2em;">過碳酸鈉是由碳酸鈉、過氧化氫和水三組分體系利用氫鍵所形成的不穩(wěn)定的復(fù)合物，由于過碳酸鈉在高溫下容易分解，所以反應(yīng)必須在低溫下進(jìn)行。一般在溶液中發(fā)生如下反應(yīng)：</p><p style="text-indent: 2em;">主反應(yīng)：2Na2CO3+3H2O2==2Na2CO3·3H2O2</p><p style="text-indent: 2em;">副反應(yīng)：2H2O2=2H2O +O2↑</p><p style="text-indent: 2em;">2Na2CO3+2H2O2→2Na2CO3+2H2O+O2↑　不同的方法可以制得不同形式和規(guī)格的過碳酸鈉產(chǎn)品，工業(yè)上過碳酸鈉生產(chǎn)工藝分為干法和濕法2種。</p><p

style="text-indent: 2em;">干法是將無水碳酸鈉置于流動床上，在熱空氣吹沸下向碳酸鈉上連續(xù)噴灑過氧化氫溶液，一步得到過碳酸鈉。此法流程短，產(chǎn)率高。缺點(diǎn)是設(shè)備復(fù)雜、技術(shù)條件控制嚴(yán)格、能耗高和產(chǎn)品穩(wěn)定性差。當(dāng)前只有德國采用。 </p><p style="text-indent: 2em;">濕法生產(chǎn)是將過氧化氫水溶液與飽和碳酸鈉溶液置于反應(yīng)釜中，控制反應(yīng)溫度在5。C以下進(jìn)行反應(yīng)，然后加鹽析劑使過碳酸鈉結(jié)晶，分離，低溫干燥制得產(chǎn)品。用該法制得的產(chǎn)品中雜質(zhì)比干法少，且工藝較為簡單，設(shè)備容易制造，技術(shù)難度低，過程控制簡單，產(chǎn)品穩(wěn)定性好，母液可以循環(huán)使用。合理地控制加料、反應(yīng)和結(jié)晶時間，都有利于保證產(chǎn)品的收率和縮短生產(chǎn)周期。</p><p style="text-indent: 2em;">濕法是當(dāng)前國內(nèi)外生產(chǎn)過碳酸鈉普遍采用的方法，除德國外，幾乎所有過碳酸鈉生產(chǎn)廠家都采用該方法進(jìn)行生產(chǎn)。比如我國的過氧化物生產(chǎn)企業(yè)高施貝爾化工。該生產(chǎn)方法主要包括噴霧法、結(jié)晶法和醇析法3種生產(chǎn)工藝。</p><p><br/></p></div> <div
