帮我翻译成英语,不能词堆词哦
本实验用新制试剂亚硝酸正丁酯与5-碘-2-氨基吡啶发生重氮化反应制得5-碘-2-氨基吡啶重氮盐(产率 = 82.60 %),再用2,4-二氨基甲苯与重氮盐进行偶联,合成了碘代吡啶偶氮类试剂5-(5-碘-2-吡啶偶氮)-2,4-二氨基甲苯粗品(产率 = 69.54 %),然后对粗产品进行两次重结晶得暗红色固体结晶,并用元素分析法、红外光光谱法、核磁共振氢谱法对其进行表征。最终结果表明5-I-PADAT的结构与设计的相符合。

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.
