性质描述: 无色油状液体。凝固点15℃,沸点228℃,相对密度0.8295(17.3/4℃),折光率1.43002(17.3℃),闪点88℃。溶于醚和醇,不溶于水。
生产方法: 由癸酸与冰醋酸经缩合、消除反应而得。将反应管内吸附了乙酸镁的浮石催化剂升温,在450℃活化2h,冷却至400℃,然后在380-400℃,以每小时2000ml的流量,将癸酸与冰醋酸混合液从反应管上部加入,先经过装有瓷环的汽化段,再进入装有催化剂的反应段,最后通过冷却段出料。收集得到的反应液用热水洗涤,分去水层,取油层进行减压蒸馏,收集130-146℃(2.67kPa)馏分,得甲壬酮。收率75%以上。
用途: 用于药物和香料的生产,本身也可作为香料使用。是气相色谱分析的标准物质。
