    Abstract: A method for preparing lactams by cyclizing hydrolysis of a corresponding aminonitrile is described. A method for manufacturing a lactam by reacting an aminonitrile with water in the presence of a catalyst involving placing the water and the aminonitrile in contact in vapor phase, passing the mixture of vapors through a bed of catalyst arranged in at least one tube forming a reaction chamber and recovering the lactam at the outlet of the tube is also described.

    Abstract translation: 描述了通过环化相应的氨基腈的水解制备内酰胺的方法。 一种在催化剂存在下使氨基腈与水反应的方法,所述催化剂涉及使水和氨基腈气相接触,使蒸汽混合物通过排列在形成反应的至少一个管中的催化剂床 还描述了在管的出口处回收内酰胺的腔室。
