Abstract

"PROCESSO PARA PREPARAçãO DE 4-AMINODIFENILAMINAS". A presente invenção refere-se a um processo para produzir 4-aminodifenilamina ou derivados substituídos da mesma compreendendo as etapas de por uma anilina ou derivado de anilina e nitrobenzeno ou derivado de nitrobenzeno em contato de reação; e fazer reagir a anilina e o nitrobenzeno em uma zona confinada a um tempo e temperatura adequados, na presença de uma mistura compreendendo uma base forte e um catalisador de transferência de fase adequado e um oxidante para produzir um produto intermediário de 4-aminodifenilamina. Alternativamente, a mistura pode compreender um sal inorgânico ou sal orgânico metálico tendo um cátion que seria um cátion adequado de uma base inorgânica forte, e um oxidante e base orgânica, a mistura não incluindo um produto de reação de betaína e uma base inorgânica forte. O produto intermediário de 4-aminodifenilamina é reduzido para produzir 4-aminodifenilamina ou derivados substituídos da mesma."PROCESS FOR PREPARING 4-AMINODYPHENYLAMINES". The present invention relates to a process for producing 4-aminodiphenylamine or substituted derivatives thereof comprising the steps of by an aniline or nitrobenzene derivative or nitrobenzene derivative in reaction contact; and reacting aniline and nitrobenzene in a confined zone at a suitable time and temperature in the presence of a mixture comprising a strong base and a suitable phase transfer catalyst and an oxidant to produce a 4-aminodiphenylamine intermediate product. Alternatively, the mixture may comprise an inorganic salt or metallic organic salt having a cation that would be a suitable cation of a strong inorganic base, and an oxidant and organic base, the mixture not including a betaine reaction product and a strong inorganic base. The 4-aminodiphenylamine intermediate product is reduced to produce 4-aminodiphenylamine or substituted derivatives thereof.
