  • Patent number: 7175871
    Abstract: Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: wherein R1 is C4–C10 straight chain alkyl or C9 8-alkenyl; and wherein R2 is C1–C4 alkyl, C3–C4 2-alkenyl, C4 3-alkenyl or C10 non-allenic alkadienyl and uses thereof in imparting, augmenting or enhancing the aroma and/or taste of a consumable material such as a perfume composition, a cologne, a perfumed article such as a soap, cosmetic, hair preparation or detergent, a foodstuff, a chewing gum or an alcoholic or non-alcoholic beverage such as a carbonated beverage or fruit liquer. Also described is a process for synthesis of such enol ethers by means of (i) first forming an acetal having the structure: R1—CH2—CH(OR2)2 (ii) then carrying out a thermal decomposition reaction at pH<7 and then (iii) fractionally distilling the resulting reaction product to provide the enol ether.
