【摘要】 以 6-甲氧基 - 8-氨基喹啉为原料 ,经重氮化后与间苯二酚偶联 ,合成了有机试剂 4- (6-甲氧基 - 8-喹啉偶氮 ) -间苯二酚 (简称 MQAR) ,用 DMF重结晶精制。通过TL C、EA、UV- VIS、IR、1 HNMR等分析手段 ,对合成产物进行分析和结构鉴定 ,确证得到了 MQAR纯品 ,产品熔点为 1 94℃。更多还原

【Abstract】 methoxyl 8 quinolineazo) resorcinol (abbr.MQAR),an organic reagent,has been synthesized by coupled reaction of diazotized 6 methoxyl 8 aminoquinoline with resorcinol, and purified with N,N dimethyl formamide recrystallization method. Analysis and characterization of synthesized product using thin layer chromatography (TLC), elementary analysis (EA), UV VIS absorption spectrometry, infra red absorption spectrometry (IR) and nuclear magnetic resonance (NMR) etc. indicate that the synthesized product to be pure MQAR with melting point of 194℃.更多还原
