ISOMER COMPOSITION CONTAINING OPTICALLY ACTIVE TRANS-1-(2,2,6-TRIMETHYLCYCLOHEXYL)-2-BUTEN-1-ONE OR MIXTURE OF THE SAME AND EXCELLENT IN CHEMICAL RESISTANCE AND PERFUME COMPOSITION CONTAINING THE ISOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a geometrical isomer composition excellent in chemical resistance, applied for a base material containing an alkaline chemical or an acidic chemical, suppressing time-dependent deterioration and discoloration of the base material when exposed to lights and having uniquely fruity and floral perfume with high preference.;SOLUTION: The geometrical isomer consisting of 93-99 wt.% optically active trans-1-(2,2,6-trimethylcyclohexyl)-2-buten-1-one expressed by formula (1) or a mixture with the same and 7-1% optically active cis-1-(2,2,6- trimethylcyclohexyl)-2-buten-1-one expressed by formula (2) or a mixture with the same is used: formula (1); (1R,6S)-form and (1S,6R)-form, formula (2); (1S,6S)- form and (1R,6R)-form.;COPYRIGHT: (C)2004,JPO
