CAS 109-63-7 corresponds to boron trifluoride ethyl ether complex, which is a strong Lewis acid catalyst and epoxy resin curing agent. It is a colorless to light yellow smoky liquid at room temperature, which undergoes severe hydrolysis in water and releases corrosive gases.

Core physical and chemical parameters
-Chemical formula: C ₄ H ₁₀ BF ∝ O (or written as BF ∝· O (C ₂ H ₅) ₂)
-Molecular weight: 141.93
-Appearance: Colorless to light yellow transparent liquid, with a pungent ether odor, smoking in humid air
-Melting point: -60.4 ℃; Boiling point: 125-129 ℃; Density: Approximately 1.15 g/cm ³ (25 ℃)
-Flash point: -17 ℃ (flammable); Refractive index:~1.345 (20 ℃)
-Solubility: soluble in organic solvents such as ethanol and ether, and violently decomposes when in contact with water

main purpose
1. Organic synthesis catalysts: widely used in acetylation, alkylation, polymerization, condensation, and dehydration reactions (such as Friedel Crafts reactions)
2. Industrial applications: epoxy resin curing agent, synthetic rubber/resin additives, boron hydrogen high-energy fuel raw materials
3. Other fields: analytical reagents, isotope boron-10 extraction, electrochemical polymeric electrolytes

Safety and Storage
-Hazard: Highly corrosive, flammable, toxic; Exposure to water or moisture releases hydrogen fluoride (HF) and flammable hydrogen gas
-Protection requirements: Wear corrosion-resistant gloves, goggles, and respiratory protection, keep away from sources of fire and water
-Storage conditions: Sealed and away from light, dry and ventilated place, recommended temperature of 2-8 ℃, strictly prohibited from contact with water
