    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: The present invention provides a process for continuously preparing a mixture of cyclohexanone and cyclohexanol comprising, a) hydrogenating phenol with gaseous hydrogen, in the presence of platinum or palladium, in a hydrogenation reactor, to produce a hydrogenation product stream comprising cyclohexanone, cyclohexanol, phenol and hydrogen; b) cooling the hydrogenation product stream to a temperature such that the fraction of phenol by mass in a first gas phase is lower than the fraction of phenol by mass in a first liquid phase; c) separating the first gas phase from the first liquid phase; d) returning at least part of the first gas phase to the hydrogenation reactor; e) heating the first liquid phase; f) purifying the first liquid phase by distillation; characterized in that heat is transferred from the hydrogenation product stream in step b) to another part of the process by means of in-process heat exchange; a mixture of cyclohexanone and cyclohexanol obtained by the process; and a chemical plant suitable for continuously preparing mixture of cyclohexanone and cyclohexanol according to the process.

    摘要: Provided is a process in which cyclization of a compound having, in a molecule, a formyl group and a double bond which allow carbonyl-ene cyclization, the compound existing as a mixture of optical isomers thereof, increases the ratio of a particular optical isomer not only in a cyclized compound, but also in an unreacted compound. The process comprises performing, in the presence of a specified aluminum complex represented by the general formula: [Al2(L1)n(L2)3-n]m, cyclization of a compound having, in a molecule, a formyl group and a double bond which allow carbonyl-ene cyclization, the compound existing as a mixture of optical isomers thereof, to increase the ratio of a particular optical isomer.
