Question

求大神帮我翻译成英文，要求全翻译成被动句羟基喹啉衍生物是一类杂环芳香性化合物，通常为白色或淡黄色晶体。其中8-羟基喹啉类衍生物广泛应用于药物合成和化学分析等领域，因此探索它的合成方法具有重要研究价值。探索过程能够为以后合成该方面的药物提供一定帮助。5,7-二溴-8-羟基喹啉和7-溴-5-氯-8-羟基喹啉是8-羟基喹啉衍生物中的两个物质，可用作分析试剂广泛的测定和分离金属离子，也是一类极其重要印染工业和医药中间体。论文分别以2,4-二溴苯酚和2-溴-4-氯苯酚为原料设计合成路线，通过硝化、还原、成环一系列反应合成5,7-二溴-8-羟基喹啉和7-溴-5-氯-8-羟基喹啉。最后经1H NMR确证结构，获得最终目标产物。

Answer 1

Hydroxyquinoline derivatives are a class of heterocyclic aromatic compounds, usually white or pale yellow crystals. The 8-hydroxyquinoline derivatives are widely used in the fields of pharmaceutical synthesis and chemical analysis, so it is important to explore its synthetic methods. The discovery process can help to synthesize the drug in the future. 5, 7 - dibromo - 8 - hydroxyquinoline and bromine - 5 - chloro - 7-8 - hydroxyquinoline, 8 - hydroxyquinoline derivatives of two substances, can be used as an analytical reagent a wide range of determination and separation of metal ions, is also a kind of extremely important printing and dyeing industry and pharmaceutical intermediates. Paper respectively by 2, 4 - two bromine phenol and 2 - bromine - 4 - chlorine phenol as raw material to design synthetic route, was synthesized via nitration, reduction, cyclization, a series of 5, 7 - dibromo - 8 - hydroxyquinoline and bromine - 5 - chloro - 7-8 - hydroxyquinoline. Finally, the final target product is obtained by the 1H NMR confirmation structure.

Answer 2

Ask the great God to help me translate into English, requires all translation into passive sentence hydroxyl quinoline derivatives is a kind of heterocyclic aromatic compounds, usually white or yellowish crystals. 8-hydroxy quinoline derivatives are widely used in drug synthesis and chemical analysis, so it has important research value to explore its synthetic methods. The exploratory process can provide a certain degree of drug synthesis in the future.本回答被网友采纳
