style="text-indent:25px">二甘醇胺DGA是歷史悠久而富有活力的有名有機(jī)試劑之一。該試劑自1870年臺(tái)成以來(lái),幾乎在分析化學(xué)發(fā)展的各個(gè)歷史階段和各個(gè)研究領(lǐng)域中都顯了獨(dú)特非凡的作用,而獲得了極為普遍的研究和應(yīng)用。以分析試劑為重要的化學(xué)反應(yīng)性研究,以及現(xiàn)代儀器分析是當(dāng)今分析化學(xué)發(fā)展的兩大支柱,而兩者的進(jìn)一步結(jié)合已成為現(xiàn)代分析化學(xué)中的重要發(fā)展方向。近年來(lái),有機(jī)試劑在原子吸收光譜法中的作用研究及其應(yīng)用已取得了明顯進(jìn)展。在氧化亞氮-乙炔焰中,用原子吸收光譜法研究鉆絡(luò)合物,闡述了有機(jī)配位體對(duì)鉆原子化的影響。在空氣-乙炔焰中,研究了雙絡(luò)合劑體系對(duì)鏡的增感效應(yīng),展示了鏡原子在火焰中的分布,測(cè)定了稀:土合成試樣中的鏡。</p><p style="text-indent:25px">傳統(tǒng)的二甘醇胺DGA是由鄰氨基苯酚經(jīng)環(huán)合反應(yīng)制得，這個(gè)工藝存在兩個(gè)缺點(diǎn)：首先，傳統(tǒng)工藝是一次性加入發(fā)煙硫酸，無(wú)論是先在低溫下加入發(fā)煙硫酸后升溫，還是先升溫后加入發(fā)煙硫酸，一次性加入量大，硫酸反應(yīng)劇烈、不均勻，容易產(chǎn)生多種副產(chǎn)物對(duì)后續(xù)收集利用會(huì)產(chǎn)生影響，而且，一次性加入硫酸對(duì)工藝操作、控制要求都很高，二甘醇胺DGA的收率也偏低**在70%左右；其次，傳統(tǒng)工藝中離心母液是通過(guò)濃縮釜濃縮，殘?jiān)魑U處理或者通過(guò)三效蒸發(fā)器濃縮，回收產(chǎn)業(yè)作危廢處理，導(dǎo)致殘?jiān)械母视蜔o(wú)法重新回收利用，處理危廢工序繁瑣、成本過(guò)高。用三氯甲烷或苯來(lái)萃取二甘醇胺DGA鹽后再用分光光度法來(lái)測(cè)定金屬離子含量。</p><div

style="text-indent:25px">二甘醇胺DGA及其衍生物在化學(xué)分析中有多種用途，普遍用作金屬離子的萃取劑、沉淀劑及熒光分析試劑。由于二甘醇胺DGA能與金屬離子形成難溶于水的配合物,這些沉淀物經(jīng)干燥后，可以直接稱量(重量法)，也可以通過(guò)用溴量法測(cè)定二甘醇胺DGA鹽(滴定法),還可以用三氯甲烷或苯來(lái)萃取二甘醇胺DGA鹽后再用分光光度法(萃取-分光光度法)來(lái)測(cè)定金屬離子含量。通過(guò)控制反應(yīng)的條件,或選擇特殊結(jié)構(gòu)的二甘醇胺DGA衍生物作為分析試劑，可以提高反應(yīng)的選擇性和金屬離子檢測(cè)的靈敏度。長(zhǎng)期以來(lái)有關(guān)此領(lǐng)域的研究備受人們的關(guān)注。宿遷二甘醇胺DGA生產(chǎn)工藝</p><p
