Cobalt salt-phosphine-organoaluminum catalysts for preparing 1 4-dienes |
| abstract |
A CATALYST FOR USE IN PREPARING 1,4-DINES FROM ALPHAMONOOLEFINS AND CONJUGATED DIENES. THE CATALYST IS PREPARED BY MIXING, IN ANY ORDER, AN ORGANOLAMINUM COMPOUND, A COBALT SALT AND AN DIPHENYL ALKENYL OR DIALKENYL PHENYL PHOSPHINE IN A LIQUID MEDIUM, EITHER IN THE PRESENCE OF THE MONOMERS OR SEPARATELY. THE REACTION FOR PREPARING THE 1,4-DIENS IS CARRIED OUT IN AN INERT ORGANIC SOLVENT AT TEMPERATURES OF 25 TO 150*C. AND PRESSURES RANGING FROM 1 ATMOSPHERE TO 2000 P.S.I.G. THE INVENTION PROVIDES CATALYSTS WHICH ARE READILY AVAILBLE AND WHICH FORM 1,4-DIENS AT FEASIBLE RATES WITH A MINIMUM OF BY-PRODUCT FORMATION. |
