VETIVER OIL OR VETIVEROL, PRODUCTION THEREOF AND PERFUME COMPOSITION CONTAINING SAME

摘要

PURPOSE:To provide a vetiver oil vetiverol giving excellent fragrance, containing a relatively large amount of kussmaul and a relatively small amount of isovalensenol. CONSTITUTION:The alcohol component in a vetiver oil or vetiverol is esterified using pref. benzoic anhydride or the like followed by heating to normally ca.130-200 deg.C to thermally decompose the ester of isovalensenol. Thence, the residual ester is hydrolyzed using e.g., sodium hydroxide to separate the alcohol component, thus obtaining the objective vetiver oil or vetiverol containing =40wt.% of kussmaul and =10wt.% of isovalensenol.
