酚羥基和鹵代烴反應方程式

苯酚可與濃溴水發生取代反應

苯酚+3Br₂→2，4，6-三溴苯酚+3HBr

鹵代烴在鹼性條件下水解

CH₃CH₂Br+NaOH→CH₃CH₂OH+NaBr條件 H₂O

五鹵代烴水解反應（取代反應）CH3CH2Br + H2O CH3CH2OH + HBrCH3CH2Br + NaOH CH3CH2OH + NaBr消去反應CH3CH2Br+ NaOH CH2 = CH2 + NaBr +H2O六 醇乙醇與鈉反應     

2CH3CH2OH + 2Na 2CH3CH2ONa + H2↑

乙醇催化氧化 2CH3CH2OH + O2 2CH3CHO + 2H2O
