[求助]
求助翻譯，主要是幾個(gè)操作的細(xì)節(jié)沒搞不清楚

能看明白，就是主要是幾個(gè)細(xì)節(jié)沒搞不清楚：怎么通過分液漏斗同時(shí)加入？嘗試滴加和一次性加入都沒有得到目標(biāo)產(chǎn)物。求高人指點(diǎn)下。 While they were stirred vigorously under a stream of nitrogen, half of a solution of 25.6g of ammonium chloride in 100 ml of water was added, all at once, through a dropping funnel thereinto. The internal temperature rose suddenly to 70 to 80℃，and mild heating-up and reflux took place. After the reflux subsided a little, the rest of the solution was added, again all at once, followed by stirring. |
