Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: wherein Ris C&#x2013;Cstraight chain alkyl or C8-alkenyl; and wherein Ris C&#x2013;Calkyl, C&#x2013;C2-alkenyl, C3-alkenyl or Cnon-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:R&#x2014;CH&#x2014;CH(OR)(ii) then carrying out a thermal decomposition reaction at pH&#x3c;7 and then (iii) fractionally distilling the resulting reaction product to provide the enol ether.

Acyclic enol ethers, isomers thereof, organoleptic uses thereof and processes for preparing same

Described is a process for qualitatively and quantitatively substantially continuously analyzing the aroma emitted and rates of emission of the aroma components thereof from two or more different varieties and/or species of living flowers at a given point in time or over a given time period using a single enclosure to contain the living flowers and having aroma trapping means attached to the single enclosure and apparatus for carrying out such process. Also described is a process for preparing one or more perfume compositions comprising the steps of carrying out the aforementioned analysis or analyses and then, using the results of such analysis or analyses, providing and admixing at least the major components found in the analysis or analyses; apparatus for carrying out such process and perfume compositions prepared using such apparatus and process.
