Reformed vetiver oil and vetiverol, process for preparing the same, and perfumery composition comprising the same. |
摘要 |
<p>A reformed vetiverol comprising 40% by weight or more of khusimol and 10% by weight or less of isovalencenol is disclosed. The vetiverol, containing a small amount of isovalencenol and a large amount of khusimol imparts a milder and more elegant odor than conventional vetiver oils or vetiverols. The reformed vetiverol can be prepared by a process comprising: esterifying alcohol components in a vetiver oil or a vetiverol, heating the esterified vetiver oil or a vetiverol to thermally decompose isovalencenol esters, hydrolyzing the remaining esters into alcohols, and separating the formed alcohols.</p> |
