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,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行溴化反應,控制溴化劑的用量,使發(fā)生單溴化反應得到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。反應過程中利用薄層色譜法進行跟蹤檢測,每步反應的產(chǎn)物均通過紅外光譜測定進行了定性鑒定。 |

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 |
