A PROCESS FOR THE RECOVERY OF COBALT (II) IONS INITIALLY PRESENT IN A FIRST LIQUID MEDIUM CONSISTING ESSENTIALLY OF ACETIC ACID DERIVED FROM THE LIQUID PHASE OXIDATION OF AN ALIPHATIC HYDROCARBON AND THE PRODUCTION OF A FRESH SOLUTION OF THE SAME COMPRISING: (A) INCORPORATING INTO SAID FIRST ACETIC MEDIUM CONTAINING COBALT (II) IONS AND ABOUT 3 TO 15 PERCENT WATER BY WEIGHT A SOURCE OF OXALATE IONS IN A QUANTITY AT LEAST SUFFICIENT TO REACT STOICHIOMETRICALLY WITH SAID COBALT (II) IONS TO FORM COBALT OXALATE (B) FORMING A SOLID PRECIPITATE OF COBALT 8II) OXALATE IN SAID FIRST ACETIC MEDIUM WHILE AT A TEMPERATURE OF ABOUT 20 TO 150*C., (C) SEPARATING SAID PRECIPITATE OF COBALT OXALATE FROM SAID FIRST ACETIC ACID MEDIUM (D) CONTACTING SAID SEPARATED PRECIPITATE OF COBALT OXALATE WITH A SECOND MEDIUM CONSISTING ESSENTIALLY OF ACETIC ACID CONTAINING ABOUT 3 TO 15 PERCENT WATER BY WEIGHT PROVIDED AT AN ELEVATED TEMPERATURE OF ABOUT 60 TO 140*C. AND CONTAINING CALCIUM IONS DISSOLVED THEREIN IN A QUANTITY AT LEAST EQUIVALENT STOICHIOMETRICALLY THE COBALT (II) IONS CONTAINED IN SAID COBALT OXALATE TO FORM CALCIUM OXALATE, (E) FORMING A SOLID PRECIPITATE OF CALCIUM OXALATE IN SAID SECOND ACETIC ACID MEDIUM WHILE SAID COBALT (II) IONS ARE SOLUBILIZED, AND (F) SEPARAING SAID SOLID PRECIPITATE OF CALCIUM OXALATE FROM SAID SECOND ACETIC ACID MEDIUM TO PRODUCE A FRESH SOLUTION OF CO(II) IONS DISSOLVED IN ACETIC ACID.

    Abstract: HYDROCARBON CONVERSION PROCESSES INCLUDING HYDROCRACKING, DENITROGENATION AND HYDROGENATION OF IMPROVED ACTIVITY ARE OBTAINED BY THE USE OF CATALYSTS PREPARED BY ACTIVATING FORAMINOUS REFRACTORY OXIDES COMBINED WITH AT LEAST ONE THERMALLY DECOMPOSABLE AND/OR OXIDIZABLE COMPOUND OF A CATALYTICALLY ACTIVE METAL UPON CALCINATION WHILE CONTACTING THE COMPOSITE WITH AN ACCELERATED FLOW OF AN OXIDIZING GAS AT A RATE OF AT LEAST ABOUT 2 S.C.F.M. PER POUND OF SAID COMPOSITE. FURTHER ADVANTAGE IS REALIZED BY HEATING THE COMPOSITE TO THE PRESCRIBED CALCINATION TEMPERATURE AT A CONTROLLED GRADUAL RATE. IT IS ALSO GENERALLY DESIRABLE TO ASSURE THAT THE INLET TEMPERATURE OF THE OXIDIZING GAS PRIOR TO CONTACT WITH THE COMPOSITE IS LESS THAN ABOUT 500*F.

    Abstract: A NEW CATALYST COMPOSITION USEFUL FOR THE VAPOR PHASE OXIDATION OF NAPHTHALENE TO NAPHTHOQUINONE, HAS BEEN FOUND, SAID CATALYST COMPOSITION COMPRISING SILICON OXIDE, VANADIUM PENTOXIDE AND POTASSIUM SULFATE IN COMBINATION WITH 30 TO 300% BY WEIGHT, BASED ON THE WEIGHT OF THE VANADIUM PENTOXIDE, OF A BORON COMPOUND AS B2O3. THE CHARACTERISTIC FEATURE OF THIS COMPOSITIONS IS TO INCLUDE THE BORON COMPOUND TOGETHER WITH THE SILICON OXIDE. THE TECHNICAL ADVANTAGES OBTAINED THEREBY INCLUDE EXCELLENT SELECTIVITY FOR DESIRED REACTION AND GOOD SERVICE LIFE OVER A LONG RUN OPERATION.

    Abstract: ORGANIC COMPOUNDS ARE DEHYDROGENATED TO COMPOUNDS HAVING A HIGHER DEGREE OF UNSATURATION BY CONTACTING THE FEEDSTOCK IN THE VAPOR PHASE AT AN ELEVATED TEMPERATURE IN THE PRESENCE OF AN OXYGEN-CONTAINING GAS WITH A CALCINED CATALYST CONTAINING A FERROUS GROUP METAL, E.G., NICKEL, IN COMBINATION WITH PHOSPHROUS, AT LEAST ONE GROUP IIA METAL AND OXYGEN. REPRESENTATIVE OF SUCH CONVERSIONS IS THE OXIDATIVE DEHYDROGENATION OF BUTANE TO 1,3-BUTADIENE. THE CONVERSION PRODUCTS ARE VALUABLE COMJPOUNDS PARTICULARYL USEFUL AS INTERMEDIATES FOR THE PREPARATION OF POLYMERIC MATERIALS SUCH AS SYNTHETIC RUBBERS AND THE LIKE.

    Abstract: FLUIDIZED BED CATALYST HAVING AN ATOMIC RATIO OF V:CR:B OF 1:0.5-2.0:0.1-1.2, A TOTAL AMOUNT OF THEIR OXIDES CARRIED ON THE CATALYST BEING 20 TO 80% BY WEIGHT, BASED ON THE WEIGHT OF THE CATALYST AND CLOSED BULK DENSITY OF 0.85 TO 1.20 G./ML. IS PREPARED BY SPRAY-DRYING A SILICA SOL SLURRY CONTAINING A VANADIUM COMPOUND, A CHROMIUM COMPOUND AND A BORON COMPOUND ESPECIALLY PREPARED BY USING A DISSOLUTION AGENT FOR THE BORON COMPOUND, FOR EXAMPLE, A CIS-POLYHYDRIC ALCOHOL HAVING HYDROXYL GROUPS AT AN A- OR B-POSITION MUTUALLY OR AN A-HYDROXYCARBOXYLIC ACID, AT AN OUTLET TEMPERATURE OF A SPRAY-DRIER OF 85* TO 160*C. THE CATALYST IS USEFUL FOR THE PRODUCTION OF AROMATIC NITRILES BY FLUIDIZED BED METHOD.
