　　制法二

　　過氧化氫

　　此方法涉及無機(ji)化(hua)合物制(zhi)備(bei)領域，特別涉及從申(shen)(shen)請(qing)號為(wei)87103988專利(li)申(shen)(shen)請(qing)中(zhong)(zhong)所得陰級產物的過(guo)(guo)氧(yang)化(hua)鈉(na)水(shui)(shui)(shui)溶(rong)液制(zhi)備(bei)過(guo)(guo)氧(yang)化(hua)氫的方法。用磷(lin)酸或(huo)磷(lin)酸二(er)氫鈉(na)將過(guo)(guo)氧(yang)化(hua)鈉(na)水(shui)(shui)(shui)溶(rong)液中(zhong)(zhong)和至pH9.0~9.7，使(shi)生(sheng)成Na2HPO4和H2O2，將所說(shuo)的Na2HPO4和H2O2水(shui)(shui)(shui)溶(rong)液冷卻(que)到(dao)(dao)+5~-5℃，使(shi)絕大部分(fen)Na2HPO4以Na2HPO4·10H2O水(shui)(shui)(shui)合物形(xing)式析出，再(zai)(zai)在離(li)心分(fen)離(li)器中(zhong)(zhong)將含(han)有Na2HPO4·10H2O水(shui)(shui)(shui)合物和過(guo)(guo)氧(yang)化(hua)氧(yang)水(shui)(shui)(shui)溶(rong)液混(hun)合物進行分(fen)離(li)，分(fen)離(li)出該水(shui)(shui)(shui)合物，隨后再(zai)(zai)對含(han)有少量Na2HPO4的過(guo)(guo)氧(yang)化(hua)氫水(shui)(shui)(shui)溶(rong)液進行蒸發和分(fen)餾(liu)，得到(dao)(dao)約30%H2O2產品。

　　制法三

　　用電解60%的硫酸，得到過二硫酸，再經水解可得濃度為95%的雙氧水。
