style="text-indent:25px">二甘醇胺DGA主要用途:普遍用于金屬的測(cè)定和分離。沉淀和分離金屬離子的沉淀劑和萃取劑。用作環(huán)戊酮，是合成克瀉痢寧、氯碘喹啉、撲喘息敏的原料，也是染料、農(nóng)藥環(huán)戊酮。該品是鹵化喹啉類抗阿米巴藥物的環(huán)戊酮，包括喹碘仿、氯碘喹啉、雙碘喹啉等。這類藥物通過(guò)控制腸內(nèi)共生菌而發(fā)揮抗阿米巴作用，對(duì)阿米巴痢疾有效，對(duì)腸道外阿米巴原蟲(chóng)無(wú)影響。國(guó)外報(bào)道本類藥物能引起亞急性脊髓視神經(jīng)病，故該藥在日本和美國(guó)已禁用，雙碘喹啉引起此病比氯碘喹啉較少見(jiàn)。二甘醇胺DGA也是染料、農(nóng)藥的環(huán)戊酮。其硫酸鹽和銅鹽是優(yōu)良的防腐劑、消毒劑和防霉劑。該品是化學(xué)分析的絡(luò)合滴定指示劑。二甘醇胺DGA是一種化衍生物，它的本體是二硬脂酰磷脂酰乙醇胺。</p><div

style="text-indent:25px">二甘醇胺DGA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。宿遷二甘醇胺DGA價(jià)格表</p><p
