摘要
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%.关键词
