ABSTRACT:
Described is a two-step process for producing phenyl- and cyclohexyl-substituted oxybutane derivative-containing mixtures of our invention by means of first reacting methyl ethyl ketone with benzaldehyde in the presence of a sulfonic acid catalyst to produce a mixture of phenyl pentenone derivatives; and then hydrogenating the resulting mixture of phenyl pentenone derivatives in the presence of a hydrogenation catalyst, as well as the product produced thereby; and perfumery uses thereof for augmenting, enhancing or imparting aromas in or to perfume compositions, colognes and perfumed articles.
