Abstract: In the oxidative dehydrogenation of organic compounds by means of free halogen, it is an advantage to obtain the free halogen as a result of ammonium halide splitting by bringing an aqueous ammonium halide solution into contact with a flame produced by burning hydrogen or combustible organic gases with oxygen or oxygen-containing gases.

Abstract: THE INVENTION RELATES TO A METHOD OF MIXING A GAS WITH LIQUIDS IN A TUBULAR REACTOR BY FEEDING THE GAS AND THE LIQUIDS TO A MIXING zONE. THE INVENTION ALSO RELATES TO AN SEPARATUS FOR CARRYING OUT THIS METHOD. RAPID MIXING ID EFFECTIVE BY FEEDING A STREAM OF LIQUID TO THE MIXING ZONE THROUGH ONE OR MORE NOZZELS WHOSE AXS EXTEND IN THE SAME DIRECTION AS THE AXIS OF THE MIXING ZONE, IN INJECTED LIQUID HAVING A VELOCITY OF FROM 5 TO 100 M./S., WHILST A SECOND STREAM OF LIQUID OF MUCH LOWER VELOCITY IS INTRODUCED INTO THE REACTOR INLET ZONE SURROUNDING SAID NOZZEL. THE GAS IS FED TO THE MIXING ZONE THROUGH ONE

OR MORE GAS INLETS LOCATED NEAR THE ORIFIECES OF THE LIQUID NOZZELS. THE MEAN CROSS-SECTIONAL AREA OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE CROSS-SECTIONAL AREA OF THE ORIFICES OF THE LIQUID NOZZLES AND THE LENGTH OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE HYDROLIC DIAMETER THEREOF. THE METHOD AND APPARATUS ARE PARTICULARLY SUITABLE FOR CARRYING OUT REACTIONS IN WHICH SHORT RESIDENCE TIMES ARE DESIRABLE AND THE REACTION PRODUCTS MUST NOT RECONTACT THE STARTING MATERIALS.

Abstract: AN IMPROVED PROCESS FOR THE RECOVERY OF PHTHALONITRILES FROM HOT REACTION GASES CONTAINING THE SAME BY CONTACTING THE HOT REACTION GASES WITH A COOLANT WHICH IS AT A TEMPERATURE OF FROM 40* TO 200*C. AND COOLING THEM DOWN AT A RATE OF MORE THAN 350*C. PER SECONDS, THE COOLANT BEING WATER, BENZONITRILE OR O-TOLUNITRILE WHICH FROM RRECYCLING CONTAINS 2 TO 40% PHTHALONITRILES. O-PHTHALONITRILE IS SUITABLE FOR THE PRODUCTION OF PHTHALOCYANINES WHICH ARE VALUABLE PIGMENTS, TEREPHTHALONITRILE AND ISOPHTHALONITRILES CAN BE REDUCED TO THE CORRESPONDING DIAMINES WHICH ARE STARTING MATERIALS FOR THE MANUFACTURE OF POLYAMIDES WHICH CAN BE USED FOR THE PRODUCTION OF FIBERS.
