补充资料:壬酸
分子式:C9H18O2
分子量:158.24
CAS号:112-05-0

性质:无色或淡黄色油状液体。工业品有淡黄色。微有特殊气味。熔点11-12.5℃,沸点255.6℃,相对密度(20/4℃)0.904-0.910,折射率(nD20)1.4322。溶于乙醇、氯仿和乙醚等有机溶剂,不溶于水。

制备方法:该品天然品(游离或酯化状态)存在于玫瑰、香叶、鸢尾、酒花、薰衣草等精油中。工业上由1-辛烯或油酸氧化而得。1.油酸经硝酸或臭氧氧化。2.以1-辛烯和合成气为原料,经羰基化制得壬醛,然后经空气氧化得到壬酸。实验室制备时可将重蒸过的丙二酸二乙酯加入丁醇钠,加热至80-90℃,加入溴庚烷,使反应物缓缓回流至石蕊呈中性。然后加入氢氧化钾溶液,加热回流4-5h,皂化完成后进行水蒸汽蒸馏,蒸至不再有丁醇馏出。将浓盐酸加入残液中,回流1h后冷却分出油层加热,至180℃当停止放出二氧化碳时,反应物中的油状物即粗品壬酸。减压蒸馏,收集140-142℃(1.6kPa)馏分,得成品壬酸,收率约70%。

用途:有机合成原料,经氧化可制壬二酸,经氨化氢化可制壬胺,加压氢化可制壬醇。壬酸也用于生产壬酸酯类增塑剂,还用作油漆干燥剂。壬酸呈淡的脂肪和椰子香气,我国 GB2760-86规定为允许使用的食用香料,主要用来配制椰子和浆果类香精。
