Description

technical field [0001] The invention relates to the technical field of preparation of boron trifluoride complexes, in particular to a continuous synthesis method and reaction device for boron trifluoride complexes. Background technique [0002] Boron trifluoride is an important chemical raw material, not only the main raw material for the preparation of boron halide, boron simple substance, borane, sodium borohydride, etc.; it can also be used as a catalyst for organic reactions, such as esterification, alkylation, polymerization , Isomerization, sulfonation, nitration, etc. However, boron trifluoride is a gas, and it is extremely inconvenient to use. Most of them are not directly used, but complexes of boron trifluoride are used. [0003] Among them, boron trifluoride ether complexes are mainly used as catalysts for acetylation, alkylation, polymerization, dehydration and condensation reactions, as epoxy resin curing agents, or as boron hydrogen high-energy fuels and extra...
