Aidhm
Is idirmheánach orgánach tábhachtach é bromoethylbenzene sna tionscail cheimiceacha, cógaisíochta agus leachtacha leachtacha . le forbairt thapa an tionscail criostail leachtach, tá a úsáid mar bhunábhar bunúsach ag méadú ó lá go lá .
Modh sintéiseach
Add 4000mL of diethylene glycol and 900g of potassium hydroxide to a 5000mL four necked flask equipped with a stirrer, thermometer, and reflux condenser. Stir and slowly raise the temperature to around 60℃. After the potassium hydroxide dissolves, add 754.7g of hydrated phenanthrene and 800g of p-bromoacetophenone in sequence. Slowly raise the temperature to reflux for 2 hours. Change reflux to distillation, add hot water dropwise to the reactants, and slowly evaporate until no oil droplets appear in the distillate, and stop the reaction. Transfer the distillate to a separating funnel, separate the Céim uiscí, bain an chéim uiscí le dichloroethane, cuir na céimeanna orgánacha le chéile, nigh le haigéad hidreaclórach caol go dtí go bhfuil siad aigéadach go lag, ansin nigh le huisce salann sáithithe trí huaire, agus tirim . scagaire, déchlóineatán gaile faoi ghnáthbhrú, agus gaile an táirge faoi bhrú.
