Steps:

1-8 Example 3

Preparation method of allyltrimethylsilane, the magnesium foil (25 g, 1.028 moles), aluminum foil (6.9 g, 0.257 moles) and solvent divinyl ether 300 g added to the reaction bottle, to the reaction bottle dropwise added chloropropylene (89.3 g, 1.168 moles) and trimethylchlorosilane (152.2 g, 1.401 moles) of the mixed solution, the control temperature during the drop addition process is 50 °C±5 °C, after the end of the drop heating to the reflux state to continue the reaction for 5 hours, After the end of the reaction, the reaction liquid was filtered, and the filtrate was separated and purified by atmospheric distillation to obtain 113 grams of allyltrimethylsilane, which was analyzed by gas chromatography with a content of 99.3%, a yield of 84%, a moisture of 50 ppm, a chloride 1.2 ppm, a bromine 1.3 pm, an iodine ion of 1.2 ppm, and a chromaticity of 10 Hazl.
