Shenzhen Xinxing applied for a patent for the production method of boron trifluoride to reduce production costs

Boron trifluoride is an inorganic compound with the chemical formula BF3. It is a colorless gas that is soluble in cold water, concentrated sulfuric acid and most organic solvents. It is mainly used as a catalyst in organic synthesis and is also used to make high-energy fuel for rockets. Its molecular mass is 67.81. It is a colorless, non-flammable and non-combustible gas with asphyxiating properties.

Shenzhen Xinxing Light Alloy Materials Co., Ltd. applied for a patent entitled "A method for preparing boron trifluoride", publication number CN202411105383.9, and the application date is August 2024.

The patent abstract shows that the present invention is applicable to the field of improvement of chemical product preparation technology, and provides a method for preparing boron trifluoride, including: S1, injecting H2SO4 measured by mass into the gasification tank, and starting the gasification tank for stirring after acid treatment; S2, injecting potassium fluoroborate KBF4, boron oxide B2O3 and initiator measured by mass into the gasification tank; S3, when the gasification tank is gradually heated to the set temperature and preset pressure, the mixture added to the gasification tank starts to react to generate boron trifluoride BF3 gas for external output. The preparation method reduces the reaction temperature, shortens the reaction time, improves the reaction efficiency, reduces the production cost, and reduces the consumption of raw materials by adding an initiator to catalyze the reaction; after acid treatment, the added mixture is fully mixed by stirring.
