High-purity hydrogen selenide production equipment and high-purity hydrogen selenide production process based on it

Abstract

The invention provides high-purity hydrogen selenide production equipment and a high-purity hydrogen selenide production process based thereon. The high-purity hydrogen selenide production equipment comprises a reaction kettle, a dryer and a heavy-component filter, wherein the reaction kettle is provided with an inlet for feeding selenium particles, a catalyst and a solvent, is communicated with agas feeding pipe for communication to a hydrogen source and comprises a kettle body, a stirrer and a heater; the input end of the dryer is communicated with the top part of the reaction kettle; the input end of the heavy-component filter is communicated with the output end of the dryer, the heavy-component filter comprises a first tank body and a first refrigerator, and the first refrigerator isarranged on the first tank body. The high-purity hydrogen selenide production equipment and the high-purity hydrogen selenide production process provided by the invention have the beneficial effect that the problem of insufficient purity of the hydrogen selenide synthesized by reaction of high-purity hydrogen and the selenium particles due to failure in removing heavy components (such as aromaticsolvents and metal impurities) and light components (such as nitrogen, hydrogen, methane and carbon dioxide) in the prior art is solved.

Description

technical field [0001] The invention relates to the field of hydrogen selenide production, in particular to high-purity hydrogen selenide production equipment and a high-purity hydrogen selenide production process based thereon. Background technique [0002] The Chinese patent discloses a method for preparing and purifying hydrogen selenide with the application number CN200710011160.6, which is that aluminum selenide Al2Se3 reacts with water H2O to generate hydrogen selenide H2Se, and the water in the H2Se gas is removed by condensation; continue to use aluminum selenide After the particles absorb the residual moisture, the H2Se gas enters the steel cylinder to condense and liquefy; the steel cylinder containing the liquid H2Se is evacuated under the cold bath to remove the non-condensable gas impurities dissolved in the liquid; the valve of the steel cylinder is closed to obtain the purified gas directly contained in the steel cylinder Hydrogen selenide: The adsorbent that ...
