Abstract (en)
[origin: WO02074739A1] The invention relates to a method for the hydrolytic cyclisation of an aminonitrile compound to give a lactam in the presence of a catalyst, in particular a method for the hydrolytic cyclisation of an aminonitrile compound in the presence of a solid catalyst of a clay type. The invention relates in particular to the preparation of ε-caprolactam by hydrolytic cyclisation of the aminocapronitrile.
