摘要： The present invention relates to a process for separating the water from an aqueous lactam solution. It applies more particularly to a mixture resulting from the reaction between an aminonitrile and water (this reaction also being called cyclizing hydrolysis). The subject of the invention is a process for separating the water from an aqueous lactam solution, which process is economical both from the standpoint of the investment necessary for its implementation and from the standpoint of the operating cost.

摘要： The present invention relates to a process for the hydrogenation of compounds comprising nitrile or nitro functional groups to amine, aminonitrile or aminonitro compounds. The invention provides a continuous process for the hydrogenation of compounds comprising nitrile or nitro functional groups to amine or aminonitrile compounds in the presence of a heterogeneous hydrogenation catalyst in divided form and of a basic compound. The reaction is employed in a stirred reactor comprising an external loop for circulating the reaction mixture, allowing one portion of the hydrogenated products to be separated without withdrawing the catalyst, by using tangential filtration. The process of the invention applies especially to the hydrogenation of adiponitrile to an aminocapronitrile/hexamethylenediamine mixture.

摘要： The invention concerns a method for evaporating aminonitrile and water in conditions limiting or eliminating the formation of heavy by-products in particular amino-carboxylic acid oligomers. To avoid said inconvenience, said method for evaporating aminonitrile and water is characterised in that the water in vapour state serves as balance gas for evaporation.
