Catalytic process for the production of diolefins
Abstract
Abstract 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.
