    摘要： Methyl pentanoic acid esters corresponding to the formula ##STR1## wherein R is an olefinically unsaturated, straight-chain or branched-chain or carbocyclic hydrocarbon group, a phenyl or alkyl substituted phenyl group, a phenyl substituted alkyl group, or a phenyl substituted alkenyl group, wherein R contains from 3 to 9 carbon atoms, are valuable perfumes having strong, generally vegetably odor notes and outstanding persistence. They are produced by esterifying 2-methyl pentanoic acid with an unsaturated or carbocyclic alcohol or phenol containing radicals R corresponding to the general formula.The compounds can be effectively combined with other perfumes and standard perfume ingredients to form new compositions. The methyl pentanoic acid ester content thereof generally amounts to between about 1 and about 50% by weight.

    摘要翻译： 对应于式（I）的甲基戊酸酯其中R是烯属不饱和的，直链或支链或碳环烃基，苯基或烷基取代的苯基，苯基取代的烷基或苯基 取代烯基，其中R含有3至9个碳原子，是有价值的香料，具有强烈的，通常是有趣的气味香料和出色的持久性。 它们通过用含有与通式相应的基团R的不饱和或碳环醇或苯酚酯化2-甲基戊酸来制备。 这些化合物可以与其他香料和标准香料成分有效结合形成新的组合物。 其戊酸酯的甲基酯含量通常为约1至约50重量％。
