style="text-indent:25px">一異丙醇胺(MIPA)的制備：skraup反應(yīng)是合成雜環(huán)化合物喹啉及其銜生物比較重要的方法，甘油和鄰氨基苯酚發(fā)生環(huán)化反應(yīng)得到8。羥基喹啉。濃硫酸的作用使甘油脫水成丙烯醛，并使苯胺與丙烯醛的加成物脫水成環(huán)。反應(yīng)方程式如下:升華是純化固體有機(jī)化合物的一種方法。利用升華可除去不揮發(fā)性雜質(zhì)，或分離不同揮發(fā)度的固體混合物。升華是指固體物質(zhì)不經(jīng)過(guò)液態(tài)直接轉(zhuǎn)變成蒸氣的現(xiàn)象。對(duì)有機(jī)化合物的提純來(lái)說(shuō)，重要的是使物質(zhì)蒸氣不經(jīng)過(guò)液態(tài)而直接變成固體，因?yàn)檫@樣能得到高純度的物質(zhì)。因此，在有機(jī)化學(xué)實(shí)驗(yàn)操作中，不管物質(zhì)蒸'氣是由固態(tài)直接氣化，還是由液態(tài)蒸發(fā)而產(chǎn)生的只要是物質(zhì)從蒸氣不經(jīng)過(guò)液態(tài)而直接轉(zhuǎn)變成固態(tài)的過(guò)程都稱之為升華。一般來(lái)說(shuō)，對(duì)稱性好的固體物質(zhì)，具有較高的熔點(diǎn)，且在熔點(diǎn)溫度以下具有較高的蒸汽壓，易于用升華來(lái)提純。浙江一異丙醇胺制造廠家一異丙醇胺(MIPA)的使用效率是很高的。</p><div
