【摘要】 研究了四川南桐风化煤硝酸氧化降解制取硝基腐植酸的可行性。用正交试验方法找出适宜的反应条件为：硝酸的质量分数３５％；煤酸比３．５；反应时间１５分钟；反应温度３６９Ｋ．所制得硝基腐植酸质量指标为：Ｗｆ２．ｇｉ％；Ａｇ１４．０６％；ＨＡｇ７８．２８％；Ｎｇ１．６２％．更多还原

【Abstract】 A raseach has been done on the possibility of producing nitriochumic acid fromweathered coal of Nantong,Sichuan,oxidised by nithic acid.The optimun reacting conditions,whichare found through the way of orthogonal experiment,are suggested as follows:concentration ofHON3 35%,rate of HON3 to coal 3.5,reacting take 15 min,and reaction temperature 369 K. Thecomposition of product is Wf 2. 91 %;Ag 14.06%;HAg 78.28%;Ng 1.62%.更多还原
