Abstract: The invention relates to a method for producing lactams by means of cyclizing hydrolysis of aminonitriles with water in the gas-phase on catalysts which contain oxides or mixed oxides of metals of groups 3, 4, 5, 13 and/or 14 of the periodic table, and optionally one additional metal oxide of groups 6, 7, 8, 9 and/or 10. In addition, the catalysts comprise a phosphate, carbonate, silicate, arsenite, arsenate, antimonite, antimonate and/or nitrate of the aforementioned metals and/or a sulfate of the aforementioned metals when metal oxides of groups 6, 7, 8, 9 or 10 are present.
