Product Overview
Boron trifluoride etherate (CAS 109-63-7), also known as Boron trifluoride diethyl etherate, is a classic Lewis acid complex formed by boron trifluoride and diethyl ether. It appears as colorless to pale yellow transparent liquid, which fumes heavily in moist air. With strong Lewis acidity, high catalytic activity and excellent solubility in organic solvents, it is one of the most widely used acid catalysts in organic synthesis and industrial production. Manufactured via advanced complexation and purification processes, this product features stable BF3 content, low impurities and consistent batch quality. For legitimate industrial synthesis, formulation and scientific research only.
Product Features
- High Purity & Stable Content: BF3 content 47.0%–48.5% (industrial grade), ≥49.0% (pharma/electronic grade), with strict control of moisture and related impurities.
- Strong Lewis Acidity: Excellent catalytic performance for various organic reactions, with high activity and good selectivity.
- Good Solubility: Miscible with most organic solvents such as ether, alcohol, dichloromethane and aromatic hydrocarbons, convenient for reaction formulation.
- Mature Industrial Application: Widely verified in large-scale industrial production, with stable and reliable performance.
- Strict Quality Control: Each batch is fully tested; standard COA, GC and inspection reports are available.
Physical & Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow transparent liquid
- Odor: Pungent, irritating ether-like odor
- Melting Point: -60.4 °C
- Boiling Point: 126 – 129 °C (760 mmHg)
- Density: 1.15 g/mL (20 °C)

- Reactivity: Undergoes typical Lewis acid catalyzed reactions, including alkylation, acetylation, esterification, polymerization and condensation.
- Thermal Stability: Gradually decomposes above 130 °C, releasing toxic boron trifluoride and ether fumes.
- Incompatibility: Avoid contact with water, strong bases, strong oxidants, alcohols and reactive metals.
Applications
- Organic Synthesis Industry: Core Lewis acid catalyst for alkylation, acetylation, esterification, isomerization, condensation and cyclization reactions in fine chemical and pharmaceutical synthesis.
- Polymer Industry: Catalyst for the production of butadiene rubber, polyoxymethylene, coumarone resin and epoxy resin curing agent.
- Pharmaceutical & Fragrance Industry: Key catalyst for the synthesis of vitamin A, vitamin E, steroid drugs and various aroma chemicals.
- Specialty Chemicals: Raw material for the preparation of boron hydride fuels, boron isotope separation and other high-value boron compounds.
- Laboratory Research: Standard Lewis acid reagent for organic chemistry, catalytic chemistry and material science experiments.
Usage Restriction: For industrial synthesis and scientific research use only. Strictly forbidden for illegal processing and improper application.
Storage & Transportation Instructions
Storage Conditions: Store in a cool, dry, well-ventilated and fire-proof warehouse. Keep container tightly sealed with a nitrogen blanket to prevent moisture absorption and decomposition.
