氢溴酸吡啶盐的合成及其应用

Synthesis and Application of Pyridinium Hydrobromide

氢溴酸吡啶盐是7-ADCA合成中重要的化工中间体,本文主要采用纯吡啶及7-ADCA合成产生废甲苯中的吡啶作为原料,摸索氢溴酸吡啶盐的合成,并将合成的氢溴酸吡啶盐应用于7-ADCA合成中,比较不同工艺得到的氢溴酸吡啶盐对扩环过程的影响。

Pyridinium hydrobromide is an important chemical intermediate in the synthesis of 7-ADCA,In this paper,the pure pyridine and the pyridine from the waste toluene of 7-ADCA were used as material.The synthesis of pyridinium hydrobromide was studied.We applied the pyridinium hydrobromide to the synthesis of 7-ADCA and compared the diffrent effects of pyridinium hydrobromide from different processes on 7-ADCA.
