Embodiment 1
[0034] In a reactor full of high-purity nitrogen, put 580g of mixed particles of gallium and magnesium (wherein Ga:Mg=30%:70% (weight)), add 2100g of anhydrous ether as a solvent, heat to reflux, and stir 1061g methyl iodide (CH 3 1), after adding methyl iodide, continue to reflux for 3 hours to obtain the mixture; then place the mixture to room temperature and filter to remove magnesium iodide therein, and the filtrate is distilled off under reduced pressure at 1000Pa to remove excess solvent, and then The residue is placed in an ice-water bath under reduced pressure (1mmHg pressure) to precipitate a complex (substance A) formed by trimethylgallium and an organic solvent, and then heat the complex (substance A) (at a temperature of 70°C) Trimethylgallium (substance B) was decomposed in 4 hours; the obtained trimethylgallium (substance B) was placed in a precision vacuum distillation device, and the reflux ratio was 1, the operating pressure at the top of the tower was 100Pa, ...
Embodiment 2
[0037] In a reactor full of high-purity nitrogen, put 580g of mixed particles of gallium and magnesium (wherein Ga:Mg=50%:50% (weight)), add 2954g of anhydrous ether as a solvent, heat to reflux, and stir 2050g methyl iodide (CH 31), after adding methyl iodide, continue to reflux for 4 hours to obtain the mixture; then place the mixture to room temperature and filter to remove the magnesium iodide therein, and the filtrate is distilled off under reduced pressure at 1000Pa to remove excess solvent, and then The residue is placed in an ice-water bath under reduced pressure (pressure 50mmHg) to precipitate a complex (substance A) formed by trimethylgallium and an organic solvent, and then heat the complex (substance A) (temperature 100°C) Trimethylgallium (substance B) was decomposed in 3 hours; the obtained trimethylgallium (substance B) was placed in a precision vacuum distillation device, the reflux ratio was 1, the operating pressure at the top of the tower was 100Pa, and the...
Embodiment 3
[0040] In a reaction kettle full of high-purity nitrogen, put 580g of mixed particles of gallium and magnesium (wherein Ga:Mg=70%:30% (weight)), add 2100g of anhydrous tetrahydrofuran as a solvent, heat to reflux, and stir 4963g methyl iodide (CH 3 1), after adding methyl iodide, continue to reflux for 5 hours to obtain the mixture; then place the mixture to room temperature and filter to remove the magnesium iodide therein, and the filtrate is distilled off under reduced pressure at 1000Pa to remove excess solvent, and then the distillate The residue is placed in an ice-water bath under reduced pressure (100mmHg pressure) to precipitate a complex (substance A) formed by trimethylgallium and an organic solvent, and then heat the complex (substance A) (temperature 140°C) Trimethylgallium (substance B) was decomposed in 4 hours; the obtained trimethylgallium (substance B) was placed in a precision vacuum distillation device, and the reflux ratio was 1, the operating pressure at ...
