标题:一种酯的制备方法
摘要:本发明涉及酯类合成技术领域,尤其涉及一种酯的制备方法.本发明提供了一种酯的制备方法,包括以下步骤:将羧酸类物质,醇类物质,四甲基硫脲,N‑氯代丁二酰亚胺和有机极性溶剂混合,进行氧化反应,得到所述酯;所述氧化反应的温度为20~30oc.在所述制备过程中,本发明所述n‑氯代丁二酰亚胺(Ncs)作为氧化剂与四甲基硫脲发生氧化反应,反应生成活性中间体,再与羧酸反应反应生成活性酯中间体,同时得到黄色的单质硫沉淀;活性酯最后再与羟基反应反应生成酯,同时反应生成非常稳定的化合物四甲基硫脲.上述制备过程在室温条件下即可进行,可以降低能耗,同时也不需要使用腐蚀性或不稳定性的物质.

摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
