Question

有机化学文献中,Brine、partition
本人在做有机合成（好吧,好像很高级的样子,其实很水啦）,文献里有个句子没看懂,Solvents were removed under reduced pressure,and the residue was partitioned between EtOAc and brine.The EtOAc extract was washed with brine,dried ,filtered,and concentrated to 5.0 g (94%) of clear oil.加粗的地方不清楚啊 1.Brine是啥?2.partition是啥意思不懂啊.\x09谢谢了,

Answer 1

我不清楚你合成的产物是什么,但这步处理应该是个萃取类的过程,减压蒸馏去除溶剂得到的残余中有产品和副产物或杂质,产品应该是溶于乙酸乙酯的,而杂质应该是会溶于卤水的,所以用这个方法来分离提纯,用卤水来洗也是为了尽可能除杂
