Process for the production of aromatic amines |
摘要 |
A process for the production of aromatic amines which comprises the reduction of an aromatic compound containing at least two nitro groups with hydrogen in the presence of a catalyst is disclosed. The reaction is carried out so as to maintain up to 10% by weight of reaction intermediates (aminonitrites) and the solution produced is treated to recover the aromatic amine with a purity of over 99% and a mixture consisting of aromatic amine and reaction intermediates is recycled to the reactor. |
