    Abstract: Dehydrogenation of isobutyronitrile, ethylbenzene or methyl isobutyrate with iodine and oxygen into methacrylonitrile, styrene or methyl methacrylate at 400* to 800*C is carried out in a reaction chamber in which there are arranged, in the direction of flow of the bulk of the reactants introduced through a nozzle, coaxially from inside to outside first a mixing zone and then a circulation tube.

    Abstract translation: 在400℃至800℃下，将异丁腈，乙苯或异丁酸甲酯与碘和氧进行甲基丙烯腈，苯乙烯或甲基丙烯酸甲酯的脱氢反应，其中反应室沿大部分反应物的流动方向排列 通过喷嘴引导，从内到外同轴地设置混合区，然后是循环管。

    Abstract: THE PRODUCTION OF 2,2-DIMETHYL1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY HEATING 2,2-DIMETHYL-3-HYDROXYPROPANAL (PRAPARED BY THE REACTION OF FORMALDEHYDE WITH ISOBUTYRALDEHYDE IN THE PRESENCE OF TERTIARY AMINES) IN THE PRESENCE OF AN ORGANIC SALT OF A TERTIARY AMINE. AS COMPARED WITH THE PRIOR ART METHODS, THE PROCESS ACCORDING TO THE INVENTION GIVES 2,2-DIMETHYL-1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY A SIMPLER AND MORE ECONIMICAL METHOD, IN HIGHER PURITY AND WITH A HIGHER YIELD WITH REFERENCE TO THE STARTING MATERIAL AND WITH A HIGHER SPACE-TIME YIELD OF PURE END PRODUCT. THE COMPOUND WHICH CAN BE PREPARED BY THE PROCESS ACCORDING TO THE INVENTION IS A MORE VALUABLE STARTING MATERIAL FOR THE PRODUCTION OF SYNTHETIC RESINS AND PLASTICIZERS.

    Abstract: 1. A PROCESS FOR CARRYING OUT AN EXOTHERMIC CATALYTIC HYDROGENATION WITH MOLECULAR HYDROGEN OF A CARBON-CARBON TRIPLE OR DOUBLE BOND, AN AROMATIC RING, A CARBONYL GROUP, A NITRO GROUP, A NITRILE GROUP, AN OXIME GROUP, AN AMINOIXDE GROUP, AN ACID CHLORIDE GROUP, A BENZYL ESTER GROUP, OR A BENZYL EHTER GROUP OF AN ORGANIC COMPOUND IN AN EXOTHERMIC REACTION IN A BODY OF LIQUID HAVING SUSPENDED OR DISSOLVED THEREIN A SOLID, FINELY DIVIDED HYDROGENATION CATALYST OF A CATALYTIC METAL SELECTED FROM THE GROUP CONSISTING OF PLATINUM, PALLADIUM, RHODIUM, RUTHENIUM, NICKEL AND COBALT, WHICH COMPRISES WITHDRAWING A PORTION OF SAID LIQUID FROM SAID BODY, RECYCLING THE WITHDRAWN PORTION BY INTRODUCING THE LATTER THROUGH A FIRST NOZZLE INTO SAID BODY OF LIQUID AT A POINT BELOW THE SURFACE OF SAID BODY AND INTO A SMALL CYLINDRICAL TUBE IMMERSED IN SAID BODY AND HAVING AN INLET, INTRODUCING HYDROGEN THROUGH ANOTHER NOZZLE IN SAID BODY OF LIQUID AND INTO SAID INLET OPENING, THE RECYCLED LIQUID HAVING A VELOCITY OF 5-100 METER PER SECOND AT ITS POINT OF INTRODUCTION INTO SAID BODY, THE RATIO OF THE VOLUME OF THE RECYCLED LIQUID TO THE VOLUME OF HYDROGEN INTRODUCED THROUGH THIER RESEPECTIVE NOZZLES BEING FROM 1:5 TO 1:01, THE EXOTHERMIC HYDROGENATION ACTION OCCURING IN SAID CYLINDRICAL TUBE AS THE HYDROGEN AND LIQUID JET FROM THE INLET OPENING OF SAID TUBE AND THROUGH SAID TUBE, INDUCING BY THE JETTING ACTION OF SAID LIQUID IN SAID BODY OF LIQUID IN SAID CYLINDIRCAL TUBE A CIRCULATION OF ADDITIONAL LIQUID DRAWN THROUGH SAID CYLINDRICAL TUBE IN AN AMOUNT OF ABOUT 10 TO 100 TIMES THE AMOUNT OF THE RECYCLED LIQUID SUPPLIED THROUGH SAID FIRST NOZZLE, SAID ADDITIONAL LIQUID ALSO DRAWN DISSIPATING IMMEDIATELY THE HEAT OF THE EXOTHERMIC HYDROGENATION ACTION IN SAID CYLINDRICAL TUBE, AND THE INLET OPENING OF SAID TUBE HAVING A MEAN DIAMETER OF 2 TO 20 TIMES THE MEAN DIAMETER OF SAID FIRST NOZZLE AND THE CYLINDRICAL TUBE HAVING A LENGTH OF 3 TO 30 TIMES ITS HYDRAULIC DIAMETER.
