Preparation method of di(diethylamino)silane

The invention provides a preparation method of di(diethylamino)silane. The method comprises the following steps: step 1, adding an alkane CnH(2n+2) (n>=5) solution of n-butyllithium into a reactor protected by inert atmosphere, dropwise adding diethylamine for a reaction while performing stirring, maintaining the temperature of the reaction system in a range from -60 DEG C to -30 DEG C, and performing stirring for reaction for 10-15 h; step 2, pumping dichlorosilane in at a temperature in a range from -60 DEG C to -30 DEG C, performing stirring for reaction for 15-20 h while maintaining the temperature in a range from -60 DEG C to -30 DEG C, increasing the temperature to a room temperature, and evaporating alkane CnH(2n+2) (n>=5) under a normal pressure; and step 3, performing vacuum distillation to make a coarse di(diethylamino)silane product out. The coarse di(diethylamino)silane product is subjected to vacuum distillation to obtain di(diethylamino)silane with high purity. The preparation method has the beneficial effects that the selected reagents are free of toxicity, thereby ensuring safety of operators; the reaction process is relatively mild and has no potential safety hazard; and the reaction efficiency is very high.
