摘　　要：作为铃兰花香精重要配制原料之一的铃兰醛,有多种合成方法,其中大部分方法工艺路线复杂、生产成本高,故而有必要研究操作简单、环境污染小、产品质量高且成本低的工艺路线。作者在碱性条件下,选择正丙醛和对叔丁基苯甲醛通过羟醛缩合脱水反应,制备合成铃兰醛的原料对叔丁基-α-甲基肉桂醛,该原料通过加氢反应可合成铃兰醛。Lilac aldehyde,one of the most important raw materials for the production of lilac flower flavor,has many synthetic methods,most of which involve complicated processes and high production costs.Therefore,it is necessary to study the technological process with simple operation,low environmental pollution,high product quality and low cost.In this paper,n-propionaldehyde and p-tert-butylbenzaldehyde were selected to synthetic p-tert-butyl-α-methyl cinnamaldehyde by aldol condensation dehydration under alkaline conditions.Aldehyde was synthesized by hydrogenation of this compound.
