Abstract
Methods of making branched isoparaffin compositions derived from natural oil based linear internal olefins are disclosed. Uses of branched isoparaffins formed by such methods are also disclosed.
Claims11
A method of forming an isoparaffin composition, the method comprising:
- providing (a) unsaturated alkyl esters and (b) low-molecular-weight olefins;
- reacting the unsaturated alkyl esters and the low-molecular-weight olefins in the presence of a metathesis catalyst to form a metathesis product comprising metathesized esters and metathesized olefins, wherein the metathesized olefins comprise one or more linear internal olefins;
- separating at least a portion of the metathesized olefins from the metathesis product to form a separated olefin composition, wherein the separated olefin composition comprises one or more linear internal olefins;
- isomerizing the one or more linear internal olefins comprised by the separated separated olefin composition to form a isomerized olefin composition, wherein the isomerized olefin composition comprises one or more branched olefins;
- and
- hydrogenating the one or more branched olefins comprised by the isomerized olefin composition to form an isoparaffin composition.
