Ua txheej txheem tsim khoom
Synthetic txoj kev ntawm resorcinol
- Kauj Ruam ①: Acetylation
Resorcinol undergoes friedel - actic acid catalicid catalicid catalide, yielding 2,4-dihydrophenophenone raws li nruab nrab.
- Kauj Ruam ②: Methylation & Phoulation
Lub Intermediate 2,4 {{-}}} ecymelicization kom tau txais ntshiab pa paols (2}} hydroxy-4'-methoxyacetophenone, cuhtoxyacetophenone, c₉h₁₀o₃).
