幫我翻譯成英語,不能詞堆詞哦 本實(shí)驗用新制試劑亞硝酸正丁酯與5-碘-2-氨基吡啶發(fā)生重氮化反應(yīng)制得5-碘-2-氨基吡啶重氮鹽(產(chǎn)率 = 82.60 %),再用2,4-二氨基甲苯與重氮鹽進(jìn)行偶聯(lián),合成了碘代吡啶偶氮類試劑5-(5-碘-2-吡啶偶氮)-2,4-二氨基甲苯粗品(產(chǎn)率 = 69.54 %),然后對粗產(chǎn)品進(jìn)行兩次重結(jié)晶得暗紅色固體結(jié)晶,并用元素分析法、紅外光光譜法、核磁共振氫譜法對其進(jìn)行表征。最終結(jié)果表明5-I-PADAT的結(jié)構(gòu)與設(shè)計的相符合。 |

| In this experiment, n-butyl nitrite reagent new system with a 5 - iodo - 2 - aminopyridine diazotization reaction occurred to give 5 - iodo - 2 - aminopyridine diazonium salt (yield = 82.60%) followed by 2,4-- diaminotoluene and coupling the diazonium salt, synthesis of azo reagent iodo-pyridine 5 - (5 - iodo - 2 - pyridyl azo) -2,4 - diamino toluene crude product (yield = 69.54%) , and then the crude product was recrystallized twice a dark red crystalline solid and characterized by elemental analysis, infrared spectroscopy, proton nuclear magnetic resonance spectroscopy to characterize them. Final results showed that the 5-I-PADAT structure and design of the match. |
