有做过达夫反应的大侠么?有些有机化合物在盐酸中较水中溶解度大，再说你这个体系是醋酸溶剂情况下，加了盐酸或者加水，依然是醋酸体系，只是浓度降低，并未根本改变，这不是关键 关键的是后处理，从结构看，不管是原料，产物，副产物，他 ... 我找了这个反应的十篇文献，基本上都只是这：7-hydroxy-4-methyl coumarin(0.03 mol) and hexamine (0.07 mol) in glacial acetic acid (50 mL) were heated for 4–5 h and then 20% HCl (75 mL) was added with further heating for 20 min, cooled and extracted with ether. Pale yellow solid of 8-formyl-7-hydroxy-4-methyl coumarin, which was obtained after extraction, was recrystallized from ethanol.请教一下，后处理怎么进行。比如盐酸水解，水解到怎样的程度？乙醚萃取又是怎样的操作？乙醚旋掉后又该怎么办？有机接触不深，还望大神不吝赐教。方便的话留个邮箱或者扣扣，非常感谢。查看更多
