An Efficient Continuous Process For Manufacturing Of 4 Aminodiphenylamine From Aniline And Nitrobenzene
Abstract: An efficient continuous manufacturing process for 4 aminodiphenylamine by coupling aniline with nitrobenzene in the presence of tetramethylammonium hydroxide (TMAH) as a base using flow reactors wherein base decomposition is considerably reduced by optimizing base quantity process conditions and process equipment. Accordingly in brief summary one embodiment of the present invention is a process which comprises one or more of the steps of reacting aniline and nitrobenzene in the presence of water and TMAH as a base in a continuous manner by feeding the reactants to a series of continuous flow reactors while continuously distilling off an aniline water mixture under reduced pressure such that the water to total base molar ratio is less than 0.6:1 at the flow reactors outlet and the water to unbound TMAH molar ratio is about 4: 1 in the reaction product.
