如何理解這些話?

The aqueous mixture was washed twice with 100 ml of ethyl acetate and then the pH of the aqueous solution was reduced to less than 2 and extracted with 100 ml of ethyl acetate three times. The final three ethyl acetate layers were combined and dried over MgSO4 to reduce the volume to around 50 ml. 上述是一篇文獻中對產(chǎn)物的處理方式,合成的產(chǎn)物帶有鄰苯酚二羥基的結(jié)構(gòu),想請教一下各位,如何理解上述操作,該如何實驗哈!有機新手,忘幫忙! |
