Embodiment
[0017] Embodiment: The embodiment of the present invention is based on the transformation of a 180t / a p-phenylenediamine reductive alkylation production device. The geometric dimensions of the equipment are consistent with the actual production device equipment. The pipes, valves and measuring elements are all in actual proportions. The display instrument is the same as the actual device.
[0018] Qualified p-phenylenediamine and methyl ethyl ketone are mixed in the batching tank 11; after confirming that they are fully dissolved, the solution is sent from the batching tank 11 to the middle tank 12, the solid matter is separated, and the supernatant is sent to the reduction tank 13; hydrogen and catalyst, the heat of reaction is provided by steam, and after the reaction is completed, the reaction liquid is sent to rectification still 14; by steam heating, N,N'-di-sec-butyl-p-phenylenediamine is separated from impurities in rectification still 14; The N,N'-di-sec-butyl-p-phenyl...
