以ＫＦ／Ａｌ２Ｏ３作催化剂合成月桂氮Ｚｈｕｏ酮（１），在已内酰胺、溴代十二烷、催化剂的摩尔比为１．００：１．２０：０．２０７，反应温度６０－６５℃下，反应３，５ｈ，Ｉ的收率为９４．３％，产品Ｉ在粗品中的含量达９４．７％，已内酰的含量小于０．１％，精制后Ｉ的含量为９８．８％，总收率为８８．３％。

Laurocapram (I) was synthesized in the presence of potassium fluoride on Alumina.The optimum production conditions were as follows:caprolactam:1 bromododecane:catalyst was 1 00∶1 20∶0 207(mol),reaction temperature was 60～65℃,and reaction time was 2h.Under the optimum conditions,the yield of I was 94 3%,the content of I reached 94 7%,and the caprolactam was less than 0 1%.When I was purified,its content cou...
