用途
[编辑]HBr
- ROH + HBr → R+OH2 + Br– → RBr + H2O
HBr
- RCH=CH2 + HBr → RCH(Br)–CH3
如在
HBr
- RC≡CH + HBr → RCH(Br)=CH2
- RC(Br)=CH2 + HBr → RC(Br2)–CH3
此外,HBr也可
工 业制取
[编辑]实验室 制 备
[编辑]实验
- NaBr(s) + H2SO4(aq) → NaHSO4(s) + HBr(g)
- 2HBr(g) + H2SO4(aq) → Br2(g) + SO2(g) + 2H2O(l)
- C10H12 + 4Br2 → C10H8Br4 + 4HBr(g)
C6H5OH+3Br2→C6H2Br3OH(
PhCOOH + LiBr → PhCOOLi + HBr↑
纯净氢气与溴在铂催
- Br2 + H2 → 2HBr(g)
- Br2 + H3PO3 + H2O → H3PO4(s) + 2HBr(g)
