能看明白,就是主要是几个细节没搞不清楚:怎么通过分液漏斗同时加入?尝试滴加和一次性加入都没有得到目标产物。求高人指点下。 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. |
