Embodiment 1
[0013] The first step: Install a glass wool packing tower on the four-necked flask, and pass cooling water through the jacket;
[0014] The second step: 1.5mol ethyl nitrite gas is introduced from the bottom of the flask, and 1.2mol hydrazine hydrate methanol solution is added dropwise from the top of the tower;
[0015] The third step: after complete reaction, remove the reaction liquid, carry out distillation, separate methanol, obtain the sodium azide product with a synthesis rate of 85%.
