Abstract
A process for producing isomerized olefins, branched aldehydes, branched alcohols, branched surfactants and other branched derivatives through isomerization, hydroformylation, hydrogenation, surfactant forming reactions and other derivative forming reactions.
Claims15
A process, comprising the steps of:
- providing a first catalyst comprising an organometallic complex, said organometallic complex comprising at least one of a rhodium and a cobalt and at least one of an organophosphorus ligand;
- providing one or more of a C4-C36 linear alpha olefin;
- providing a gas phase comprising CO;
- isomerizing said linear alpha olefin by said first catalyst in the presence of the CO at a first pressure to produce an isomerized olefin;
- and
- hydroformylating said isomerized olefin by said first catalyst in the presence of CO and H2 at a second pressure higher than said first pressure producing a branched aldehyde.
3 more elements
The process according to 15, wherein said organophosphorous ligand is a phosphite ligand which is tris (2, 4-di-t-butylphenyl) phosphite.
The process according to 15, further comprising:
- a first organophosphorous ligand which is triphenylphosphine;
- and
- a second organophosphorous ligand which is tris (2, 4-di-t-butylphenyl) phosphite.
