Abstract

The invention discloses a technique for preparing phosphine by performing a hydrolysis reaction on aluminium phosphide. Particularly, the technique adopts the following technical scheme that: a gas inlet pipe is connected with and installed at the lower end of an integrated reaction chamber; the reaction chamber is connected with a conduit through one end of a gas outlet pipe; the conduit is connected with a fumigant transfer pipe; a fan is connected with and installed on the lower part of the fumigant transfer pipe; the fan is connected with the reaction chamber through the other end of the gas outlet pipe; the upper part of the reaction chamber is connected with a cartridge case through a slim tube; a piston is connected to and installed in the cartridge case; a driving plate is connected with and installed at the upper end of the piston; and a gas distributing plate and a stirrer are connected to and installed in the reaction chamber. The technique has reasonable design, is convenient for use and is an ideal process technique for preparing the phosphine.

Description

Technical field [0001] The invention relates to a technique for chemically producing phosphine, in particular to a technique for preparing phosphine by hydrolyzing aluminum phosphide, which is suitable for chemical synthesis of phosphine. Background technique [0002] At present, phosphine has important uses in many industrial fields such as semiconductor industry, chemical industry, grain storage industry and metallurgical industry, but the production process is complicated, the cost is high, and the product quality is poor. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a technology for preparing phosphine by hydrolyzing aluminum phosphide. The technology is not only reasonable in process and simple in preparation, but also has easy-to-obtain raw materials, high product yield, and the purity of the produced phosphine reaches 5N (99.999%), and solves the problem of environme...
