Abstract
A process for producing isomerized olefins, branched aldehydes, branched alcohols and branched surfactants through isomerization, hydroformylation, hydrogenation and surfactant forming reactions.
Claims20
A process, comprising the steps of:
- providing CO and H2;
- providing a first catalyst which is an organometallic complex of rhodium and one type of an organophosphorus ligand or an organometallic complex of rhodium and more than one type of an organophosphorus ligand;
- providing an alpha olefin;
- isomerizing said alpha olefin by said first catalyst in the presence of CO and H2 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 different from said first pressure to produce a branched aldehyde;
- and
- hydrogenating said branched aldehyde to produce a branched alcohol.

A branched surfactant produced by a process, comprising the steps of:
- isomerizing a C4-C36 alpha olefin by a first catalyst having a rhodium metal and an organophosphorous ligand in the presence of a gas phase having CO at a first pressure producing an isomerized olefin;
- hydroformylating said isomerized olefin by said first catalyst in the presence of a gas having CO and H2 at second pressure different from said first pressure producing a C5-C37 branched aldehyde;
- hydrogenating said C5-C37 branched aldehyde to produce a C5-C37 branched alcohol;
- and
- producing a branched surfactant from said branched C5-C37 branched alcohol.
