橙花醇(英文:Nerol)又称β-柠檬醇,是香叶醇的双键异构体,是一种单萜

性质

无色渍状液体,有玫瑰和橙花的香气。[1]旋光性。几乎不溶于水,与乙醇乙醚氯仿混溶。容易失水生成苧烯

天然橙花醇及其类存在于橙叶油、玫瑰油薰衣草油、斯时兰卡香茅油、苦橙花油和香柠檬柠檬、白柠檬、柚子甜橙等中。[2]

制取

1、使香叶醇氢碘酸反应,用碱除去过量氢碘酸,得到混有香叶醇的橙花醇,再进行水蒸气蒸馏或真空蒸馏,得橙花醇成品。

2、以橙花油为原料,先分馏除去萜类和芳樟醇,取伯醇馏分酯化成邻苯二甲酸酯,经提纯、皂化得香叶醇和橙花醇的混合物,加氯化铅除去香叶醇,残液用上法分离得橙花醇。

3、由柠檬醛异丙醇铝-异丙醇溶液中还原,再经分离而得。

4、用芳樟醇在乙酐-乙酸钠存在下加热酯化,经皂化得到香叶醇和橙花醇的混合物,用上法分离。

用途

主要用于配制玫瑰型和橙花型等花香香精,草莓、树莓和柑橘类等水果型香精及日用化妆香精等。
