(III) extraction from acidic chloride media, offering superior selectivity over base metals (e.g., Fe, Ga) with high loading capacity (≥60 g/dm³ Au).

- Coatings & Inks: Effective coalescent and coupling agent for waterborne coatings, printing inks, and cleaning formulations.

- Specialty Cleaning: Key component in grease/wax removers and low-flammability non-aqueous cleaning systems for electronic equipment.

- Electrolytes & Synthesis: Functions as a stable solvent in lithium battery electrolytes and lipase activation systems for biodiesel production.
