Patent ID: 6894020

Claim:
A process for augmenting, enhancing or imparting a musk aroma in or to a consumable material selected from the group consisting of a perfume composition, a perfumed article and a perfumed polymer comprising the step of intimately admixing an aroma augmenting, enhancing or imparting quantity and concentration of a macrocyclic musk composition, said macrocyclic musk composition provided by the steps of: (a) admixing a cyclotetradecenone reactant mixture comprising greater than 45% by weight of Δ 3 -cyclotetradecen-1-one and greater than 15% by weight of Δ 2 -cyclotetradecen-1-one with a hydrogenation reaction solvent to form a solvent-reactant mixture with the weight ratio of solvent:cyclotetradecenone reactant mixture being from 20:70 up to 70:20; (b) treating the resulting solvent-reactant mixture with hydrogen in the presence of a chemo-selective hydrogenation catalyst in a concentration of from about 0.1% up to about 0.5% by weight of the reaction mixture, at a temperature in the range of from about 15° up to about 35° C. and at a pressure of from about 0 psig up to about 100 psig thus forming a hydrogenated product reaction mass, whereby a composition comprising, on a solvent-free basis, greater than 40% by weight of cyclotetradecanone, greater than 40% by weight of Δ 3 -cyclotetradecen-1-one and less than 5% by weight of Δ 2 -cyclotetradecen-1-one is produced (c) recovering the resulting macrocyclic musk composition from the hydrogenated product reaction mass; and admixing the resulting macrocyclic musk composition with a consumable material base.
