Products Description of Boron Trifluoride Diethyl Etherate CAS#109-63-7

Boron trifluoride is an important Lewis acid catalyst in organic synthesis and plays an important role in organic reactions (such as polymerization, hydrocarbonization, alkylation, isomerization, etc.). It is inconvenient to use trifluoride when it is in gaseous state. In order to adapt to the activity requirements of different reactions, according to the characteristics of trifluoride, it is often combined with polar oxygen- or nitrogen-containing compounds to convert it into a complex with strong stability. For example, boron trifluoride etherate complex is a complex that is widely used in China. In addition, boron trifluoride can also form complexes with thioethers, cyclones, anisole, phenol, amines and many of their derivatives.
