肼解反应操作.!
反应条件?催化剂选择?溶剂选择?后处理方法邻苯二甲酰亚胺与水合肼的反应.
你给我的答案又是去复制的，你们自己没有做过这类反应吗？
提问者采纳
滤液中加入500ml干乙醚。将所有的纯品叔丁胺盐酸盐用布氏漏斗过滤收集。给你个例子如下叔丁胺盐酸盐的合成。合并滤液和洗液：将粗品溶解于500毫升无水乙醇，熔点270-290 并升华，加入绝对乙醚（乙醇量的50％）。在装有球型回流冷凝器的2升瓶中加入203克（1摩尔）叔丁基邻苯二甲酰亚胺。如果再有不溶性物质出现仍然用过滤方法将其除去，过滤去除掉任何不溶性物质，一升95％的乙醇和59克（1摩尔）的85％水合肼，再将滤液浓缩至约300-350毫升。溶液加热至回流2小时，但酸不要过量。加入1升水。重量约为79-97克（72-88％），并用4x100ml 95％乙醇冲洗，冷却。将反应产生的大量沉淀物邻苯二甲酰肼收集到直径15厘米的布氏漏斗中：粗胺盐酸盐用无水乙醇溶解，加入盐酸（约100毫升。）调节溶液ph至刚果红试纸显强酸性,减压浓缩至约200毫升，并在真空干燥器中干燥，每克粗品约用无水乙醇5毫升，过滤除去不容物，然后减压蒸除所有溶剂。粗品胺盐酸盐按如下方法精制。具体如下，将以上溶液在冰箱冷却析晶几个小时化学的东西很多 都得参考文献，谁能保证什么反应都做过
