Nitration of benzo[a]pyrene (BaP) with HNO3 (d = 1.38) produced a mixture of dinitroBaPs (1,6- and 3,6-isomers) and mononitroBaPs (1-, 3- and 6-isomers). Pure 1,6-dinitroBaP and 3,6-dinitroBaP were obtained by the reduction of the dinitroBaPs mixture with NaSH to yield the separable products 1-amino-6-nitroBaP and 3-amino-6-nitroBaP, followed by conversion to dinitroBaPs via the the diazonium salts
苯并[a] py(BaP)与HNO3(d = 1.38)硝化产生了dinitroBaPs(1,6-和3,6-异构体)和mononitroBaPs(1-,3-和6-异构体)的混合物。通过用NaSH还原dinitroBaPs混合物,得到纯的1,6-dinitroBaP和3,6-dinitroBaP,得到可分离的产物1-amino-6-nitroBaP和3-amino-6-nitroBaP,然后通过转化为dinitroBaPs重氮盐。测量了与二硝基BaPs的单电子还原相对应的半波电势(E1 / 2),并讨论了这些值与诱变性之间的关系。
