化学与工业
用途与制造
应用领域
应用2-溴丙酸乙酯常用作有机合成和农药分子合成中间体,多用于农药分子的生产制备过程中,例如它是农药分子除草剂喹禾灵的关键合成中间体。
用途用作除草剂喹禾灵的专用合成中间体
用途α-溴代丙酸乙酯是除草剂喹禾灵、噁唑禾草灵、噻唑禾草灵、氟吡氯禾草灵、吡氟禾草灵、乳氟禾草灵、异丙甲草胺、敌草胺及杀菌剂甲霜灵、苯霜灵、腐霉利等的中间体。
用途用作溶剂,也用于有机合成
制备方法
生产方法其制备方法是将丙酸和赤磷投入反应瓶内,在60℃滴加溴素约3h加完,升温至100~120℃,保温搅拌6h,冷却,过滤,滤液加热蒸馏,再分馏得2-溴代丙酰溴,将2-溴代丙酰溴与无水乙醇反应即得成品。反应方程式如:CH3CH2COOH+Br2[P]→CH3CHBrCOBr+H2OCH3CHBrCOBr+C2H5OH→CH3CHBrCOOC2H5+HBr
生产方法由丙酸先后与二氯亚砜、溴反应得到2-溴丙酰氯([7148-74-5]),进而与乙醇反应制得该品。
