Synthesis method of trans-2-hexenol

The invention discloses a synthesis method of trans-2-hexenol, and belongs to the field of organic synthesis. The method specifically comprises the following steps: adding aluminum isopropoxide into isopropanol, heating and stirring, dropwise adding trans-2-hexenal, reacting while refluxing to distill out the product acetone, heating to distill out the residual isopropanol after GC detects that the trans-2-hexenal is less than 1%, and carrying out continuous vacuum distillation on the obtained trans-2-hexenol crude product to obtain the high-purity trans-2-hexenol, the route process is stable, the reaction condition is mild, the product has competitive advantages, and the product can be used for preparing fruit type essences such as strawberries and apples after being diluted. 本发明公开了一种反式2-己烯醇的合成方法，属于有机合成领域。具体操作包括：向异丙醇中加入异丙醇铝，升温搅拌后，滴加反式2-己烯醛，边反应边回流蒸出产物丙酮，待GC测得反式2-己烯醛小于1％后，升温蒸馏出剩余的异丙醇，得反式2-己烯醇粗品经过连续减压精馏得高纯度反式2-己烯醇，本发明路线工艺稳定，反应条件温和，产品具有竞争优势，产品稀释后还可用以配制草莓、苹果等水果型香精。
