| Abstract: | 3,3-dichloro-4,4′-diamino-diphenyl methane was synthesized from the system of sulfuric acid aqueous solution and o-chloroaniline by adding paraformaldehyde.The effects of the concentration of sulfuric acid,reaction time,and heating rate on yield were studied.The best technological conditions of synthesis of 3,3-dichloro-4,4′-diamino-diphenyl methane have been observed.The sulfuric acid concentration was 40%,the reaction time was 150,min,and the heating time 100,min.In the best conditions,its yield was 90%. |
| Keywords: | 3,3-dichloro-4,4′-diamino-diphenyl methane synthetize o-chloroaniline |
