Abstract: 1. IN A PROCESS FOR CONTINUOUS PRODUCTION OF AN AQUEOUS SOLUTION OF PROPYLENE CHLOROHYDRIN BY REACTING PROPYLENE WITH AN AQUEOUS CHLORINE SOLUTION, RECYCLING SOME OF THE REACTION SOLUTION AND ADDING MAKE-UP WATER, THE IMPROVEMENT WHICH COMPRISES LOADING THE RECYCLED SOLUTION WITH CHLORINE TO SUCH AN EXTEND THAT THE LIMIT OF SOLUBILITY OF THE CHLORINE IS NOT EXCEEDED, BY MEANS OF A TWO FLUID NOZZLE, METERING THE PROPYLENE TO BE REACTED INTO THE CHLORINE-LADEN SOLUTION AT A PRESSURE OF FROM 2 TO 20 ATMOSPHERES ABSOLUTE AND AT A TEMPERATURE OFF FROM 10* TO 80* C., BY MEANS OF A TWO FLUID NOZZLE ALLOWING THE REACTION MIXTURE TO REACT IN ONE OR MORE PARALLEL TUBES WITH TUBULENT FLOW IN THE SAME PRESSURE RANGE WITH A RESIDENCE TIME OF NOT MORE THAN TEN SECONDS, RELEASING THE PRESSURE, WITHDRAWING SOME OF THE PROPYLENE CHLOROHYDRIN SOLUTION AS PRODUCT AND RECYCLING THE REMAINDER OF THE PROPYLENE CHLOROHYDRIN SOLUTION WHEREIN AT THE POINT OF INCORPORATION OF THE CHLORINE AS WELL AS AT THE POINT OF INCORPORATION OF PORPYLENE THE RECYCLE LIQUID IS INRODUCED AT A VELOCITY OF FROM 2 TO 100 METERS PER SECOND THROUGH SAID TWO-FLUID NOZZLES AND THEN INTO A MIXING ZONE EXTENDING IN THE DIRECTION OF FLOW WHOSE DIAMETER IS FROM 1.5 TO 50 TIMES THE MEAN OUTLET DIAMETER OF THE LIQUID NOZZLES AND WHOSE LENGTH IS FROM 3 TO 30 TIMES ITS HYDRAULIC DIAMETER, AND ALLOWING THE MIXTURE TO COMPLETE THE REACTION IN ONE OR MORE PARALLEL REACTION TUBES.
