Disilane reaction kettle

Abstract

The invention relates to the technical field of synthetic reaction equipment, and discloses a disilane reaction kettle, which comprises a kettle body, a feeding funnel is fixedly mounted on one side of the top of the kettle body, a movable cover is fixedly mounted on the top of one side of the feeding funnel, and one side of the movable cover is in threaded connection with the top of the other side of the feeding funnel through a fixing bolt, the middle of the top end of the kettle body is movably sleeved with a rotating shaft, stirring blades are fixedly installed at the bottom of the side face of the rotating shaft, the top end of the rotating shaft fixedly sleeves an output shaft of a motor, and the outside of the motor is fixedly connected with the top of the kettle body through a fixing frame. According to the disilane reaction kettle, impurities in disilane gas can be absorbed and filtered through a filtering device in the disilane gas collecting process, the problem that the disilane gas is influenced by volatilization of hydrogen chloride is avoided, the purity of the disilane gas is improved, the disilane gas can be refrigerated at a low temperature through a collecting box, and the safety in the disilane gas storage process is ensured.

Description

technical field [0001] The invention relates to the technical field of synthesis reaction equipment, in particular to a disilane reaction kettle. Background technique [0002] Disilane is an inorganic compound, which is a colorless, transparent, toxic gas with an unpleasant and irritating odor at normal temperature and pressure. It has similar chemical properties to silane and is more unstable than silane. It can be slowly decomposed into silane and hydrogen at room temperature. , Disilane is soluble in carbon disulfide, ethyl alcohol, benzene and ethyl silicic acid, it corrodes rubber, butter, lubricating oil and lead, etc., but it does not corrode most metals. [0003] There is a disilane reactor with the publication number of 201620823605.5. Although this technical solution improves the slagging speed, saves the reaction time, has the advantages of low production cost, low equipment corrosion, and continuous and stable production, but in B In the process of silane synthe...

Problems solved by technology

[0006] Aiming at the deficiencies of the above-mentioned comparative examples, the present invention provides a disilane reaction kettle, which is capable of uniformly mixing the reactants, speeding up the reaction, improving the synthesis efficiency of disilane, and simultaneously being able to remove excess hydrogen chloride during the reaction. Collection and recycling avoids the waste of hydrogen chloride, reduces the cost of production, and can filter the synthesized disilane gas, which improves the purity of disilane gas and solves the problem of existing disilane synthesis. During the process, because hydrogen chloride and magnesium silicide cannot be mixed uniformly, the two cannot fully react, resulting in slow reaction speed and low synthesis efficiency. Hydrogen chloride causes waste, increases the cost of production, and hydrogen chloride is volatile and easily doped in the synthesized disilane gas, which leads to the problem of low purity of disilane
