BF3-OEt2 is a liquid, whereas BF3 is a gas. Uses: As a fumigant, in ionization chambers for detection of weak neutrons, to protect molten magnesium and its alloys from oxidation, as a flux for soldering magnesium. Boron trifluoride is widely used as a catalyst for organic synthesis reactions. Boron trifluoride is a colorless gas which is formed by several reactions where a boron compound comes in contact with a fluorinating agent. Chemical Properties Boron trifluoride is a nonflammable, colorless gas with an acrid suffocating odor. Boron trifluoride: Tribluoroborane ; Formula: BF 3: Structure: Description: Boron trifluoride is a colorless gas with a pungent odor. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). Boron trifluoride has a planar geometry. Common Uses: Reagent for SEM deprotection. … They form complex of the type [BX 4]-. It is an electron deficient compound and accepts electron pairs to form coordinate covalent bonds. The information is aggregated from the data coming from REACH substance registrations provided by industry. Procedure excerpt: To a solution of the SM (0.85 g, 1.8 mmol) in DCM (10 mL) at 0 C was added BF3-OEt2 (2.33 mL, 18.4 mmol). MDL number: MFCD00071635. BF 3 + NH 3 → F 3 ← B NH 3. MeOH. 76, 77 BF 3 is an electron-deficient monomeric compound showing a trigonal planar structure with the D 3 h symmetry. This then gets converted into fluoro boric acid. . BF 3 + H 2 O → F 3 B ← OH 2. . On hydrolysis, boric acid is obtained. Dry boron trifluoride is used with mild steel, copper, copper-zinc and copper-silicon alloys, and nickel. It is technically produced by the reaction of B 2 O 3 with fluorspar and sulfuric acid: B 2 O 3 + 6HF → 2BF 3 + 3H 2 O. NACRES: NA.23 . ACGIH. It forms thick acidic fumes in moist air. Molecular Weight: 99.85 . Boron trifluoride is commonly used as a catalyst for Friedel-Crafts alkylation reactions. PubChem Substance ID: 57653917.
