Patent ID: 8450549

Claim:
A method for producing a fuel constituent from a bioisoprene composition comprising chemically transforming isoprene in the bioisoprene composition to non-isoprene compounds by: (a) subjecting the bioisoprene composition to heat or catalytic conditions suitable for isoprene dimerization to produce an isoprene dimer and then catalytically hydrogenating the isoprene dimer to form a saturated C10 fuel constituent; or (b) (i) partially hydrogenating the bioisoprene composition to produce an isoamylene, (ii) dimerizing the isoamylene with a mono-olefin selected from the group consisting of isoamylene, propylene and isobutene to form a dimate and (iii) completely hydrogenating the dimate to produce a fuel constituent; wherein the bioisoprene composition is produced by biological means.
