<p>The present invention relates to a method of manufacturing an organic amino compound from an organic nitro compound which hydrogenates an organic nitro compound into an organic amino compound by a catalyst by using a hydrogen-containing gas stream and monitors a hydrogenation process by analyzing a secondary product formed during hydrogenation. The method measures the concentration of the gaseous secondary product of at least one kind in a gas phase and increases the hydrogenating activity of the catalyst when a concentration drops to less than a minimal concentration which is previously regulable. Additionally, the present invention relates to an apparatus for forming the method.</p> |
