Abstract: A PROCESS FOR THE CONTINUOUS PRODUCTION OF DIBROMOBUTENES BY THE REACTION OF BUTADIENE WITH BROMINE IN THE GAS PHASE, IN WHICH BUTADIENE IS USED IN MORE THAN DOUBLE THE STOICHIOMETRIC AMOUNT AND THE REACTANTS RE IN TURBULENT FLOW. DIBROMOBUTENES ARE INTERMEDIATES FOR POLYAMIDES OF THE NYLON-6,6 TYPE.

Abstract: A PROCESS FOR PRODUCING 1,4-DICYANOBUTENE-(2) IN WHICH AT LEAST ONE OF THE COMPOUNDS 1,2-DIBROMOBUTENE(3) OR 1,4-DIBROMOBUTENE-(2) IS REACTED WITH HYDROCYANIC ACID IN THE PRESENCE OF A COPPER SALT CATALYST. THE PROCESS TAKES PLACE IN THE PRESENCE OF AN AQUEOUS ACID MEDIUM AND IN THE PRESENCE OF AN ACID ACCEPTOR. DURING THE REACTION A PH OF FROM -1TO +3 IS MAINTAINED. THE HYDROGEN BROMIDE THAT IS PRESENT IN THE REACTION SOLUTION IS OXIDIZED TO ELEMENTARY BROMINE AND THE AQUEOUS SOLUTION CONTAINING THE ACID ACCEPTOR IS RECYCLED TO THE REACTION MIXTURE. THE RATE OF REACTION OF THE PROCESS IS CONSIDERABLY HIGHER THAN THAT OF CONVENTIONAL METHODS AND LOWER YIELDS OF BY-PRODUCTS ARE ACHIEVED.

Abstract: 1,168,695. Mixing apparatus. BADISCHE ANILIN-& SODA-FABRIK A.G. 15 Feb., 1967 [16 Feb., 1966], No. 7234/67. Heading B1C. [Also in Division C2] An apparatus for mixing gases, e.g. bromine and butadiene, in such a way as to produce turbulent flow (the Reynold number being above 2300), comprises a loop-shaped reactor 4 into which the gases are continuously introduced via nozzles 3 and 7 at such a velocity that the impulse transmitted to the gas causes it to circulate. The gases may be produced by evaporating liquids stored in tanks 1 and 5. Any liquid condensing in the bottom of the reactor may be recirculated via pump 9, condenser 10 and nozzle 8; discharge is effected through tank 11.

Abstract: Supported catalysts containing silver and alkali metals, for the preparation of ethylene oxide from ethylene and oxygen in the gas phase, are prepared or regenerated by modifying, respectively, a new or spent supported catalyst which already contains metallic silver and may or may not contain the light alXall metals lithium and/or sodium and, where a spent Catalyst is concerned, also contains the heavy alkali metals potassium, rubidium and/or cesium with asolution containing the heavy alkali metals, the modifier solution used containing a) a surfactant and/or a reducing agent, in the case of the preparation of a new catalyst or b) a surfactan, in the case of the regeneration of a spent catalyst,
