PROCESS FOR PREPARING JET FUEL FROM MOLECULES DERIVED FROM BIOMASS

The invention relates to a process for preparing jet fuel or jet fuel precursors which comprises the treatment of a charge derived from biomass, the said charge comprising at least one compound chosen from terpenes of formula [CH2=C(CH3)CH=CH2]n, in which n is an integer of from 2 to 12, the carbon chain of which is linear, cyclic or branched, or cyclic or branched terpenes as defined previously, which have been chemically modified by oxidation and/or rearrangement of the carbon backbone, the said process comprising a cycloaddition step (i) followed by a cracking and hydrogenation step (ii).

Synthesis of p-Camphorene

p-Camphorene is synthesised by the application of Wittig reaction with methylenetriphenylphosphorane on 1(4-methyl-3-pentenyl)-4-(5-methyl-4-hexe-1-one)cyclohex-1-ene (5), the cardinal intermediate, which was procured by the formation of β-ketosulphoxide and then its subsequent alkylation with 1-bromo-3-methyl-2-butene of the compound 1(4-methyl-3-pentenyl)-4-carbmethoxycyclohex-1-ene (3).The alkylated material was submitted to reductive cleavage with aluminium amalgam in aqueous THF at 65 deg to furnish 5.
