Up to now, the production method of boron trifluoride ethylamine complex is to fill a quantitative monoethylamine gas into boron trifluoride diethyl ether complex (liquid), and then monoethylamine replaces diethyl ether to generate solid monoethylamine complex, and then centrifuged and dried to obtain the finished product boron trifluoride monoethylamine complex. However, the boron trifluoride monoethylamine complex prepared by this method contains a large amount of boron trifluoride ether complex impurities, and the product purity is low. The boron trifluoride ethylamine complex can be used as a curing agent for epoxy resin adhesives and as a regulator and additive for special plastics. The thermal deformation temperature of the plastic modified by the boron trifluoride monoethylamine complex is significantly increased. . In recent years, foreign R&D teams have made great breakthroughs in improving the heat resistance of plastic products. The heat resistance of plastics has reached above 300 °C. The b
