Abstract

The invention provides a production method and a production device of a metal halide. The production method of the metal halide comprises the following steps: 1, mixing a halogen source and a metal element source; 2, putting the mixture into a reactor, and introducing protective gas into the reactor for 1-5 hours; 3, under the protection of a protective atmosphere, heating the mixture to 100-400 DEG C, and carrying out heat preservation for 0.5-10 hours; and 4, under the protection of a protective atmosphere, continuously heating to 500-1000 DEG C, and carrying out heat preservation for 1-50 hours to obtain the metal element halide. The production method of the metal halide is simple in step and easy to implement, no toxic or harmful substances are generated, and harm of high-corrosivity and high-toxicity halogen to human beings and the environment is avoided or reduced.

Description

technical field [0001] The invention relates to material technology, in particular to a method for producing metal halides and a production device thereof. Background technique [0002] Metal halides are widely used in the organic synthesis industry. Because they are easily hydrolyzed in water and the preparation conditions are relatively harsh, there are not many companies with production capacity at present. [0003] At present, the preparation methods of metal halides mainly adopt the following two methods: [0004] Method 1: Use hydrogen halide to interact with corresponding substances: metal halides can be obtained by hydrogen halide reacting with certain metals, metal oxides, alkalis, and salts; [0005] Method 2: Direct interaction between metal and halogen, but most anhydrous halides are easily hydrolyzed. Under normal environment or in the presence of water vapor, they are easily hydrolyzed to produce hydrogen halide and corresponding oxides. It cannot be obtained...
