Beilstein/REAXYS Number: 3611499 . MDL number: MFCD00071635. Boron trifluoride diethyl etherate (BF3-OEt2) is a convenient, easy to handle source of boron trifluoride (BF3). MeOH. NACRES: NA.23 . Molecular Weight: 99.85 . 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). This then gets converted into fluoro boric acid. Dry boron trifluoride is used with mild steel, copper, copper-zinc and copper-silicon alloys, and nickel. Boron trifluoride is widely used as a catalyst for organic synthesis reactions. BF 3 + H 2 O → F 3 B ← OH 2. Uses of BF3 (Boron Trifluoride) BF3 (Boron Trifluoride) has many uses in various industries. Chemical Properties Boron trifluoride is a nonflammable, colorless gas with an acrid suffocating odor. Boron trifluoride is a colorless gas which is formed by several reactions where a boron compound comes in contact with a fluorinating agent. 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 also used to protect molten magnesium and its alloys from oxidation. Boron trifluoride is commonly used as a catalyst for Friedel-Crafts alkylation reactions. The reaction was allowed to warm to RT and stir for 2 h. . Boron trifluoride/ Preparation/Physical properties/BF3 as Lewis acid/Hydrolysis of Boron trifluoride /Uses/ Class 12/ p block elements - I ( Part - 17) It forms thick acidic fumes in moist air. On hydrolysis, boric acid is obtained. … It is used as adhesives and sealant chemicals, adsorbents and absorbents, fuels and fuel additives, oxidizing/reducing agents, binding agent for industrial manufacturing, plastics industry, drug production, etc. It is an electron deficient compound and accepts electron pairs to form coordinate covalent bonds. They form complex of the type [BX 4]-. Boron trifluoride has a planar geometry.
