摘要 本論文以芘為原料，通過兩種方案合成1-羥基芘。方案一合成過程如下：芘在三水硝酸銅和醋酸酐的混合體系中硝化生成1-硝基芘，1-硝基芘由氯化亞錫還原得到1-氨基芘，1-氨基芘經(jīng)重氮化反應(yīng)，然后水解得到1-羥基芘。方案二合成過程如下：以溴作為溴化劑對芘進(jìn)行溴化反應(yīng)，控制溴化劑的用量，使發(fā)生單溴化反應(yīng)得到1-溴芘，1-溴芘加入到甲醇鈉溶液中通過加入碘化亞銅和DMF溶劑生成1-甲氧基芘，1-甲氧基芘溶于二氯甲烷中，利用三氯化鋁使醚鍵斷裂生成1-羥基芘。反應(yīng)過程中利用薄層色譜法進(jìn)行跟蹤檢測，每步反應(yīng)的產(chǎn)物均通過紅外光譜測定進(jìn)行了定性鑒定。 |

Abstract 1 – Hydroxypyrene was synthesized in two methods with pyrene as starting material. In one method, first 1 - nitro-pyrene were synthesized in mixed system of copper nitrate trihydrate and acetic oxide after addition of pyrene. 1-nitro-pyrene was reduced to 1 - amino-pyrene, which was then transformed to final product 1 – hydroxypyrene after diazotization. In another method, pyrene first reacts with bromine to yield 1-bromo pyrene. This process is based on controlled usage of bromine. 1-Bromo pyrene was added to sodium methoxide solution to yield 1- methoxy pyrene with CuI and DMF applicated in the same solution. 1- Methoxy pyrene was dissolved in dichloromethane and transformed into 1-hydroxypyrene with aluminum chloride breaking ether bond. The synthesis process was traced with TLC and product was characterized qualitatively with IR |
