    摘要: The present invention primarily concerns the use of compounds of the following formula (I) wherein X represents an oxygen atom, a —CHO, an —OH, or a —CH2OH group, a single bond or a double bond is present at the respective location of one of the dotted lines, at least one double bond is present when X is an OH group, and the 3-isopentyl or 3-isopent-2-enyl residue is connected to the ring in the ortho, meta, or para position to the X group, as perfuming and/or flavouring agents. The invention further relates to fragrance and flavour compositions containing one or more of these compounds, perfumed or flavoured articles comprising one or more of these compounds and corresponding processes for imparting, modifying and/or enhancing certain odour notes.

    摘要: Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the treated cleavage reaction mixture contains no greater than 50 wppm of the acid catalyst or no greater than 50 wppm of the basic material.
