용도
용도
Sodium Amide is widely used in organic chemical synthesis as a strong base in reactions such as in the preparation of phenylacetylene from 1,2-dibromophenylethane. Also used in the synthesis of 2,6-diamination of substituted pyridines as initiator of heterogeneous chichibabin reaction.
일반 설명
Odorless colorless solid. Denser than water.
제조 및 합성 방법
제조 방법
Sodium amide is prepared by passing dry ammonia gas over sodium metal at 350°C: 2Na + 2NH3 → 2NaNH2 + H2Also, it may be prepared by reacting sodium metal with liquid ammonia in the presence of a catalyst such as iron(III) nitrate. The compound must be stored in well-sealed containers free from air or moisture.
