摘要： A CATALYTIC PROCESS FOR PRODUCTION OF DIOLEFINS HAVING 4 TO 8 CARBON ATOMS BY VAPOR PHASE OXIDATION WHICH COMPRISES CONTACTING MONOOLEFINS HAVING 4 TO 8 CARBON ATOMS AND OXYGEN WITH A SOLID CATALYST COMPOSITION COMPRISING A CATALYST SYSTEM OF THE FORMULA:

TALA PB MOC FED BIE XF YG OH

WHEREIN A, B, C, D, E AND H EACH REPRESENTS THE NUMBER OF THE RESPECTIVE ATOMS, X IS ONE OR MORE OF NI, CO, MG AND MN, F REPRESENTS THE TOTAL NUMBER OF ONE OR MORE ATOMS OF NI, CO, MG AND MN, Y IS ONE OR MORE OF CU, CA, SR, ZN, CD, SN, BE, CR AND PB, AND G REPRESENTS THE TOTAL NUMBER OF ONE OR MORE ATOMS OF CU, CA, SR, 2N, CD, SN, BE, CR AND PB, PROVIDED THAT, IN CASE OF C BEING 12, A IS 2 OR LESS BUT NOT 0, B IS 0 TO 5, D IS 0.1 TO 20, E IS 0.1 TO 5, F IS 2 TO 15, G IS 0 TO 12, AND H IS DECIDED DEPENDING ON THE NUMBER OF THE OTHER ATOMS AND USUALLY FROM 38.3 TO 128. BY SUCH PROCESS, DIOLEFINS ARE PRODUCED IN A HIGH SELECTIVITY AND AN EXCELLENT YIELD.

摘要： IN THE PREPARATION OF ACRYLIC ACID BY THE GAS PHASE CATALYTIC OXIDATION OF ACROLEIN WITH MOLECULAR OXYGEN IN THE PRESENCE OF STEAM, A PROCESS WHEREIN THE OXIDATION IS EFFECTED N THE PRESENCE OF A CATALYST COMPOSITION CORRESPONDING TO THE FORMULA: MOA BB(LI2 SO4)COD WHEREIN A, B AND D REPRESENT RESPECTIVELY THE NUMBER OF ATOMS AND C IS THE MOL NUMBER OF LITHIUM SULFATE, AND WHEREIN A IS 12, B IS 0.1 TO 9/0, C IS 0.1 TO 9.0 AND D IS 36.25 TO 58.5. THE CATALYST COMPOSITION HAS A HIGH CATALYTIC ACTIVITY WITH A LONG CATALYTIC LIFE, AND ACRYLIC ACID IS PRODUCED IN AN EXCELLENT YIELD WITH A HIGH PURITY BY THE USE OF SUCH COMPOSITION.
