Basic information

Chemical properties: Colorless to pale yellow liquid with a fruity aroma, highly volatile, and sensitive to air. It can absorb moisture, and moisture can cause it to decompose slowly, resulting in an acidic reaction. It can dissolve certain metal salts (such as lithium chloride, cobalt chloride, zinc chloride, ferric chloride, etc.). Miscible in chloroform, ethanol, acetone and ether, slightly soluble in water. Melting point -83℃. Boiling point: 76-78℃/760mmHg. Density ρ(20) : 0.897-0.905g/mL. Refractive index n20/D1.369-1.374. Flash point: 24.8℉/-4℃.

Usage: Extractant, extracting many compounds (phosphorus, tungsten, arsenic, cobalt) from aqueous solutions; Organic solvent; It is used as a standard substance for calibrating thermometers when separating sugars. Verification of bismuth, gold, iron, mercury, oxidants and platinum; Determination of bismuth, boron, gold, iron, molybdenum, platinum, potassium and thallium; Life sciences, protein sequence analysis Environmental protection and pesticide residue analysis; Chemical synthesis Spice manufacturing.

Storage: Room temperature

Hazard Declaration: Highly flammable, irritating and anesthetic. It poses a mild hazard to water bodies.

Preventive Statement: Keep away from heat sources/hot surfaces/sparks/open flames/other ignition sources. Use explosion-proof equipment. Anti-static. Avoid inhalation. Wear protective clothing/protective gloves/protective goggles/protective masks. Fire extinguishing: dry powder, carbon dioxide, sand. Avoid prohibited foods.
