| overview | boron trifluoride acetonitrile is a colorless or light yellow transparent liquid with a relative density of 0.9g/cm3, high solubility, soluble in water, miscible in various organic solvents such as alcohol and ether, and is mainly used as a catalyst for organic reactions. it is an important raw material for cephalosporin antibiotics to prepare boron halide, elemental boron, borane, sodium borohydride and other borides, it is the basic raw material for the manufacture of boron-hydrogen high-energy fuels and the extraction of isotopes. It can also be used as a curing agent for epoxy resins. It is generally prepared by the reaction of fuming sulfuric acid, boric acid, hydrogen fluoride and acetonitrile. |
| application | boron trifluoride complex is a highly active catalyst that can be used in a variety of organic synthesis reactions, especially in cephalosporins In the synthesis process of antibacterial drugs, the introduction of boron trifluoride complex shortens the reaction time of the original product and greatly improves the yield of the original product. |
| preparation | the current preparation method of boron trifluoride acetonitrile complex is as follows: 20% fuming sulfuric acid, boron anhydride and fluorite are reacted at a mass ratio of 9:1:3 at 130 ℃ to generate boron trifluoride gas, which is then introduced into acetonitrile for complexation, and the finished product is acetonitrile solution of boron trifluoride acetonitrile complex. |
| Uses | Mainly used as a catalyst for organic reactions, it is an important raw material for the preparation of boron halides, elemental boron, borane, sodium borohydride and other borides. It is the basic raw material for the manufacture of boron-hydrogen high-energy fuel and the extraction of isotopes. It can also be used as a curing agent for epoxy resins. As a special catalyst for the production of antibiotics in medicine |
