Boron trifluoride is an important Lewis acid catalyst in organic synthesis and plays a significant role in various organic reactions (such as polymerization, hydrocarbonation, alkylation, isomerization, etc.). It is inconvenient to use in gaseous form. To meet the requirements of different reactions for reactivity, according to the characteristics of boron trifluoride, it is often combined with oxygen- or nitrogen-containing compounds with chemical polarity to form stable complexes. For example, the boron trifluoride ethyl ether complex is one of the most widely used complexes in China at present. In addition, boron trifluoride can also form complexes with thioethers, alkyl halides, benzene ether, phenol, amines and many of their derivatives.
The ethyl boron trifluoride complex is commonly known as boron trifluoride diethyl ether. It is a widely used cationic polymerization catalyst, and is also a catalyst for the production of styrene rubber and polyoxymethylene. It is also the basic raw material for Chemicalbook's boron hydrogen high-energy fuel and the extraction of isotopic boron. It is commonly used as a catalyst in chemical synthesis, and is also the basic raw material for manufacturing boron hydrogen high-energy dyes and extracting isotopic boron-10.
It is used as a catalyst for synthetic rubber, resin and paint production, as well as in hydrocarbonation and condensation reactions in organic synthesis (such as styrene-butadiene rubber, polycarbonate, guanamine, synthetic resin, etc.), and is also used as a basic raw material for manufacturing borohydride high-energy fuel or extracting isotopic boron, and also as an epoxy resin curing agent, etc. It is used as a catalyst for acetylation, alkylation, polymerization, dehydration and condensation reactions in organic synthesis and as an analytical reagent. It is a basic raw material for manufacturing borohydride high-energy fuel and extracting isotopic boron, and can also be used as a curing agent for epoxy resin. It is used as an organic synthesis catalyst (catalyst for acetylation, alkylation, polymerization, dehydration and condensation reactions) and an analytical reagent. It is used as a common analytical reagent and can also be used as a catalyst for hydrocarbonation, condensation reactions, etc. in organic synthesis.
