<p>The invention concerns to a method for hydrogenating aliphatic dinitriles at least partly into corresponding aminonitriles. More particularly, it concerns to a method for continuous hydrogenation of dinitrile, at least partly into corresponding aminonitrile, in the presence of a hydrogenation catalyst non-dissolved in the reaction medium. The invention is characterised in that it is carried out in an equipment comprising continuous means separating the hydrogenate and the catalyst in a zone wherein the gas-liquid transfer is limited or nil, said separation and recycling of the catalyst being carried out in a time interval of not more than 30 minutes.</p> |
