The intermediate products of indole, quinoline, and isoquinoline were proved, and 2-isopropyl-6-methylaniline were originally detected in the degradation of 2-methylquinoline.
验证了吲哚、喹啉和异喹啉的降解中间产物，发现了2-甲基喹啉缺氧降解的中间产物2-异丙醇-6-甲苯。

The p-methylaniline and other impurity in the crude product are adsorbed by active carbon and the purified 4B acid is precipitated out by acidic solution from middle compartment.
In this paper, polymer films were prepared with o-toluidine, p-chloroaniline, m-trifluoro methylaniline and 5-trifluoromethyl-1,3-diaminobenzene as monomer by electrochemical method.
