Examples
Embodiment 1
[0019] Add 200g of isopropanol, 20g of aluminum chips and 2g of aluminum isopropoxide into the reaction flask, and heat until the isopropanol refluxes. After the reaction between isopropanol and aluminum chips (which can be in the form of flakes, strips, powders, etc.), the number of bubbles increases, the liquid level begins to rise, and the heating is stopped. After about 20 minutes, the reaction reached a violent state, a large number of bubbles were generated, and the liquid level boiled and rose. When 0.22 g of acetone was added, the reaction rate decreased rapidly, and the reaction basically stopped after 2 minutes. After reheating to reflux of isopropanol for about 30 minutes, the reaction was restarted.
Embodiment 2
[0021] Add 200g of isopropanol, 20g of aluminum chips and 0.5g of anhydrous aluminum chloride into the reaction flask, and heat to reflux of isopropanol. After the isopropanol starts to react with the aluminum chips, turn off the heat. After about 15 minutes, the reaction reached a violent state, a large number of bubbles were generated, and the liquid level boiled and rose. When 0.22 g of acetone was added, the reaction rate decreased rapidly, the bubbles decreased rapidly, and the liquid level dropped. After 2 minutes, the reaction basically stopped. After reheating to reflux of isopropanol for about 30 minutes, the reaction was restarted.
Embodiment 3
[0023] Add 200g of isopropanol, 20g of aluminum chips and 2g of aluminum isopropoxide into the reaction flask, and heat until the isopropanol refluxes. After the isopropanol starts to react with the aluminum chips, turn off the heat. After about 20 minutes, the reaction reached a violent state. After adding 1.11 g of acetone, the reaction rate decreased rapidly, and the reaction basically stopped after 2 minutes. After reheating to reflux of isopropanol for about 6 hours, the reaction was restarted.
