Sodium azide (NaN3) and hydrazine sulfate (N2H4 ·H2SO4) were purchased from Sigma-Aldrich (St. Louis, MO, USA). Hydrazine monohydrate (N2H4·H2O) was obtained from Tokyo Chemical Industry Co. (Tokyo, Japan) and n-butanol was purchased from Daejung (Seoul, Korea). They were used without further purification. Hydrazinium azide (HA) was obtained by the reaction of sodium azide and hydrazine.

Preparation of ammonium azide
Preparation of ammonium azideAmmonium azide is prepared by subliming an intimate mixture of 2 g of dry sodium azide and 2.5 g of dry ammonium nitrate at 190° C in a simple sublimation apparatus by passing dry air or nitrogen for 30-40 min. The yield of ammonium azide is over 93%. J. Am. Chem. Soc., 1934, 56 (11), pp 2384–2384
위 실험은 에탄올에 페놀프탈레인 용액을 넣고 Sodium 을 넣고 반응 시키는 것입니다. Sodium 이 에탄올과 반응하면서 수소 기체가 발생하고 페놀프탈레인 색이 바뀌는 것을 봤을 때 basic 한 형태 (OH-)가 생긴것으로 보입니다. 2CH3CH2OH + 2Na -> 2CH3CH2ONa + H2 Ethoxide 형태가 Strongly basic 하다고 하네요. (https://www.chemguide.co.uk/organicprops/alcohols/sodium.html)
