Production of methylene-diphenylamine, useful for conversion into methylene-diphenyl-isocyanate

Production of methylene-diphenylamine, useful for conversion into methylene-diphenyl-isocyanate

In a process for the production of methylene-di-phenylamine from aniline (A) and formaldehyde (F) in presence of a protic acid, the condensation is carried out at 80-250 deg C and the reaction mixture in the condensation stage is homogenized in a dynamic or static mixer.
