Abstract
Las lactamas cíclicas se preparan mediante la reaccion de amino carbonitrilos con agua, en fase líquida, en presencia de catalizadores heterogéneos basados en dioxido de titanio con un contenido de rutilo en el rango desde 0.1 a 95 % por peso y un contenido de anatasa en el rango de 99.9 a 5 % por peso, en cada caso con base en el contenido total del dioxido de titanio.
