桉树脑分子式：C10H18O分子量：154.24CAS号：470-82-6性质：无色油状液体。熔点1.5℃，沸点176-177℃，相对密度0.921，折光率1.455，闪点50℃。溶于12-15倍容积的50%乙醇，4倍的60%乙醇， 1.5-2倍的70%乙醇。溶于氯仿、乙酸及挥发油，微溶于乙醚。具有樟脑样香气和清凉味道。制备方法：桉树脑广泛存在于天然芳香油中，为桉叶油的主要成分。桉树脑可以芳香油中单离制得。例如将桉叶油分馏，收集175-180℃馏分，稍加精制即可。如需制造纯度较高的产品，可将芳香油中分馏得到的桉树脑加以冷却，通入HCI干燥。分离出盐酸及桉树脑结晶，用热水分解结晶，再经精馏即得纯粹的桉树脑。合成法是将萜品转化成酸，再脱水而得。用途：用于口腔剂香精的调配和医药产品的制造，作为食品添加剂，日本《食品添加物公定书》规定桉树脑纯度85%以上，不得用于加香以外的目的。
