    摘要： 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.

    摘要： Apparatus and method for mixing of a feed liquid with a process liquid comprising a pipe having a cylindrical bore, said process liquid flowing in the pipe, a throat in the bore, the portion of the bore downstream of the throat and forming an angle between said portion and the axis of said bore of up to about 15*, at least one feed nozzle for injection of said feed liquid disposed in said pipe and extending between a source of feed liquid and the bore, the nozzle opening into the bore at the throat and being cylindrical in cross section, the axis of the nozzle forming a second angle with a portion of the axis of the bore upstream of the nozzle, the second angle being from 30*-90* whereby said feed liquid is injected at a velocity of from 2 to 15 times the velocity of the process liquid.
