    Abstract: A PROCESS FOR THE CONTINUOUS PRODUCTION OF LACTAMS WHICH ARE STARTING MATERIALS FOR NYLON-TYPE POLYAMIDES, FROM CYCLIC KETOXIMES, USING MINERAL ACIDS AS A CATALYST, CYCLING OXIME AND ACID BY WAY OF NOZZLES FROM CONTINUOUS MIXERS IN LIEU OF USING AGITATOR VESSELS. THE NOZZLE DELIVERY SPEED OF THE OXIME AND OF THE ACID IS AT LEAST TWICE THE FLOW VELOCITY OF THE CYCLE AND THE VOLUME PROPORTIONS OF THE PRODUCT PUMPED PER HOUR TO OXIME INTRODUCED IS 50:1 TO 150:1.
