Abstract
Un procedimiento para preparar lactamas por ciclacion hidrolítica de aminonitrilos en fase gaseosa en presencia de un catalizador de fosfato metálico,comprende utilizar un catalizador que comprende uno o más oligofosfatos de formula general (I): M(POa)b, donde M es un metal del grupo 3 o 4 de la tablaperiodica, incluídos los lantánidos, a es > 2,5 y < 4,0 y b es tal que se asegure la electroneutralidad, o una mezcla de uno o más oligofosfatos deformula general (I) con una o más sales adicionalesde un metal del grupo 3 o 4 de la tabla periodica, incluidos los lantánidos, con un ácidoinorgánico.
