Disubstituted cycloalkanones are prepared from one of 2-cyclopentylidenecyclopentan-1-one, 2-cyclohexylidenecyclohexan-1-one, 2-cyclopentylidenecyclohexan-1-one, or 2-cyclohexylidenecyclopentan-1-one. The resulting compounds were analyzed for their odor characteristics. The different compounds exhibited varied odor characteristics, which were not predictable from the structures of the compounds. The compounds are useful in the preparation of fragrance compositions and products formed from same.
双取代环烷酮可由以下化合物之一制备:2-环戊烯基环戊烷-1-酮,2-环己烯基环己烷-1-酮,2-环戊烯基环己烷-1-酮或2-环己烯基环戊烷-1-酮。所得化合物的气味特征进行了分析。不同的化合物表现出不同的气味特征,这些特征不能从化合物的结构中预测。这些化合物在香料组合物的制备和由其形成的产品中有用。
